6 NMS Feature Description & Operation Issue 1 1. Introduction 1.1 Overview ipecs NMS is a Web-based MS-Windows application software that provides system monitoring and management features communicating with multiple ipecs systems using standard Simple Network Management Protocol (SNMP) for communication across the network. The purpose of this software is to assist in operation of the ipecs systems allowing for convenient and efficient management operation and problem status of the Systems being monitored. The Web-based software architecture provides Network Managers the added benefit of remote accessibility to the NMS server using a Web browser interface for the NMS client. 1.2 Feature Summary ipecs-nms is comprised of three services: NMS Server Management, System Management, and System Monitoring. The following graphic illustrates the features of each, and they are described below: 1

7 NMS Server Management NMS Server Management is for the configuration of common operating parameters of the NMS server and for managing NMS operation history & log. It provides NMS user-related features such as NMS user registration, access control, system assignment and notification configuration. NMS operational history can be checked using the NMS Access Log & Operation Log, and ipecs-nms Control program that is a separate MS-Windows application supporting NMS service-related features such as the execution of the ipecs-nms Service and backup & restore operations on the NMS local database. System Management System Management is for facilitating efficient management & operation of ipecs systems. It provides features for registering ipecs systems to the NMS server, creating system groups, and managing system Web Admin passwords for direct access to ipecs System Web Admin through ipecs-nms. Call Statistics operations present tables and graphs with traffic analysis data for attendant calls, completed calls, CO group calls, and voice mail service requests as well as various tables for DECT statistics information. In regard to Station Message Detail Recording (SMDR) data, the System Management facet of the program additionally provides searching operations in table format for detailed analysis. ipecs device firmware can be upgraded using Firmware Upgrade operations for specified systems at a designated time, and system database, system greeting and prompt files can be uploaded or downloaded. 2

8 System Monitoring System Monitoring provides features for monitoring the operational status of ipecs systems. General system configuration information and detailed device information can be examined, and real-time status information of each device and its channels is also provided. Device channel status information is displayed in either device-based or CO/Station channel-based format. An Alarm/Fault management feature provides information on normal and abnormal system status changes and stores them in a log so that they can be managed by the administrator. Network Traffic Monitoring feature provides a means to monitor network traffic and connection status for general network devices as well as ipecs devices. 3

9 2. Installation 2.1 System Requirements NMS Server Requirements When 20 or less systems are to be registered: CPU Intel Core 2 Duo 2.33 GHz or higher RAM 2 GB or higher HDD At least 4 GB of free disk space O/S Microsoft Windows XP Professional or Windows Server 2003 (32-bit Version with NTFS File System) Display 1280 x 1024 or higher When 200 or less systems are to be registered CPU Intel Dual-Core Xeon 2.4 GHz or higher RAM 2 GB or higher HDD At least 20 GB of free disk space O/S Microsoft Windows XP Professional or Windows Server 2003 (32-bit Version with NTFS File System) Display 1280 x 1024 or higher When 500 or less systems are to be registered CPU Intel Quad-Core Xeon 2.66 GHz or higher RAM 2 GB or higher HDD At least 50 GB of free disk space O/S Microsoft Windows XP Professional or Windows Server 2003 (32-bit Version with NTFS File System) Display 1280 x 1024 or higher ipecs System & Device Requirements MFIM Firmware version 5.0 or higher (ipecs-50/100/300/600) Gateways and IP-phones developed before ipecs Phase 3 can be used for basic NMS features. However, in order to support all the additional features provided by NMS (e.g. ipecs device traffic monitoring), those developed after ipecs Phase 4 should be used, and firmware should be upgraded with latest versions that support NMS features. 4

10 2.2 Software Installation Procedure ipecs NMS Software Components Software components needed for ipecs NMS are: PostgreSQL DBMS (PostgreSQL Global Development Group) Apache HTTP Server (The Apache Software Foundation) PHP Hypertext Preprocessor (The PHP Group) Zend Optimizer (Zend Technologies Ltd.) Microsoft Message Queue (Microsoft Corporation) ipecs-nms Server (LG-Nortel) Software components listed above should be installed in the sequence described in this document. Since there are additional configurations during the installation procedure, the installer should read this section carefully before starting software installation Installing Software Components PostgreSQL Installation After decompressing the PostgreSQL software into a temporary folder, double-click on postgresql-8.2.msi file to start the installation procedure (8.2 is the software version in this manual). Perform the following to Install: On the language selection window, select a language and click [Start >]: 5

11 As recommended in the window, close all the programs running on the NMS server and then click [Next >]. The Installation Notes screen will display. The installation notes describe requirements concerning restrictions on the use of the 64-bit version of Windows and FAT32 file system. Read the notes and verify before starting the installation. After reading the Installation Notes, click [Next >] to proceed. On the Installation Options window, select a folder in which PostgreSQL is to be installed (or just note the default location identified by the program), and click [Next >]. 6

12 PostgreSQL is used as a service, check the Install as a service box and enter all field values (as applicable), then click on the [Next >]. In this document, postgres and postgrespw are used for Account Name and Account Password fields, respectively. Of course, other strings can be used for both fields. If the account name configured in the previous step does not currently exist, the Account Error message may appear asking if the account should be created; click [Yes]. If the password configured in the previous step is not complex enough, a Password notification screen may appear to suggest replacing the password with a more complex one. Click [Yes] to change the password to a more complex one (randomly generated string) for increased password security, or [No] to proceed without changing the password. Within the Initialize Database Cluster screen, make the following entries then click on [Next >]: Select the appropriate language / country for Locale field. Select UTF8 for the Encoding (Server) field. (Keep the default value for Client field. v8.3 Option) Enter the Superuser name and the Password to be used internally by the PostgreSQL database. The Superuser Name and Password field values should be noted because they will be used for ipecs-nms Control program when configuring Database User Information. 7

13 Click [Next >] on the Enable Procedural Languages screen. The default value is selected, however, if there is a reason this value may be changed. The Enable contrib. modules screen lists, routines which contribute to the application (default is recommended). Click [Next >] to continue. When the ready to install screen appears, click [Next >] to begin the installation. 8

14 After the installation is complete, the Installation Complete screen will display; click [Finish]. (Because Stack Builder does not need to be executed, Launch Stack Builder at exit check-box may be unchecked before finishing. v8.3 Option) In order for 3rd-party applications like ipecs NMS to use PostgreSQL, a path to the PostgreSQL binary files folder must be set-up. PostgreSQL does not configure the Path during the installation procedure, so this should be done manually. To set-up the Path, perform the following Steps: Access the Control Panel>System Properties, and click on the Advanced tab. Click on the Environment Variables button at the bottom of the screen. 9

15 In the System variables pane, select the Path variable item, and then click [Edit]. On the Edit System Variable screen, check if the bin directory of PostgreSQL already exists in the Variable value field. If it does not exist, append the directory name of the bin folder at the end of the path variable, and then click [OK]. NOTE When entering the path to the PostgreSQL bin folder, type a semicolon (;) at the end of the variable, and then the directory name of bin folder. In this example, the ;D:\Program Files\Postgres\PostgreSQL\8.2\bin string was appended at the end of the Path variable. The modified Path variable is applied after restarting Windows. However, since the new Path is not required until the ipecs NMS Control program is executed, continue the installation without restarting Windows at this time Apache HTTP Server Installation To install the Apache HTTP Server, perform the following: Double-click on the apache_2.2.8-win32-x86-no_ssl.msi file (2.2.8 is the software version used in this manual). 10

16 Click [Next >] button to proceed with the installation. Read the Apache License notes within the License Agreement screen; click [I accept the terms in the license agreement] to accept the terms and then click [Next >] button to proceed. A Read This First screen will display. Once you have read the screen, click [Next >]. In the Server Information screen, fill in the blanks for Network Domain, Server Name, and Administrator s Address fields: -- Administrator s Address field must be entered. -- If HTTP port 80 (the normal HTTP server port) is to be used, select [for All Users, on Port 80, as a Service Recommended]. When finished, click [Next >] to proceed. 11

17 Select the type of installation; if customized installation is not needed, select [Typical] and click [Next >]. On the Destination Folder screen, note the default location for the Apache HTTP Server files, OR Click on the Change button to select a folder where the files should be installed. Click [Next >] to continue. Click [Install] on the Ready to Install the Program window to start installation. 12

18 When done, the Installation Wizard Completed screen will appear; click [Finish] Apache HTTP Server Configuration As the last Installation step, you may wish to modify the Server Side Includes (SSI) related configuration for better security of the Server and AcceptEx related configuration for more stable communication with Apache HTTP Server. SSI exists in HTML files and makes it possible to provide dynamic Web pages. However, because it can be used to execute CGI scripts or shell commands in the Web server, the server may be vulnerable to security attacks. The use of AcceptEx may cause a communication slow-down problem in some cases, and so it is desirable to disable the use of AcceptEx in Apache HTTP Server. In order to remedy these situations, the Apache HTTP Server (httpd.conf) configuration file should be modified: From the Windows Start menu, select Apache HTTP Server 2.2 > Configure Apache Server > Edit the Apache httpd.conf Configuration File; Or, open Program Files\Apache Software Foundation\Apache2.2\conf\httpd.conf using Notepad or another text editor program). Find the Options Indexes FollowSymLinks option string in the opened configuration file (httpd.conf), and comment (disable) it by typing the pound sign (#) before the beginning of the string as shown in the screen capture (shown). Then, type Options IncludesNoExec on the next line; Win32DisableAcceptEx can be inserted after the </Directory> line as in the example below, or appended at the end of the file. 13

19 Apache HTTP Server writes the access log into the access.log file, and the size of the file grows relatively faster depending on the number of access lines to the server. Therefore, as an option, in order to prevent unwanted waste of HDD space by disabling writes to the access log, find CustomLog logs/access.log common string in the configuration file (shown) and disable it by typing pound sign ( # ) before the beginning of the string. When finished, save the configuration file and then close the text editor program. The modified configuration will be applied after restarting Windows or Apache HTTP Server 2.2. However, since the new configuration is not required until the ipecs NMS Control program is executed, continue the installation without restarting Windows at this time.. 14

20 PHP Hypertext Preprocessor Installation To install the PHP Hypertext Preprocessor, perform the following Steps: Double-click on the php win32-installer.msi file to start the PHP Hypertext Preprocessor installation procedure (5.2.5 is the software version used in this manual). On the Welcome to the PHP Setup Wizard screen, click [Next] to proceed. First read the PHP License within the End-User License Agreement screen; click [I accept the terms in the License Agreement] to Accept the terms and then click [Next >] to proceed. 15

21 On the Destination Folder screen, note the default location for the PHP Hypertext Preprocessor, OR Click Change and enter the folder location where the files should be installed. Click [Next >] to continue. On the Web Server Setup screen, select the web server that was installed (Apache version was installed, so the Apache 2.2.x Module is selected on the screen shot shown). Then click on the [Next] button to proceed. Within the Apache Configuration Directory screen, select the configuration (conf) folder in the Apache HTTP Server installation directory, and then click [Next]. In this document, D:\Program Files\Apache Software Foundation\Apache2.2\conf\ directory is selected. 16

22 On the Choose Items to Install screen, click on the expansion box to the left of the [Extensions] node to view the sub-tree. Find the PostgreSQL node on the subtree, and then click down arrow to show pop-up menu. Select Will be installed on local hard drive, and then click [Next]. On the Ready to Install PHP screen, click [Install] to start installation. 17

23 After the installation is completed, click [Finish] to complete installation process. As the last step, in order to prevent possible file transfer failure cause by restrictive maximum file size and execution time limits from default PHP configuration, those settings in the PHP configuration file ( php.ini ) should be modified. From the Windows Start menu, select PHP 5>php.ini to open the PHP configuration file, Or open Program Files\PHP\php.ini using the Notepad or another text editor program.) Find the post_max_size configuration line, and change the configuration value from 8M to 40M. Find the upload_max_filesize configuration line, and change its value from 2M to 40M. 18

24 Find the configuration line of max_execution_time, and change its value from 30 to 90. After finishing the modification, save the configuration file and then close the text editor program Zend Optimizer Installation To install the Zend Optimizer, perform the following Steps: Double-click on ZendOptimizer Windows-i386.exe file (3.3.3 is the software version used in this document). On Welcome to the InstallShield Wizard window, click [Next >] button to proceed. First read Zend Optimizer License Agreement notes. If you agree to the terms and conditions, select I accept the terms of the license agreement and click the [Next >] button. 19

25 On Choose Destination Folder window, select a folder in which Zend Optimizer is to be installed, Or note the default location for installation, then click the [Next] button. Then, on the Choose Web server window, select the web server installed in the previous procedure, and then click the [Next >] button to proceed. Since Apache version was installed, [Apache 2.x] is selected. On Choose the php.ini folder window, the directory of PHP Hypertext Preprocessor software is configured. The php.ini file is saved in the Program Files\PHP directory. After selecting (or noting the default) directory, click the [Next >] button. 20

26 On Choose the Web server root folder window, the Apache HTTP Server installation folder is configured. In this document, the D:\Program Files\Apache Software Foundation\Apache2.2 directory is selected. The Pre-Install Summary window shows the settings that were configured in the previous steps. After checking all the configurations, click on the [Install] button to complete the installation of Zend Optimizer Web Server Restart Following installation, the Web Server Restart window will appear. Before clicking on the [Yes (Y)] button, you must stop the Apache HTTP Server execution by selecting Apache HTTP Server 2.2>Control Apache Server>Stop from the Windows Start menu. Then click on the [Yes (Y)] button. 21

27 After the installation is complete, start the Apache HTTP Server again by selecting Apache HTTP Server 2.2 >Control Apache Server>Start from the Windows Start menu. When the InstallShield Wizard Complete window appears, click [Finish] button Microsoft Message Queue (MSMQ) Installation ipecs NMS utilizes Microsoft Message Queue (MSMQ) one of the software components provided with Microsoft Windows. In many cases, MSMQ is not installed when the Windows OS is installed; verify if it has been installed. In order for the MSMQ to be properly installed, the server should have a Computer Name previously configured. Check this by viewing System Properties in the Control Panel. For Windows XP To verify MSMQ installation, from the Control Panel, select Add or Remove Programs. Click Add/Remove Windows Components. 22

28 In the Windows Components screen, locate the Message Queuing item and verify if it is installed. If it has not been installed (box is not checked), click the checkbox, and then click [Details ]. Message Queuing includes Active Directory Integration. If a domain controller or controller server that provides directory service does not exist, clear the Active Directory Integration checkbox, and click [OK]. After returning to the Windows Components screen, click the [Next >] to start installation. After installation is completed, click [Finish]. 23

29 For Windows 2003 Server From the Control Panel, select Add or Remove Programs. Click on Add/Remove Windows Components. In the Windows Components screen, click on Application Server and click [Details ]. In the Application Server screen, locate the Message Queuing item and verify it is installed. If it is not installed (box is not checked), click on checkbox, and then click [Details ]. 24

30 Message Queuing includes Active Directory integration. If a domain controller or controller server that provides directory service does not exist, clear the Active Directory Integration checkbox, and click [OK]. After returning to the Windows Components screen, click [Next >] to start installation. After the installation is completed, click [Finish] to complete the installation procedure ipecs NMS Software Installation To install the ipecs NMS Software, perform the following Steps: Click ipecs_nms_setup.exe file to start installation; the InstallShield Wizard screen should display. Click [Next >] to proceed. NOTE If required software components have not been properly installed or ipecs-nms Service is installed and running, a warning message may appear. In this case, verify installation of required software or terminate the ipecs-nms Service, and then restart the installation procedure. 25

31 In the Customer Information window, enter the User Name and Company Name fields, and click [Next]. Normally the default destination location for program files need not be modified, click [Next>] to continue. If a different destination is desired, click [Change] and select the new location, and then click [Next >]. On the Select Web service root directory screen, select the htdocs folder under the Apache HTTP Server installation directory, D:\Program Files\Apache Software Foundation\Apache2.2\htdocs was used in this example. After the folder is chosen, click [Next >] to proceed. NOTE if the location for the Apache server files was changed, that directory should be selected by clicking [Change ]. 26

32 Click [Install] to begin software installation. After the installation is completed, click [Finish]. To apply changed configurations, restart your computer Executing ipecs-nms Application The ipecs-nms application is comprised of two programs: ipecs-nms Control (ipecs_nms_control.exe) ipecs-nms Service (ipecs_nms_service.exe) ipecs NMS Service is the main program, which runs as a Windows Service application. ipecs-nms Control registers ipecs-nms Service to the Windows Service list and manages the NMS Service operation and database. 27

33 For registration and execution of ipecs-nms Service, perform the following Steps: In the ipecs-nms installation folder (Program Files\LG-Nortel\iPECS NMS), locate the ipecs_nms_control.exe file and double-click to execute it. (Or, from the Windows Start menu, select LG-Nortel > ipecs NMS > Launch ipecs_nms_control.exe to execute it.) Within the NMS Control screen, enter the User and Password fields using the Superuser Name and Password configured during the installation of the PostgreSQL software. The values postgres and postgrespw were used in this example. Click [Update] when finished making entries. After the two fields are configured, Create Database activates. The NMS local database should be created before registering and executing ipecs-nms Service. Click the [Create Database] button. 28

34 NOTE If a local database already exists, the [Delete Database] is present instead of the [Create Database] button. [Delete Database] should be used with caution; when selected, all information stored in the database is permanently removed. The NMS Client Character Set field normally need not be changed from the default value provided by ipecs-nms Control. However, in some cases the character set used in the NMS server might not be supported by the PostgreSQL database. If this problem should occur, an error message may appear. Select an appropriate Character set from the drop-down list, as needed. If a local database was successfully created, the [Load Service] button will activate; click [Load Service] to register the ipecs-nms Service to the Windows Service list. After the ipecs-nms Service registers, the [Load Service] button will deactivate, and the [Unload Service] and [Start Service] buttons will activate. Click [Start Service] to execute the ipecs-nms Service program as a Windows Service. When running, the [Start Service] button will deactivate and the [Pause] and [Stop Service] buttons will activate. Neither [Stop Service] nor [Pause] should be required for normal operation: [Stop Service] terminates ipecs NMS. [Pause] temporarily suspends execution of the ipecs-nms Service program. Click [Close] to exit the ipecs-nms Control program; the control program does not need to be running while the ipecs-nms Service is in use. 29

35 2.3 ipecs System Admin Configuration Before registering ipecs systems to the ipecs-nms, NMS-related system admin fields should be configured. After logging-in to ipecs Web Admin, click SNMP Attribute (P196) from the System Data list to enter the NMS configuration page. The SNMP Attribute (P196) screen is categorized into three parts: SNMP Agent SNMP Service field is used for enabling or disabling (ON or OFF) the SNMP agent service running on MFIM; this field should be set to ON for communication with ipecs-nms using SNMP protocol. - SNMP Port - Standard SNMP port number 161 should be used unless there is a specific reason for changing this port number. SNMP Security SNMP community and NMS server IP address can be configured; the SNMP community designates a SNMP communication group to which an SNMP message belongs, and is also a logical relationship between the SNMP agent (MFIM) and SNMP manager (NMS). - Read Only Community defines a community string that should be used when SNMP manager (NMS) is trying to read data from the SNMP agent (MFIM), and its default value is set to public - Read Write Community is used for both read and write data by the SNMP manager (NMS), and its default value is private. This value should be the same as set up on the ipecs-nms community string (default=private, but could be changed following 30

36 installation as needed) - Accept SNMP Packet from Any NMS Server if IP Address is not fixed, click to accept SNMP packets from any SNMP manager (or from any IP address), OR - Accept SNMP Packets from These NMS Servers if IP Address is fixed, click to designate IP addresses to be allowed and the method of data transaction (Read Only / Read Write). SNMP Trap configuration is for setting the destination IP address to which Trap messages (ex., alarm/fault events) are to be sent from the SNMP agent (MFIM). Trap Community designates a Trap communication group to which a Trap message belongs, and is also a logical relationship between the SNMP agent (MFIM), and SNMP manager (NMS). This value should be same as the Trap community string defined in ipecs-nms in order for the Trap messages sent from SNMP agent to be accepted by the ipecs-nms server. NOTE Trap communities should be set-up same for all the ipecs systems registered to an ipecs-nms server (default=public, but could be changed following installation as needed), whereas the SNMP community may be defined with different strings for each ipecs system. - Trap Destination is for designating the IP address of the ipecs-nms server, the Trap port number (default=162), and the Trap type field (Notification, Inform, and Trap). Notification defined in SNMPv2c that is sent once without checking the reception of the message. Inform - similar to Notification, but checks the reception of the message using a Response message sent from the receiving SNMP manager (NMS); messages not transmitting a response will be assumed lost and will be sent again (ex., used in an unstable network where there is packet loss, but may decrease network performance when too many messages are present in the MFIM. Trap defined in SNMPv1, but because ipecs-nms and the SNMP agent on MFIM use SNMPv2c, it is not recommended. After finishing all configurations, click on the [Save] button to save and apply the field values. 31

37 3. Getting Started 3.1 Overview of Set-up Once the NMS Server is installed and running, it will monitor registered ipecs systems and be available to service NMS clients, and Web browsers. After initial installation, check the Windows Service status (Section 3.2), and configuration of the following: NMS Management Functions (Section 4.1, NMS Server Management) NMS Users and Authority (Section 4.2, User Accounts Management) Register ipecs Systems for services (Section 4.3, System Management) 3.2 Checking Windows Service Status In order for ipecs-nms to execute properly, verify that Apache HTTP Server, PostgreSQL Database Server, and ipecs-nms are all running as Windows Services. These Windows services may start automatically when the server is restarted, or may be manually controlled using the Windows Administrative Tools for Services: From the Windows Control Panel, double-click on Administrative Tools. Next double-click on Services in the list of available tools. Within the Services window, check or modify the status of services (ex., in this image, the Apache 2.2 service is in Started status, and Startup Type is Automatic ). Using the Properties of a specific Service (right-click on a Service), the Startup Type can be adjusted from Manual to Auto (shown). 32

38 NOTE The status of the ipecs NMS service also can be checked and changed using the ipecs- NMS Control program (refer to ipecs-nms Software Package Installation). 3.3 Accessing the ipecs NMS Server Using a Web Browser ipecs NMS is a Web based application using a Web Browser as the NMS client. Opening your browser and pointing it to the ipecs NMS server automatically opens the NMS client. For optimum performance, use a broadband connection and set the Tools>Internet Options>Temporary Internet Files>Settings or >Browsing History>Settings (depending on your browser version) to Check for newer versions of stored pages, select Automatically. To login to the ipecs-nms, execute the Web browser on the client PC and enter the IP address of the NMS server. 33

39 On the ipecs-nms login page, enter the Admin User ID and Password (ex., Admin and default password ipecsnms were used in this document). Then click on the [Login] button. NOTE The admin account is the ipecs-nms Superuser account and cannot be deleted, but the password can be changed. After logging into the NMS server, the ipecs-nms main page will display. Below, each component of the page is identified followed by a brief description: (3) (4) (1) (5) (2) 34

40 (1) ipecs System Explorer Lists registered systems with Station, CO, and other devices shown in a tree format. If system groups are created to manage systems (refer to Section 4.4.2), those groups are also displayed in tree format. (2) Alarm/Fault Summary For alarm/fault events shows the number of events not yet checked by the administrator. For quick access to events, clicking on [Go to Alarm/Fault Management] moves to the Alarm/Fault management screen. When an alarm/fault event occurs that is configured to play audible alarm in Alarm/Fault Config, an alarm sound is played depending on the setting of Audible Alarm (Toggle=One Time, Repeat, or Disabled). When set to Repeat, alarm can be stopped by clicking [Alarm/Fault Summary] or [Go to Alarm/Fault], or clicking the [Alarm/Fault Analysis] menu tab (Toggle=color change from orange when a new alarm/fault occurs). (3) Information and Control bar - Displays the selected ipecs System Name (on left) and, the NMS User ID and two indicator blocks (on right): - Block #1(left) The left block indicates status of NMS client running on Web browser (blinks at a 5 second interval). - Block #2 The right block indicates communication status between NMS client and server (blinks at a 10 second interval). In the small space to the right of block 2, an animating indicator shows when the NMS client is retrieving data from the MFIM. (4) NMS Menu - Provides tabs to access NMS Web pages for ipecs system related information and the System, User and NMS configuration pages; clicking on a tab moves to the corresponding functional page. (5) Displays functional pages corresponding to each menu Some pages may have a 2 nd -level menu depending on the number of features they provide. To log out from ipecs-nms: Click on the [Log-out] button at the top-right of the screen. If a client web browser is closed without logging-out from the ipecs-nms (by clicking on the [Log-out] button), the client status will be cleared after about 1 minute, automatically logging out the User. The ipecs-nms provides various kinds of information in table format. Most of the tables accept those with row naming (ex., System Information, Additional System Information, Channel 35

41 Information, Device Information, and Device Network Information), support table sort by column order. Click a column header, and the table is arranged in the ascending or descending order of the column. Selection of ascending or descending order toggles each time the column header is clicked. 3.4 NMS Message Exchange Overview ipecs-nms exchanges various types of information with the registered ipecs systems using SNMP/Trap messages. The message types and the information exchanged under each operational situation are as described in the following table: Operational Situation Message Type Message Information ipecs-nms Restart System Restart System Registration ipecs-nms Service is Operating Client is Logged in & Operating (Retrieved by User System Configuration Device Configuration Basic Channel Information Alarm/Fault/System Event (Trap) KeepAlive Message (Trap) Network Traffic Information (if initiated by NMS user) ipecs Firmware File (if initiated by NMS user) Detailed Channel Information Device/Channel Status Information IP Address, Site Name, Firmware Version, Nation Code, etc. IP address, Device Type, Firmware Version, Location Mode, etc. Device Number, Physical Number, Logical Number, etc. Refer to Alarm/Fault/System Event Table.

93 7.2 Call Traffic Configuration To provide Traffic Analysis, ipecs NMS must retrieve and store call traffic statistics from the ipecs system. If enabled, ipecs NMS will request traffic statistics from the ipecs system on a daily basis at 1 am. To enable retrieval and storage of traffic statistics, select [Traffic Config] on the Call Statistics menu, click the check box in the Daily Report field for the desired system, click [Save] to save and apply selections. 7.3 SMDR Analysis SMDR Analysis provides the means to analyze SMDR data downloaded from a registered ipecs system applying various search and sort operations. The page for this feature can be viewed by clicking on the [SMDR Analysis] tab on the Call Statistics menu. 88

94 On the analysis screen, the type of calls (incoming, outgoing, transfer, extension) and various Abandoned Call, external connected party disconnects before answer, records can also be selected for analysis. The records can then be searched by station numbers, CO numbers, call time (duration), date, time, dialed number, ring time (duration), costs and account code. The resulting records are displayed in tabular form with each of the selection and search fields. To start the analysis, first the NMS SMDR log must be loaded with the SMDR data from an ipecs system. The target system for SMDR analysis should be selected first by clicking the system in System Explorer, which displays the system name in the Selected System field. Then, in the SMDR File field, select [Browse ] button to show file open window, and locate the SMDR file. To load the file into the NMS log, click [Load Log Data]. Or, if the SMDR file is not selected or SMDR File field is cleared by clicking [Clear] button, SMDR file is downloaded directly from selected ipecs system into NMS local database after clicking [Load Log Data] button. After reading the SMDR file data into the application, the records may be analyzed with the ipecs NMS tools. To perform an analysis, select the Call Type and complete the desired search fields and click [Search]. NOTE: NMS will ignore any blank search fields during a search. The analysis screen then displays the tabular SMDR report. 89

95 Additional search operations can be performed and are immediately reflected in the table. After modifying Call Type (Direction) and Search Fields, click [Search] to perform a new search. The example above shows a table generated when all normal calls were searched for station 3000 to 3010 and CO 1 to 3 on Feb, 7, In order to download and save the data shown in the SMDR table as an Excel format file, click [Excel Report] button. The picture above shows an example of downloaded Excel file. By clicking [Download SMDR File] button, SMDR file can be downloaded from the selected ipecs system and saved in the NMS user s PC. 7.4 SMDR Statistics SMDR Statistics provides additional presentations of the results from the most recent SMDR Analysis, refer to section 7.3. Results are provided in graphical and tabular formats. After completing an analysis, this page can be entered by clicking [SMDR Statistics] on the Call Statistics menu. 90

96 The Selected System and SMDR File fields cannot be changed here, but just show the system and SMDR file names that were configured and used in SMDR Analysis. These fields can only be changed in SMDR Analysis menu. Additional graphs and tables can be generated by selecting an x and y axis. To apply the selected x and y axis select the type of graph, line or bar. 7.5 DECT Statistics The DECT Statistics screen provides DECT statistics information such as traffic, call, end-of-call, cell, RF access, and station statistics of a DECT gateway as well as the statistics information for all the DECT stations registered to an MFIM. The page for this feature can be entered by clicking [DECT Statistics] tab menu. 91

97 DECT statistics can be classified into two parts. One is the statistics information collected and managed by MFIM, and provides statistics information for all the DECT stations registered to the MFIM. The other one is the statistics information collected and managed by each DECT gateway, and provides various statistics information such as traffic, call, end-of-call, cell, RF access, station statistics of a DECT gateway. As the first step, the target system for DECT statistics should be selected using System Explorer, and then either of [MFIM] or [DECT G/W] is to be selected in order to specify whether the information collected by MFIM or the information from DECT gateway is to be used for data retrieval. The types and meanings of the statistics information provided by MFIM Statistics and DECT G/W Statistics are as follows. Table Name Field Name Description MFIM Statistics DECT G/W Statistics All DECT Station Statistics Traffic Statistics Call Statistics End-of-Call Statistics Cell Statistics RF Access Statistics Station Statistics This provides the statistics data of the number of total and abnormal calls for all the DECT stations registered to an MFIM. The statistics data are collected and managed by MFIM. This provides the statistics data of the wireless hold time and traffic density of a DECT gateway. This provides the statistics data of incoming and outgoing calls for each cell. This provides the statistics data of normal and abnormal end of calls for each cell. This provides the statistics data of the frequency usage for each slot of a selected cell. This provides the statistics data of channel access, handover, and their loads (%) for each cell. This provides the information for normal & abnormal end of calls and the last cell where a DECT station has been most recently located. MFIM Statistics information is retrieved directly from MFIM because its data are collected and managed in MFIM. However, because DECT G/W Statistics data are collected in each DECT gateway, the data should be sent from DECT gateway to MFIM and then retrieved from MFIM to ipecs-nms, which causes some processing delay. All the statistics information received from MFIM is stored into NMS local database, and then presented to NMS users as tables of statistics information. 92

98 After storing the statistics data into NMS local database, NMS user can utilize the information previously stored in the database in order to get the last referenced data (with minimal processing delay). Or, if the current statistics information is needed, all the data can be retrieved again, stored into NMS local database, and then presented to NMS users MFIM Statistics MFIM Statistics information is collected and managed in MFIM, and provides the statistics of total number of calls and abnormal calls for all the DECT stations registered to the MFIM. After checking Selected System field and the [MFIM] radio-button to be selected, check if Statistics Time field shows a date and time. The Statistics Time field value means the date and time when MFIM statistics information was retrieved from MFIM and stored into NMS local database. So, if this field shows a date and time, the statistics data previously stored in NMS local database can be retrieved by clicking [Load Existing Data] button. If this field is blank, it means there is no previously stored MFIM statistics data in NMS local database. In this case, current MFIM Statistics data may be retrieved from MFIM by clicking [Load Current Data] button, and the received data will be stored in NMS local database and then presented to NMS user as a table of statistics information. After clicking on the [Load Current Data] button, current MFIM Statistics information is sent to ipecs-nms, stored in NMS local database, and then presented to the NMS user as a statistics table. While in process, the Loading Status field displays the current status of the procedure, and the types and meanings of the status messages are as follows. Loading Status MFIM Data Requested Description The first step that designates the data request state from ipecs- NMS to MFIM for MFIM statistics data. 93

99 Loading Status Loading Data (NMS MFIM) Description The second step that designates the state of the transmission of MFIM statistics data from MFIM to ipecs-nms. The last step that designates the completion of the transmission of Data Loading Completed MFIM statistics data, and the storage of the data into NMS local database. MFIM statistics data (e.g. number of Call Drops, or other counter values) can be cleared to 0 and statistics data accumulation re-started from the beginning, by clicking on the [Clear Statistics] button. Because this does not remove the statistics data currently stored in NMS local database, the NMS user is still able to retrieve statistics data from NMS local database by clicking [Load Existing Data] button. In order to download and save the currently loaded MFIM statistics data as an Excel format file, click on the [Excel Report] button. The picture above shows an example of the downloaded Excel file. All DECT Station Statistics provides the statistics of total number of calls and abnormal calls for all the DECT stations registered to the MFIM. The meaning of each table field is as follows. Field Name Total Call Description Total number of calls including both normal and abnormal calls. Number of call drops caused by power-off or disconnection of wireless channel. (The Call Drop figure inside the parentheses designates the proportion (%) of call drops to the total number of calls) 94

100 Field Name Description Counted when a DECT station cannot receive an incoming call (no response for No Response signaling messages) due to power-off or other reasons. (The figure inside the parentheses designates the proportion (%) of no responses to the total number of calls) Counted when a call cannot be made because all the codec channels of a DECT Codec Unavailable gateway are already used for other calls. (The figure inside the parentheses designates the proportion (%) of codec unavailable cases to the total number of calls) DECT G/W Statistics DECT G/W Statistics information is collected and managed in each DECT gateway, and provides various statistics information such as traffic, call, end-of-call, cell, RF access, station statistics of a DECT gateway. After checking Selected System field and the [DECT G/W] radio-button to be selected, click on the target DECT gateway in the list of DECT gateways registered to the MFIM. The Statistics Time field value means the date and time when DECT G/W Statistics information was retrieved and stored into NMS local database. So, if this field shows a date and time, the statistics data previously stored in NMS local database can be retrieved by clicking [Load Existing Data] button. If this field is blank, it means there is no previously stored DECT G/W Statistics data in NMS local database. In this case, current DECT G/W Statistics data can be retrieved from MFIM by clicking [Load Current Data] button, and the received data will be stored in NMS local database and then presented to NMS user as tables of statistics information. 95

101 After clicking [Load Current Data] button, current DECT G/W Statistics information is sent to ipecs-nms, stored in NMS local database, and then presented to NMS user as statistics tables. This needs additional procedure and takes relatively longer time than retrieving existing data directly from NMS local database using [Load Existing Data] button. So, in order to give more information about the steps of information retrieval process, Loading Status field displays the current status of the procedure, and the types and meanings of the status messages as listed. Loading Status DECT Data Requested Loading Data (MFIM DECT) Description The first step that designates the data request state from ipecs- NMS to MFIM for DECT G/W statistics data. The second step that designates the state of the transmission of DECT G/W statistics data from DECT gateway to MFIM. The third step that designates the completion of the transmission of Data Loaded to MFIM DECT G/W statistics from DECT gateway, and the storage of the data into a memory space in MFIM. Loading Data (NMS MFIM) The forth step that designates the state of the transmission of DECT G/W statistics data from MFIM to ipecs-nms. The last step that designates the completion of the transmission of Data Loading Completed DECT G/W statistics data from MFIM, and the storage of the data into NMS local database. During the statistics data request and transmission, it is possible to receive an error caused by problems in network communication or in the DECT gateway itself. The types and meanings of the error messages are as follows. Loading Error Description The data transmission from DECT gateway to MFIM has not been No Data in MFIM properly performed due to the internal problem of the DECT gateway. Invalid Data from DECT Data Not Available Malformed or invalid data message has been sent from DECT gateway. DECT gateway had not been properly registered to MFIM when the statistics data were requested to the DECT gateway. 96

102 If it is needed to clear DECT G/W statistics data (e.g. number of Incoming Calls, or other counter values) into 0 and start statistics data accumulation from the beginning, user may click [Clear Statistics] button to initialize the accumulated statistics data in DECT gateway. Because this does not remove the statistics data currently stored in NMS local database, NMS user is still able to retrieve statistics data from NMS local database by clicking [Load Existing Data] button. In order to download and save the currently loaded DECT G/W statistics data as an Excel format file, click on the [Excel Report] button. The picture above shows an example of the downloaded Excel report file. The Excel sheets for DECT G/W traffic, call, end-of-call, cell, RF access and station statistics are shown by clicking corresponding tabs at the bottom of the Excel worksheet. DECT G/W Statistics provides various statistics information such as traffic, call, end-of-call, cell, RF access, station statistics of a DECT gateway. This information can be retrieved by clicking [Load Existing Data] or [Load Current Data] button, and each type of statistics information can be presented by clicking one of the DECT G/W Statistics Type radio-buttons corresponding to the type of statistics information DECT G/W Traffic Statistics DECT G/W Traffic Statistics table is displayed by clicking Traffic radio-button in DECT G/W Statistics Type, and provides the statistics data of the wireless hold time and traffic density of a DECT gateway. 97

103 This table shows statistics data for Total No. of Calls with Hold Time, Total Hold Time, Maximum Call Time, Minimum Call Time, Average Hold Time, and Traffic Density (ELANG). The meanings of the table fields are as follows. (The time fields in the table can have values between 0~ in the unit of seconds, and if the value exceeds the maximum value, FFFFFFFFF will be displayed to indicate overflow.) Field Name Total Number of Calls with Hold Time Total Hold Time Maximum Call Time Minimum Call Time Average Hold Time Description Total number of calls for which wireless connections were completely made.

108 8. Network Traffic Monitoring Network Traffic Monitoring provides the means to monitor the network traffic and the connection status of a network device. For general network devices, Ping test, Traceroute test, and network traffic monitoring features are implemented, and for ipecs devices, Ping test and traffic monitoring features are provided. The pages for these features can be entered by clicking [Network Traffic] tab on the top level menu. 8.1 Ping Test Ping Test provides functions to check the connection status and the packet delay time between ipecs-nms and a general network device, and can be entered by clicking [Ping] tab menu. Before performing Ping test, the IP address of the target network device, and the interval & count for Ping packet transmission should be configured in Ping Configuration & Operation. For Interval field, one of 5, 10, 20, 30 second options can be selected using the combo-box, and Count field can have a value between 1~ Estimated Time field displays an estimated completion time calculated from the values of Interval and Count fields, and is a read-only field that does not require input from user. After the configuration is completed, Ping test can be started by clicking [Start] button. If it is 103

109 needed to stop the Ping test before the completion of the test (before the estimated time), user may click [Stop] button to force the test to be stopped. After the Ping test is started, real-time graph and table that show the result from each Ping test are displayed below. The graph and table that show the result of Ping test can be displayed in three types of time period such as Live Data, Last 60 Minutes, and Last 24 Hours. The real-time graph and table are displayed by clicking [Live Data] button. [Last 60 Minutes] and [Last 24 Hours] buttons are used for displaying the graphs and tables for last 60 minutes and 24 hours from the moment the corresponding button was clicked. (After the test has been finished, they are displayed from the moment of the completion of the test.) The graph in the picture above shows the changes in RTT (Round-Trip Time), which is the time between the transmission of a Ping packet and the reception of the response packet. RTT is often used to estimate the packet delay time in a network environment. The table below the graph shows the information from the Ping test, and the meanings of the table fields are as follows. 104

110 Table Name Field Name Description The IP address of the device that responded to the Ping packet sent Reply IP Address by ipecs-nms. Normally, this is to be the same IP address as the target IP Address configured in Ping Configuration & Operation. Abbreviation of Round-Trip Time. This is the elapsed time until the RTT reception of the response packet to a Ping packet sent by ipecs- Live Data Last 60 Minutes Last 24 Hours Average RTT Delay Variation Time Reply IP Address RTT Average RTT Delay Variation Time Reply IP Address RTT Average RTT NMS. The overall average of the RTT values from all the Ping tests calculated since the beginning of the Ping test. The difference in value between the RTT values of the previous row and the current row of the table. The time when the Ping packet was actually transmitted to the target device. The Time interval may not be exactly same as the Interval value configured in Ping Configuration & Operation depending on the operational or processing load on the NMS server. The IP address of the device that responded to the Ping packet sent by ipecs-nms. Normally, this is to be the same IP address as the target IP Address configured in Ping Configuration & Operation. This is the average of the RTT values from the Ping tests for last 1 minute (actually, the time between the previous row and the current row in the table). The overall average of the RTT values from all the Ping tests calculated since the beginning of the Ping test. The difference in value between the RTT values of the previous row and the current row of the table. The time when the Ping packet was actually transmitted to the target device. The Time interval may not be exactly same as the Interval value configured in Ping Configuration & Operation depending on the operational or processing load on the NMS server. The IP address of the device that responded to the Ping packet sent by ipecs-nms. Normally, this is to be the same IP address as the target IP Address configured in Ping Configuration & Operation. This is the average of the RTT values from the Ping tests for last 1 hour (actually, the time between the previous row and the current row in the table). The overall average of the RTT values from all the Ping tests calculated since the beginning of the Ping test. 105

111 Table Name Field Name Description Delay Variation The difference in value between the RTT values of the previous row and the current row of the table. The time when the Ping packet was actually transmitted to the target Time device. The Time interval may not be exactly same as the Interval value configured in Ping Configuration & Operation depending on the operational or processing load on the NMS server. After the Ping operation is finished, the operation result data can be downloaded and saved as an Excel format file by clicking on the [Excel Report] button. The picture above shows an example of a downloaded Excel report file. The Excel sheets for Live Data, Last 60 Minutes and Last 24 Hours are shown by clicking corresponding tabs at the bottom of Excel program. 8.2 Traceroute Test Traceroute Test provides functions to check the packet delivery path and packet delay time for each hop to the destination between ipecs-nms and a general network device, utilizing ICMP message and the TTL field in IP packet header. The page for this feature can be entered by clicking [Traceroute] tab menu. 106

112 Before performing Traceroute test, the IP address of the target network device and the interval for Traceroute packet transmission should be configured in Traceroute Configuration & Operation. For Interval field, one of 3, 4, 5 second options can be selected using the combobox. After the configuration is completed, Traceroute test can be started by clicking [Start] button. If it is needed to stop the Traceroute test before the completion of the test (before the destination device has been reached), user may click on the [Stop] button to force the test to be stopped. After a Traceroute test is started, real-time graph and table that show the Traceroute result for each hop to the destination are displayed below. The graph of Traceroute test shows the changes in RTT (Round-Trip Time) for each hop to the destination, in real-time. RTT is the time between the transmission of a Traceroute packet and the reception of the response packet, and is often used to designate the packet delay time in a network environment. The table below the graph shows the hops on the path to the destination in sequence, and the RTT from the three trials to the same hop and their average value are displayed together with the Reply IP Address information. The meanings of the table fields are as follows. Field Name Description The IP address of the device that responded with ICMP Time Exceeded message to the Reply IP Address Traceroute packet sent by ipecs-nms. Normally, this is the IP address of a router on the path to the destination or of the target device itself. 107

113 This is the elapsed time until the reception of the response packet to the first Traceroute RTT-1 packet to a device on the path to the destination or the target device. (RTT is the abbreviation of Round-Trip Time.) RTT-2 RTT-3 Average RTT This is the elapsed time until the reception of the response packet to the second Traceroute packet to a device on the path to the destination or the target device. This is the elapsed time until the reception of the response packet to the third Traceroute packet to a device on the path to the destination or the target device. The average of the RTT values from the three Traceroute trials to the same destination. After the Traceroute operation is finished, the operation result data can be downloaded and saved as an Excel format file by clicking on the [Excel Report] button. The picture above shows an example of downloaded Excel report file. 8.3 Device Network Traffic Device Network Traffic provides functions to retrieve network device information and its interface configuration/status, and to monitor the real-time network traffic of the device using SNMP messages. The page for this feature can be entered by clicking [Device Traffic] tab menu. 108

114 Device Network Traffic has two functional parts. One is to retrieve and display general device information and network interface information with Device SNMP Configuration & Operation, and the other one is to present graph and table of real-time network traffic information with Polling Configuration & Operation. These two parts are functionally separated, but because Polling Configuration & Operation part can be working based on the information retrieved in Device SNMP Configuration & Operation, Device SNMP Configuration & Operation part should always be configured and executed first. In order to retrieve device information, the IP Address, SNMP Port, and SNMP Community information should be entered. For SNMP Port field, the standard SNMP port number 161 can usually be used, but if the target device uses different port number for SNMP communication, that port number should be entered. For Community field, public can usually be used for general network devices, but if the target device uses different SNMP community string, that string should be entered. After the configuration is finished, general device information and its interface information can be retrieved and displayed by clicking [Get Device Information] button. Device Information displays general information of the target network device, and the table below shows the device s network interface information. The meanings of the fields are as follows. 109

115 Table Name Field Name Description A textual description of the entity. This value normally includes the full Description name and version identification of the system's hardware type, software operating-system, and networking software. An administratively-assigned name for this managed node. By Name convention, this is the node's fully-qualified domain name. If the Device Information Interface Information Up Time No. of Interface Packet Forward Default TTL Interface Info. name is unknown, the value is the zero-length string. The time (in hundredths of a second) since the network management portion of the system was last re-initialized. The number of network interfaces (regardless of their current state) present on the device. The indication of whether this entity is acting as an IP router in respect to the forwarding of datagrams received by, but not addressed to, this entity. The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this entity, whenever a TTL value is not supplied by the transport layer protocol. A textual string containing information about the interface. This string normally includes the name of the manufacturer, the product name and the version of the interface hardware/software. The desired state of the interface. The Testing state indicates that no operational packets can be passed. When a managed device initializes, all interfaces start with Admin Status in the Down Admin Status state. As a result of either explicit management action or per configuration information retained by the managed device, Admin Status is then changed to either the Up or Testing states (or remains in the Down state). The current operational state of the interface. The Testing state indicates that no operational packets can be passed. If Admin Status is Down then Oper Status should be Down. If Admin Status is Oper Status changed to Up then Oper Status should change to Up if the interface is ready to transmit and receive network traffic. It should remain in the Down state if and only if there is a fault that prevents it from going to the Up state. It should remain in the Not Present state if the interface has missing (typically, hardware) components. 110

116 Table Name Field Name Description The interface's address at its protocol sub-layer. For example, for an MAC Address 802.x interface, this object normally contains a MAC address. For interfaces which do not have such an address (e.g., a serial line), this object should contain an octet string of zero length. The size of the largest packet which can be sent/received on the MTU interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that can be sent on the interface. An estimate of the interface's current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those Speed where no accurate estimation can be made, this object should contain the nominal bandwidth. For a sub-layer which has no concept of bandwidth, this object should be zero. In order to monitor real-time network traffic of the target device, the interval and count for polling network traffic data should be configured in Polling Configuration & Operation. For Interval field, one of 10, 20, 30 second options can be selected using the combo-box, and Count field can have a value between 1~ Estimated Time field displays an estimated completion time calculated from the values of Interval and Count fields, and is a read-only field that does not require input from user. After the configuration is completed, network traffic monitoring can be started by clicking [Start] button. If it is needed to stop the traffic monitoring before the traffic polling is finished (before the estimated time), user may click [Stop] button to force the traffic polling to be stopped. After traffic monitoring is started, real-time graph and table that show the result from each traffic polling are displayed below. 111

117 The graph in the picture above shows in real time the number of incoming and outgoing packets that occurred during the polling interval, and the traffic table shows the traffic data occurred within the interval as well as the accumulated traffic data. The meanings of the table fields are as follows. Field Name In-Interval Out-Interval Total In Description The number of packets received during the time period configured in Interval field of Polling Configuration & Operation. The number of packets transmitted during the time period configured in Interval field of Polling Configuration & Operation. The total number of input datagrams received from interfaces, including those received in error. The number of input IP datagrams for which no problems were encountered to prevent In-Discard their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly. In-Error The number of input datagrams discarded due to errors in their IP headers, the use of unknown or unsupported protocol, or invalid IP address to be received at this device. The total number of IP datagrams which local IP user protocols (including ICMP) Total Out supplied to IP in requests for transmission, and the datagrams for which this device was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. 112

118 Field Name Description The number of output IP datagrams for which no problem was encountered to prevent Out-Discard their transmission to their destination, but which were discarded (e.g., for lack of buffer space). The number of IP datagrams discarded because no route could be found to transmit Out-Error them to their destination. Note that this includes any datagrams which the device cannot route because all of its default routers are down. The time when ipecs-nms retrieved traffic information from the target device. The Time Time interval may not be exactly same as the Interval value configured in Polling Configuration & Operation depending on the operational or processing load on the NMS server. The graph and table that show the result of network traffic polling can be displayed in three types of time period such as Live Data, Last 60 Minutes, and Last 24 Hours. The real-time graph and table are displayed by clicking [Live Data] button. [Last 60 Minutes] and [Last 24 Hours] buttons are used for displaying the graphs and tables for last 60 minutes and 24 hours from the moment the corresponding button was clicked. (After the polling has been finished, they are displayed from the moment of the completion of the polling operation.) And, the interface information that was initially retrieved from the target device by clicking [Get Device Information] button can be retrieved from NMS local database by clicking [Device Information] button. After the Device Traffic operation is finished, the operation result data can be downloaded and saved as an Excel format file by clicking on the [Excel Report] button. 113

119 The picture above shows an example of downloaded Excel report file. The Excel sheets for Live Data, Last 60 Minutes and Last 24 Hours are shown by clicking corresponding tabs at the bottom of Excel workbook. 8.4 ipecs Device Ping Test ipecs Device Ping Test provides functions to check the connection status and the packet delay time between MFIM and an ipecs device that is registered to the MFIM, and this operation is performed by the Ping message implemented in ipecs protocol. The page for this feature can be entered by clicking [ipecs Ping] tab menu. Before executing ipecs Device Ping Test, the target ipecs device to be tested should be selected. After the ipecs system to which the target device is registered is selected in System Explorer, the name of the system is displayed in System field of Selected ipecs Device part, and the list of registered ipecs devices are listed below as a table of devices. 114

120 The target device can be selected in the device table by clicking on the device item, and after the selection is made, the Device Type and IP Address information is displayed in the corresponding fields of Selected ipecs Device part. (If the target device is located behind an NAPT router, NAPT IP Address value will also be displayed.) Before performing Ping test for the selected device, the interval and count for Ping packet transmission should be configured in Ping Configuration & Operation. For Interval field, one of 5, 10, 20, 30 second options can be selected using the combo-box, and Count field can have a value between 1~ Estimated Time field displays an estimated completion time calculated from the values of Interval and Count fields, and is a read-only field that does not require input from user. ipecs Device Ping Test is different from the Ping test for general network device (11.1 Ping Test) in that the Ping packet is sent from MFIM to the target device (rather than sent from ipecs-nms), and so ipecs Device Ping Test can be used to check the network connection and packet delay time between MFIM and the target ipecs device. After the configuration is completed, Ping test can be started by clicking [Start] button. If it is needed to stop the Ping test before the completion of the test (before the estimated time), user may click [Stop] button to force the test to be stopped.

135 10. NMS Database Backup & Restore The ipecs NMS Control program mentioned in section registers ipecs-nms Service to the Windows Service list and manages the NMS Service database and program operation. The earlier section discusses registration and service management. This section discusses the database management aspects of the ipecs NMS Control program. Using the control program, the NMS database can be backed up to a user defined folder and, if the server or other fault occurs, the ipecs NMS database can be restored. The control program permits a Basic Backup & Restore operation that backs up System Management, User Management, NMS Management, and the log data of Alarm/Fault Management and Log Management configuration and log databases. Entire Backup & Restore operation includes detailed information received and stored while ipecs NMS communicates with the ipecs system. The following sections detail operation of both the Basic and Entire Backup and Restore operations Basic Backup & Restore The first step in the basic backup and restore operation is to find and open the ipecs NMS Control program. The ipecs_mns-control.exe program should be located under the ipecs NMS folder in the LG-Nortel folder located in the Program Files directory. When located, double click on the program to open the control window. (Or, from the Windows Start menu, select LG-Nortel > ipecs NMS > Launch ipecs_nms_control. exe to execute it.) Backup & restore for both Basic and Entire Databases should be performed after the ipecs NMS Service stops running, by clicking [Stop Service]. However, in case it is not possible to stop ipecs NMS Service (operational reason), Basic Backup can be performed while ipecs NMS Service is operating, but the changed information during the backup process may not be applied to the database backup file. 130

136 Basic Backup Operation After starting the ipecs NMS Control program and stopping the ipecs NMS Service, a backup may be created. To create the backup, browse to the desired backup location and enter the file name to use for the backup file, and click [Backup]. A DOS command prompt may appear during the creation of the backup file. After complete, check the target folder and assure a backup copy was made. Then, restart the ipecs NMS Service by clicking [Start Service] on the control program, and end the ipecs NMS Control program by selecting [Close] Basic Restore Operation As with the Basic backup operation, the ipecs NMS Control program must be started (refer to Section 9.1). In addition, it is necessary to create an empty database by first unloading the service and deleting the existing NMS basic database. Then the empty database is created and the service is loaded, which allows the database backup file to be restored. This is required in case the existing database is corrupted and assures the corruption will not affect the restored database. 131

137 First open the ipecs NMS Control program window, locate the control.exe file in the LG-Nortel folder in the Program Files directory and double click on the file. This will open the control window. Once the window opens, click [Unload Service] to stop and unregister the service with Windows Service list. After the service is unregistered, the [Delete Database] control activates, click the [Delete Database] control, which removes the existing database. Once the database is deleted, create a new empty database by clicking the [Create Database] control. Now the database backup file can be restored safely to ipecs NMS. Browse to the location and select the backup file, then click [Open]. Click the now active [Start Service & Restore] control, which will load the backup database and restart the ipecs NMS Service program. 132

138 Before restoration begins, you will be asked to enter the PostgreSQL password entered when the program was first loaded, refer to section Enter the password to complete the restoration process. The database is restored to match the Backup database and ipecs NMS Service is loaded and restarted. Click [Close] to close the ipecs NMS Control program Entire Backup & Restore The first step in entire database backup and restore operation is to open the ipecs NMS Control program and stop and unregister the service program with the Windows Service list. The ipecs_mns_control.exe program should be located under the ipecs NMS folder in the LG-Nortel folder located in the Program Files directory. When located, double click on the program to open the control window. (Or, from the Windows Start menu, select LG-Nortel > ipecs NMS > Launch ipecs_nms_control.exe to execute it.) In the control window, select [Unload Service], which will stop and unregister the ipecs NMS Service program. 133

139 Entire Database Backup Operation After stopping and unloading the ipecs NMS Service with the ipecs NMS Control program, a backup may be created. Next, click [Browse ] next to the Entire Database text box and browse to the folder where the backup file will be stored. Next append the file name to the folder path. Note the extension all automatically appends to the folder and file name. Next, click [Backup], a DOS command window appears and, when the backup operation is complete this window will close. After the DOS window closes, check the folder to assure the backup file was created. Activate NMS Service by clicking [Load Service] and [Start Service] then, close the ipecs NMS Control program by clicking [Close] to restore normal operation of ipecs NMS Entire Database Restore Operation Before restoring the entire Database, the ipecs NMS Control program must be started, see section 9.1. In addition, it is necessary to create an empty database by first unloading the service and deleting the existing NMS basic database. Then an empty database is created, which allows the database backup file to be restored. This is required in case the existing database is corrupted and assures the corruption will not affect the restored database. 134

140 To open the control program, locate ipecs NMS Control program in the LG-Nortel folder of the Program files directory and double click the file. (Or, from the Windows Start menu, select LG-Nortel > ipecs NMS > Launch ipecs_nms_control.exe to execute it.) Once the window opens, click [Unload Service] to stop and unregister the service with Windows Service list. After the service is unloaded, the [Delete Database] control activates, click the [Delete Database] control, which removes the existing database. Once the database is deleted, create a new empty database by clicking the [Create Database] control. 135

141 Now the Entire Database backup file can be restored safely to ipecs NMS. Browse to or enter the location and name of the backup file. Click the now active [Restore] control, which will load the backup database. Before restoration begins, you will be asked to enter the PostgreSQL password that was entered when the program was first loaded, refer to section Enter the password to complete the restoration process. The database is restored to match the Backup database. Click [Load Service] and [Start Service] to activate ipecs NMS Service. Click [Close] to close the ipecs NMS Control program. 136

142 NMS Feature Description & Operation Issue 1 Appendix 1 ipecs System Set-up for NMS Before registering ipecs systems in ipecs-nms, the ipecs system should be configured for NMS operation. Login to ipecs Web Admin, refer to the ipecs Administration & Maintenance Manual. Select SNMP Attribute (PGM 196) from System Data group to enter the NMS Configuration screen. SNMP Attributes, as shown on the screen, are divided into three categories: SNMP Agent, SNMP Security, and SNMP Trap. The SNMP Agent field, SNMP Service enables the SNMP agent running in the ipecs Call Server. The SNMP port field defines the udp port used for communications from the ipecs system for SNMP messages. This port should not be changed. In SNMP Security are the Read Only and Read Write SNMP Community fields, 4 to 16 characters. The SNMP community designates an SNMP communication group to which an SNMP message belongs, and is also a logical relationship between the SNMP agent (ipecs A-1-1

143 system) and SNMP manager (ipecs NMS). The SNMP community settings must be the same for the ipecs system and the ipecs NMS server. Read Only Community (default=public) Defines a community string used when the ipecs NMS reads data from the ipecs system. Read Write Community (default=private) Defines the community string used when ipecs NMS reads or writes data to the ipecs system. Although the ipecs system can accept packets from any SNMP manger (ipecs NMS), for improved security, the IP address of specific servers can be defined and allowed Read Only or Read Write access. It is recommended that the system be assigned with the IP address of a specific NMS server with Read Write access. The SNMP Trap configuration defines the Trap Community, and the Trap Destination, which includes the IP Address of the SNMP manager, ipecs NMS, and the message type. The Trap Community designates a communication group to which a Trap message belongs, and is also a logical relationship between the SNMP agent (ipecs system) and SNMP manager (ipecs NMS). This 4 to 16 character string should be the same as the Trap community string defined in the ipecs-nms. The Trap community should be same for all the ipecs systems registered to an ipecs-nms server whereas the SNMP community may be defined with different strings for each ipecs system. The Trap Destination defines the IP address of the ipecs NMS server and the port, 162. Enter the IP address of the NMS server but, the port should not be changed. The pull down menu next to the address is used to define the address type. Three values are available: Trap message type is defined in SNMPv1, but because ipecs-nms and the ipecs system use, and the Trap type message is not recommended Notification message type are, sent from the SNMP agent once without checking the reception of the message. Inform message type requires a response of receipt from the SNMP manager. If the agent does not receive a response, the message is resent. Inform messages A1-2

144 are intended for use in environments with high packet loss; however, use of the Inform message type may detrimentally affect the ipecs system performance. After finishing all Configuration items, click on the [Save] button. A1-3
