9 Chapter 2: Devices and services This chapter discusses the following topics: Topic Page Overview 5 Summary of device technology 5 Supported MIBs 5 Review of the Modular CB QoS CLI 6 Review of the CISCO-CLASS-BASED-QOS-MIB 9 Overview This chapter provides a summary of the Cisco Class-Based QoS device technology, and the associated Management Information Bases (MIBs), that the Cisco CBQoS Technology Pack is designed to support. Summary of device technology Cisco provides a capability called Modular Quality of Service (QoS) in its IOS, which lets you configure the QoS functionality of a router. The Modular QoS Command Line Interface (CLI) enables a user to configure various classes of traffic types and actions for the classified traffic. This is an SNMP pack that will gather metrics based on the CISCO-CLASS-BASED-QOS-MIB file. This MIB is the source of all the metrics reported in this technology pack. The Class Based QoS (CB-QoS) MIB reports metrics that correspond to the classes and actions configured with the CLI. The Cisco CBQoS Technology Pack collects and reports performance metrics gathered from this MIB. This will provide the user with the ability to collect statistics for the class defined under the policy. Supported MIBs The Cisco CBQoS Technology Pack collects performance and accounting data using an SNMP collection model. This technology pack requires read-only access to the SNMP Agents associated with the Cisco Class-Based QoS devices that provide SNMP Agent support. The Cisco CBQoS Technology Pack uses the following MIBs to collect performance and accounting related statistics: CISCO-CLASS-BASED-QOS-MIB CISCO-FRAME-RELAY-MIB IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 5

This section provides an overview of this CLI. Note: This overview does not explain how to configure Modular QoS on a router. For in-depth information about Cisco s Modular QoS, see the Cisco documentation. As documented in the Cisco document, Modular Quality of Service Command Line Interface Overview, configure Modular QoS by: 1. Defining a traffic class, using the class-map command. 2. Creating a service policy that associates the traffic class with one or more policies using the policy-map command. 3. Attaching the service policy to an interface, using the service-policy command. The configuration of Modular QoS involves the definitions of policies, classes, match statements, and actions and establishing the relationships among them. This section provides a high-level overview of the following components that make up the configuration of Modular QoS using the Modular CB QoS CLI: The Traffic Class or Class-Map definition This is a name, a set of match statements, and a rule for how to apply these rules. Classes can be hierarchically defined. You can define a class in terms of other classes, which enables a user to establish a mix of match-any and match-all rules for a single class. Match Statements These are the different ways that traffic can be mapped to a class. Service Policies These map Classes to QoS Management actions. A service policy maps the class name to a set of actions. More than one service policy can use the same class to define policies. For example, the same class might be managed differently at different interfaces and therefore more than one policy is needed. Actions These are the various QoS traffic management actions that are possible. Attaching a Service Policy to an Interface A service policy must be applied to an interface and traffic direction for it to actually affect traffic. The same service policy can be applied to more than one interface. You apply service policies using the service-policy command, which is a special type of CLI action. Note: You can create a fairly rich and complex set of class, policy, match, and action definitions on a router. However, be advised that a router with many interfaces and many policies could have a very complicated set of definitions for a user to navigate. 6 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

11 Chapter 2: Devices and services Traffic Class A traffic class is a relatively simple concept. All packets that match the criteria in the match statements for a class are members of that class. Each traffic class has a specific name. Note: The ability to refer to the class by name allows it to be used more than once on a router, which is very useful. A traffic class is defined in terms of the following attributes: Class Name A traffic class name is specified using an ASCII string. LMatch Statements These statements determine whether a packet should be considered a member of the class. Match statements specify criteria, and packets contents are compared against those criteria. If a statement s criteria matches the contents of a packet, the match is successful. Match Combination Logic This defines how the match statements are to be processed match-any or match-all. Match-any means the packet is considered to be in the class when any of the class s match statements are successful. Match-all means the packet is considered to be in the class only when all the class s match statements are successful. Match Statement A match statement is a Modular CB QoS CLI command that defines criteria to be tested against the contents of each packet. The following are some of the possible types of match statements: match access-group access group This statement tests packets against a specified access control list (ACL) number. The ACL must have been previously defined. match cos cos-value [cos-value cos-value cos-value] This statement tests each packet s layer 2 Class of Service marking for up to four values. match destination-address mac This statement tests each packet s mac layer destination address. match input-interface interface-name This statement tests for the interface of the router that the packet entered. match ip dscp ip-dscp-value [dscp-value (up to 8 values possible)] This statement tests the DSCP (DiffServ Control Point)of an IP (Internet Protocol) packet. You can include up to eight DSCP values in the match statement. Values can range from 0 to 63. match ip precedence ip-precedence-value [ip-precedence value (up to 4 values possible)] This statement tests the IP Precedence of an IP packet. You can include up to four precedence values in the match statement. Values can range from 0 to 7. match ip rtp starting-point port-range This statement matches RTP (Real-Time Transport Protocol) packets whose port range is between startingpoint and starting-point+port-range. match mpls experimental number This statement matches Multiprotocol Label Switching (MPLS) packets whose EXP field equals number. match protocol protocol This statement tests for the protocol of a packet. Among the possible values of protocol are ip, ipx, arp, decnet, vines. IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 7

12 Chapter 2: Devices and services match qos-group qos-group This statement tests the qos-group of a packet. The meaning of each qosgroup and its numerical value are defined locally on a router. If a packet has been determined to be in a specified qos-group, the match is successful. This is an important match statement option. Class maps previously defined can be used within a new class map. Using this option is the only method of including both match-any and match-all statements in a single traffic class. Service Policy A service policy maps a class to a set of actions. A service policy is implemented with the policy-map Modular CB QoS CLI command. A service policy is defined in terms of the following three attributes: Policy Name A policy name is specified using an ASCII string. Class Name This is the name of the traffic class that is to be part of this policy. Traffic in this class will have the actions of this policy applied to it. Actions These are the QoS traffic management actions. The following section, QoS Actions, provides information about the possible actions that can be taken. One of these actions defines a way to nest service policies. In other words, a policy can be defined hierarchically, which makes it easy to reuse them. QoS Actions The Modular CB QoS CLI can perform the following actions: Specifying a minimum bandwidth Policing Shaping Specifying fair queueing Specifying WRED (Weighted Random Early Detection) Some of the possible Modular CB QoS CLI action commands are as follows: bandwidth {bandwidth-kbps percent percent] This action command sets a minimum bandwidth for the traffic class as a raw value or a percent of overall bandwidth. fair-queue number-of-queues This action command sets a number of queues to be reserved for this class. police bps burst-normal burst-max conform-action action exceed-action action violate-action action This action command specifies the maximum bandwidth to be used by this class. Policing is implemented with a token-bucket algorithm, and these are the parameters for it. queue-limit This action command specifies the maximum length of a queue for this traffic (when WRED is not used). random-detect This action command enables WRED drop policy when the class has a guaranteed bandwidth. set ip dscp 8 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

13 Chapter 2: Devices and services This action command sets the DSCP (DiffServ Control Point) field in the IP Header. It must be between 0 and 63. set ip precedence This action command sets the Precedence field in the IP Header. It must be between 0 and 7. shape {average peak} mean-rate [burst-size [excess-burst-size]] This action command shapes the traffic to the indicated burst rate. service-policy {input output} policy-map-name This action command specifies the name of a service policy, which enables the nesting of service-policies. Multiple policies can be applied within a single policy. Note: Once a service policy is defined, it must be mapped to a network interface using this command. Review of the CISCO-CLASS-BASED-QOS-MIB The CISCO-CLASS-BASED-QOS-MIB is the source of all the metrics reported in the Cisco CBQoS Technology Pack. Specifically, the CISCO-CLASS-BASED-QOS-MIB reports metrics associated with the Modular QoS, including configuration and performance information, as well as traffic counts for each of the service policies applied to an interface. You need to understand the CISCO-CLASS-BASED-QOS-MIB only if you intend to customize or augment the contents of the Cisco CBQoS Technology Pack. Note: The actual data reported for an applied policy depends in part upon the type of actions defined for that policy. The CISCO-CLASS-BASED-QOS-MIB (located in the file named CISCO-CLASS-BASED-QOS-MIB.my) is available at the Cisco web site. The following topics promote an understanding of the CISCO-CLASS-BASED-QOS-MIB: Policy and Object Tables Configuration Tables Performance Tables Policy and Object Tables The policy and object tables provide the keys to obtaining the configurations and performance metrics. With these tables you can learn all the run-time service policies and the hierarchy of their components, including classes, match statements, and actions. You can also learn the indexes needed to get configuration and performance metrics for each of these components. The policy and object tables do the following: Support discovery of all the run-time service policies running on a router. These are the policies that have been attached to an interface and traffic direction. A service policy can be attached to more than one interface and traffic direction. There are unique representations for each of these run-time instances of a service policy. Support discovery of the interfaces and traffic directions associated with each run-time service policy. Special support is provided for the Frame Relay and ATM PVC interfaces. The service policies are attached not only to an interface, but also to a circuit or PVC (Permanent Virtual Circuit). IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 9

14 Chapter 2: Devices and services Provide a description of the hierarchical structure of each of the run-time service policies. The components (that is, the class (or classes), match statements, and actions) are all identified. Provide the appropriate indexes. For each component type, there is an index to learn the component configuration details and an index to retrieve performance metrics. The following policy and object tables are described in more detail in the following sections: cbqosservicepolicytable cbqosinterfacepolicytable cbqosframerelaypolicytable cbqosatmpvcpolicytable cbqosobjectstable The following sections are based on the text provided in the CISCO-CLASS-BASED-QOS-MIB. cbqosservicepolicytable Note: Each entry in this table describes the logical interface to which a given policy map is attached. Depending on the interface and media type, some fields might have meaningful values, and some might not. Please read each individual description. Each entry in this table represents the application or attachment of a service policy to an interface and traffic direction. It is possible for the same service policy to be attached to more than one interface and traffic direction. The reuse of service policies is of great value to a user configuring QoS on a router. There is a unique service policy instance, and therefore a unique cbqospolicyindex for each use of a service policy. Note: The cbqospolicyindex references a unique run-time instance of the service policy. This is to be distinguished from the configuration definition of the service policy. The Cisco CBQoS Technology Pack uses the following objects in the cbqosservicepolicytable: cbqosifindex cbqospolicydirection cbqosinterfacepolicytable The cbqosinterfacepolicytable describes the service policies attached to the main interface and the subinterface. This table represents the mapping of service policies to an interface and traffic direction. There is no information in this table that is not in the cbqosservicepolicytable. However, the indexing of these two tables is different. The cbqosinterfacepolicytable is of interest to users who want to discover the CB QoS service policies based the interface indexes and directions of traffic. The Cisco CBQoS Technology Pack uses the following objects in the cbqosinterfacepolicytable: ifindex cbqospolicydirection 10 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

15 Chapter 2: Devices and services cbqosframerelaypolicytable The cbqosframerelaypolicytable describes the service policies attached to the Frame Relay DLCIs (Data Link Connection Identifiers). The cbqosframerelaypolicytable provides almost the same information as the cbqosinterfacepolicytable. The difference is that the cbqosinterfacepolicytable describes service policies attached to the main and subinterfaces. Like the cbqosinterfacepolicytable, the cbqosframerelaypolicytable represents the mapping of service policies to an interface and direction. Note: The circuit DLCI is required to identify the index of the service policy attached to the DLCI. The cbqosframerelaypolicytable is of interest to users who wants to discover the CB QoS service policies based the interface indexes and directions of traffic. The Cisco CBQoS Technology Pack uses the following objects in the cbqosframerelaypolicytable: cbqospolicydirection ifindex cbqosatmpvcpolicytable The cbqosatmpvcpolicytable describes the service policies attached to an Asynchronous Transfer Mode (ATM) PVC (Permanent Virtual Circuit). The Cisco CBQoS Technology Pack uses the following objects in the cbqosatmpvcpolicytable: cbqospolicydirection ifindex cbqosobjectstable The cbqosobjectstable includes entries for all objects defined using the Modular CB QoS CLI, as described in Review of the Modular CB QoS CLI on page 6: Classes Match Statements Service Policies Actions Each entry represents a run-time instance of what has been configured using the CLI. For example, the same class can be reused in multiple service policies, and the same classes and service policies can be attached to more than one interface and traffic direction. Each attachment to an interface and traffic direction represents a new run-time instance of a service policy. Also, as each service policy is made up of many components classes, actions and match statements all of these will be represented by their own run-time instances. Besides defining every Modular QoS entity, this table also defines the hierarchical relationships among these entities. For example, a match statement is part of a class, and a class is part of a service policy. The hierarchical relationship is defined using the cbqosparentobjectsindex object in each entry. The Cisco CBQoS Technology Pack uses the following objects in the cbqosobjectstable: cbqosconfigindex cbqosobjectsindex IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 11

16 Chapter 2: Devices and services cbqosobjectstype cbqosparentobjectsindex Configuration Tables Configuration tables represent the configuration information associated with the QoS object entries defined in the cbqosobjectstable. There are tables for each type of QoS object, because each object has unique properties. The index for all these tables is cbqosconfigindex, the same index returned in the cbqosobjectstable. The Cisco CBQoS Technology Pack works with the following configuration tables that the CISCO-CLASS- BASED-QOS-MIB supports: cbqospolicymapcfgtable cbqoscmcfgtable cbqosmatchstmtcfgtable cbqosqueueingcfgtable cbqosredcfgtable cbqosredclasscfgtable cbqospolicecfgtable cbqostscfgtable Table 1 briefly describe each of these configuration tables. The Cisco CBQoS Technology Pack maps these table objects to appropriately named Tivoli Netcool Performance Manager properties. The Cisco CBQoS Technology Pack also uses these objects in Discovery formulas.

Specifies configuration information for QoS entry objects of type randomdetect defined in the cbqosobjectstable. Each entry in the cbqosredclasscfgtable table describes configuration information about a WRED action. More specifically, this table holds the IP precedence-based (not the DSCP values-based) WRED configuration parameters. The cbqosredclasscfgtable contains only configuration information and no statistics. Therefore, this table is indexed by the cbqosconfigindex and cbqosredvalue of each WRED action entry. The cbqosredvalue index specifies the IP precedence or IP DSCP (DiffServ Control Point) of the WRED action entry. cbqosredcfgdscpprec cbqosredcfgexponweight cbqosredcfgmeanqsize cbqosredvalue cbqosredcfgmaxthreshold cbqosredcfgminthreshold cbqosredcfgpkgdropprob 14 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

Specifies configuration information for QoS entry objects of type trafficshaping defined in the cbqosobjectstable. Each entry in the cbqostscfgtable table describes configuration information about a traffic-shaping action. Specifically, the table holds such traffic shaping configuration parameters as rate, burst size, and shaping types. The cbqostscfgtable contains only configuration information and no statistics.

20 Chapter 2: Devices and services cbqostsstatstable Object cbqosredclassstatstable Object The Cisco CBQoS Technology Pack uses these objects in SNMP collection formulas. cbqoscmstatstable Object The cbqoscmstatstable specifies statistical information for QoS entry objects of type classmap defined in the cbqosobjectstable. Each entry in the cbqoscmstatstable describes statistical information about a class map. The cbqoscmstatstable includes statistics for all the run-time instances of class maps that are components of service policies defined and attached to interfaces and traffic directions using the Modular CB QoS CLI. Specifically, the table holds such class map statistical information as: Traffic counts prior to any QoS policy actions Dropped traffic counts as the result of any QoS actions (for example, policing, WRED, queueing, and so forth) associated with the class within a service policy Dropped traffic counts due to lack of resources The cbqoscmstatstable contains only statistical information and no configuration information. Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the cbqosservicepolicytable) of each class map entry. These two indexes tie each class map entry to an attached run-time service policy and, therefore, to an interface and traffic direction. The cbqosobjectstable links the run-time class map object to its configuration information and to its place in the hierarchy of QoS objects defined with the Modular CB QoS CLI. The Cisco CBQoS Technology Pack uses the following objects in the cbqoscmstatstable: cbqoscmprepolicybyte64 cbqoscmprepolicypkt64 cbqoscmpostpolicybyte64 cbqoscmdropbyte64 cbqoscmdroppkt64 cbqoscmnobufdroppkt64 The object names have the following meanings: cbqosprepolicy* Objects with this string in their names provide traffic-related metrics that occur prior to applying any QoS policy actions. cbqospostpolicy* Objects with this string in their names provide traffic-related metrics that occur after applying any QoS policy actions. cbqosdrop* Objects with this string in their names provide traffic dropped-related metrics that occur after applying any QoS actions. cbqosnobufdrop* Objects with this string in their names provide traffic dropped-related metrics that occur due to a lack of resources. cbqosmatchstmtstatstable Object The cbqosmatchstmtstatstable specifies statistical information for QoS entry objects of type matchstatement defined in the cbqosobjectstable. Each entry in the cbqosmatchstmtstatstable describes statistical information about a match statement.

Specifically, the table holds such match statement statistical information as packet and byte counter metrics that occur before applying any QoS policy actions. The cbqosmatchstmtstatstable contains only statistical information and no configuration information. Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the cbqosservicepolicytable) of each match statement entry. These two indexes tie each match statement entry to an attached run-time service policy and, therefore, to an interface and traffic direction. The cbqosobjectstable links the run-time match statement object to its configuration information and to its place in the hierarchy of QoS objects defined with the Modular CB QoS CLI. The Cisco CBQoS Technology Pack uses the following objects in the cbqosmatchstmtstatstable: cbqosmatchprepolicybyte64 cbqosmatchprepolicypkt64 cbqospolicestatstable Object The cbqospolicestatstable specifies statistical information for QoS entry objects of type police defined in the cbqosobjectstable. Each entry in the cbqospolicestatstable describes statistical information about a police action.

Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the cbqosservicepolicytable) of each police action entry. These two indexes tie each police action entry to an attached run-time service policy and, therefore, to an interface and traffic direction. The cbqosobjectstable links the run-time police action object to its configuration information and to its place in the hierarchy of QoS objects defined with the Modular CB QoS CLI.

22 Chapter 2: Devices and services Specifically, the table holds such queueing action statistical information as Q depth and discard byte/packet counter metrics. The cbqosqueueingstatstable contains only statistical information and no configuration information. Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the cbqosservicepolicytable) of each queueing action entry. These two indexes tie each queueing action entry to an attached run-time service policy and, therefore, to an interface and traffic direction.

Specifically, the table holds such traffic shaping action statistical information as Q size and delay/drop byte/packet counter metrics. The cbqostsstatstable contains only statistical information and no configuration information. Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the cbqosservicepolicytable) of each traffic shaping action entry.

The cbqosredclassstatstable contains only per precedence/dscp statistical information and no configuration information. Therefore, this table is indexed by the instance-specific IDs cbqosobjectsindex (defined in the cbqosobjectstable) and cbqospolicyindex (defined in the 18 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

23 Chapter 2: Devices and services cbqosservicepolicytable) of each per precedence WRED action entry. These two indexes tie each per precedence WRED action entry to an attached run-time service policy and, therefore, to an interface and traffic direction. The cbqosobjectstable links the run-time per precedence WRED action object to its configuration information and to its place in the hierarchy of QoS objects defined with the Modular CB QoS CLI. In addition to the cbqosobjectsindex and cbqospolicyindex indexes, the cbqosredclassstatstable also provides for an index called cbqosredvalue defined in the cbqosredclasscfgtable. See Configuration Tables on page 12 for more information. The Cisco CBQoS Technology Pack uses the following objects in the cbqosredclassstatstable: cbqosredrandomdropbyte64 cbqosredrandomdroppkt64 cbqosredtaildropbyte64 cbqosredtaildroppkt64 cbqosredtransmitbyte64 cbqosredtransmitpkt64 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 19

25 Chapter 3: Supported reports and This chapter discusses the following topics: Topic Page Overview 21 Reporter sets 21 Reporter set tree 22 Reporter set contents 23 Key performance indicators 41 Overview The Cisco CBQoS Technology Pack supplies a set of reports to display information about the devices and activity associated with the Cisco Class-Based QoS environment. The reports contain metrics that are generated by the formulas that this technology pack provides. The metric names are the same as the names of the formulas that generate them. For information about a metric that is listed for a particular report, see the description of the associated formula in the Collection Formulas section of the IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack Reference. For information about how to navigate to a particular report on the DataView portal, see the NOC Reporting tree in the Subelement Groups section of the IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack Reference. This chapter provides information about deployed reports only. For information about understanding report types, creating reports, configuring reports, viewing and working with reports, and deploying reports, see the IBM Tivoli Netcool Performance Manager DataView User and Administration Guide. This Technology Pack User Guide assumes an understanding of the report-related topics discussed in the IBM Tivoli Netcool Performance Manager DataView User and Administration Guide. Reporter sets A reporter set contains a group of reporters that together provide information about a specific technology or vendor device. Technology pack developers use the Reporter Set Wizard to choose the type of template on which to base the reporter set. Technology packs use reporter sets as the framework for defining reports. The Cisco CBQoS Technology Pack reports display, on a Web portal, the collected information about the devices and technologies that operate in the Cisco Class-Based QoS environment.

47 Chapter 4: Configuring the technology pack This chapter explains how to configure the Cisco CBQoS Technology Pack and consists of the following topics: Topic Page Overview 43 Before you begin 43 Configure the technology pack 44 Losing Indexes After Device Reboots 47 Customizing Discovery Results 47 Overview The Cisco CBQoS Technology Pack is a MIB-based, SNMP pack, and its configuration is relatively straightforward. Before you begin Before configuring the Cisco CBQoS Technology Pack, ensure that you: Have the following software and documentation for your version of Tivoli Netcool Performance Manager: IBM Tivoli Netcool Performance Manager Technology Pack Release Notes for the current technology pack release IBM Tivoli Netcool Performance Manager Installation Guide IBM Tivoli Netcool Performance Manager Technology Pack Installation Guide IBM Tivoli Netcool Performance Manager Upgrade Guide (if you are upgrading the core software) IBM Tivoli Netcool Performance Manager Technology Pack Upgrade Guide (if you are upgrading the technologypack software) IBM Tivoli Netcool Performance Manager DataMart Configuration Guide Important: Refer to this guide to create an inventory profile and initiate a discovery. Access to the Tivoli Netcool Performance Manager DataMart server An X Window server on the DataMart server Note: (Tivoli Netcool Performance Manager ) If there is no graphics card on the DataMart server, you can install the Xvfb virtual frame buffer package to provide X Window services, as described in the IBM Tivoli Netcool Performance Manager Installation Guide. Access to the SilverStream server or Tivoli Intergrated Portal server IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 43

48 Chapter 4: Configuring the technology pack Access to the DataChannel server Have completed the following tasks: Reviewed the release notes for the current technology pack. Important: Release notes contain important information you need to consider before installing a technology pack. They also contain information on specific patches that need to be installed before you configure a technology pack. Installed the current version of the Tivoli Netcool Performance Manager components, as described in the IBM Tivoli Netcool Performance Manager Installation Guide. Installed the Cisco CBQoS Technology Pack. Note: Installation instructions for a technology pack can be found in the IBM Tivoli Netcool Performance Manager Technology Pack Installation Guide. Upgrade instructions for a technology pack can be found in the IBM Tivoli Netcool Performance Manager Technology Pack Upgrade Guide. Localization is done automatically during installation of the technology pack. Configured at least one DataChannel. Configured an SNMP collector subchannel. Created a user on the Cisco Class-Based QoS server with permission to ftp and delete files. Configure the technology pack To configure the Cisco CBQoS Technology Pack, follow these steps: 1. Load the DataMart environment. To load the shell with the DataMart environment, follow these steps: 1-a. Log in to the DataMart server as pvuser. 1-b. Change your working directory to the DataMart home directory (/opt/datamart, by default), using the following command: 1-c. cd /opt/datamart Load the shell with the DataMart environment, by sourcing the datamart.env file, as follows:. /opt/datamart/datamart.env Note: After you load the DataMart environment into the shell, the PVMHOME variable is set to the DataMart home directory, /opt/datamart by default. These instructions assume that this variable has been set. 2. Activate data collection requests. During installation of the technology pack, all predefined data collection requests are promoted to the database and set to inactive (that is, idle displays in the Active column of the Tivoli Netcool Performance Manager DataMart Request Editor). You need to activate these predefined data collection requests using the Request Editor. To set data collection requests to active, follow these steps: 2-a. Change your working directory to $PVMHOME/bin (/opt/datamart/bin, by default) on the DataMart server. 2-b. Invoke the DataMart GUI by entering the following command and pressing Enter: pvm 44 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

49 Chapter 4: Configuring the technology pack 2-c. Click the Configuration tab, then click Request Editor to open the Request Editor. 2-d. Click the Collection tab. 2-e. 2-f. 2-g. Click Refresh. The predefined data collection requests are loaded into the Request Editor from the database. Click the Inactive button in the Filter group box to display only idle requests. In the Sub-Element Groups pane, select all idle data collection requests in the following group or groups: Root->Sub-Element Collect->Cisco CBQoS 2-h. Click the Active box under Details. The Request Editor toggles the idle setting for these data collection requests from idle to active in the Active column. 2-i. Click Save. 3. Merge the technology pack subelement inventory text files. Subelement inventory control rules for the Cisco CBQoS Technology Pack are contained in the file cisco_cbqos_inventory_subelements.txt, which is installed in the following directory on the DataMart server: $PVMHOME/APFiles/cisco_cbqos/datamart/conf You must merge the contents of this file with the file inventory_subelements.txt located in $PVMHOME/conf (by default, /opt/datamart/conf) on the DataMart server: Important: You must perform the following steps on MIB II Technology Pack before you perform them on the Cisco CBQoS Technology Pack To merge the subelement inventory control rules for the Cisco CBQoS Technology Pack, follow these steps: 3-a. Change your working directory to $PVMHOME/conf by entering the following command: cd $PVMHOME/conf 3-b. Copy cisco_cbqos_inventory_subelements.txt to the $PVMHOME/conf directory, by entering the following command: cp $PVMHOME/APFiles/cisco_cbqos/datamart/conf/cisco_cbqos_inventory_subelements.txt. 3-c. Make a backup copy of the inventory_subelements.txt file by entering the following command: cp inventory_subelements.txt inventory_subelements.txt.orig 3-d. Append the contents of cisco_cbqos_inventory_subelements.txt to inventory_subelements.txt, by entering the following command: 3-e. 3-f. cat cisco_cbqos_inventory_subelements.txt >> inventory_subelements.txt Important: Ensure that you use two forward brackets (>>); otherwise, the original contents of inventory_subelements.txt will be overwritten. Perform a diff on the backed-up file and the appended file to ensure that the merge succeeded, as shown in the following example: diff inventory_subelements.txt inventory_subelements.txt.orig Configure the cbqos_object_id_mv.pl script by giving the following commands: dos2unix /opt/datamart/apfiles/cisco_cbqos/datamart/bin/cbqos_object_id_mv.pl > /tmp/temp mv /tmp/temp /opt/datamart/bin/cbqos_object_id_mv.pl IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 45

50 Chapter 4: Configuring the technology pack 3-g. To change the file permissions for the script files, execute these commands: chmod 777 /opt/datamart/bin/cbqos_object_id_mv.pl chmod 777 /opt/datamart/conf/inventoryapppack.sh Note: You must use the above scripts if the ProfileName parameter evaluates to Cisco_QoS. 4. Run the initial SNMP inventory and initiate a discovery. An inventory collects data about the network resources that the technology pack monitors. After you install an SNMP technology pack, you must create an inventory profile using the Inventory Tool Wizard and then initiate a discovery by executing the inventory profile using the Inventory Tool. Running the initial inventory against SNMP objects is an intricate task and unfortunately beyond the scope of this configuration chapter. For instructions on using the Inventory Tool Wizard to create an inventory profile, and the Inventory Tool to execute the inventory profile, see the IBM Tivoli Netcool Performance Manager DataMart Configuration Guide. 5. Deploy reports. After the technology pack installation completes, the rules for the new device are automatically loaded into the database. The inventory process uses those rules to group elements and subelements. You must manually deploy (auto-group) the reports by associating them with groups in the NOC Reporting tree in the DataMart Resource Editor. To deploy the Cisco CBQoS Technology Pack reports, follow these steps: 5-a. Open the Tivoli Netcool Performance Manager DataMart Resource Editor. 5-b. Click the ReportSEGroup tab. 5-c. Move the cursor to the left pane and scroll up to select any group under the SUB-ELEMENTS->NOC Reporting tree. 5-d. Right-click and select the AutoGrouping option from the menu. The AutoGrouping option places the reports in dynamically generated groups created during inventory. 5-e. 5-f. 5-g. Click Yes to continue. Click Close to exit the message box, or click Details to view a description of any errors. Optional: You can also deploy reports on a regular basis by creating a cron entry that makes use of the inventory CLI command and the -reportgrouping option. This option instructs the inventory command to run the report grouping rules and update the deployed reports stored in the database. Report grouping rules must first have been created before this option can be used. For information on creating report grouping rules, see the IBM Tivoli Netcool Performance Manager DataMart Configuration Guide. The following example shows a cron entry that periodically performs the deploy report operation: 0 * * * *. /opt/datamart/datamart.env && inventory -nox -reportgrouping See the IBM Tivoli Netcool Performance Manager Command Line Interface Guide for more information about the inventory command. Verifying resources Use the Tivoli Netcool Performance Manager DataMart Resource Editor to determine whether the technology pack resources (elements, subelements, properties, and so on) were successfully discovered and created in the database during inventory. See the IBM Tivoli Netcool Performance Manager DataMart Configuration Guide for information about using the Tivoli Netcool Performance Manager DataMart Resource Editor. 46 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide

51 Chapter 4: Configuring the technology pack Losing Indexes After Device Reboots After a network device reboot, the CISCO-CLASS-BASED-QOS-MIB must be re-polled to re-establish the following indexes: cbqosconfigindex cbqospolicyindex cbqosobjectsindex This is required because a reboot can cause the order of the Modular Quality of Service (QoS) Command-Line Interface (CLI) (MQC) configuration to differ from the actual configuration order, which is user-driven and unpredictable. Traditionally, MIB persistence is handled by Cisco IOS APIs, which save the index and key information to NVRAM. The data is then retrieved and repopulated after reloading. However, this approach does not work well for the current implementation of the cbqosobjectsindex because of the large amount of information that needs to be saved. An index encoding scheme based on configuration entries instead of operational sequence has been implemented to provide persistent indexes on router reload so that MIB information retains the same set of object values each time that a networking device reboots. You may want to configure networking devices to use the QoS: CBQoS MIB Index Enhancements feature. Customizing Discovery Results The properties of the following subelements are merged with and display as properties of the CB QoS Class Map subelement: CB QoS Queueing Action CB QoS Police Action CB QoS Traffic Shaping Action By modifying the cbqos_object_id_mv.pl script, it is possible to customize the results of the Discovery formulas and to fill in the indexes associated with the QueueID, PoliceID, and ShapeID properties. Edits to the scripts described in the following sections should only be done under the guidance of IBM Professional Services. InventoryAppPack.sh This generic script resides in the $PVMHOME/conf directory. It contains processing logic for a number of technology packs and is configured to perform Cisco QoS-related steps as follows: 1. Determines if the ProfileName, CollectorNumber, and DirProfile parameters are passed to it by InventoryHook.sh. If so, it assigns the parameter values to internal variables. If not, it generates a failure message and exits. 2. Determines if the TaskName parameter evaluates to AfterDiscovery. If not, it generates a failure message and exits. 3. Determines if the ProfileName parameter evaluates to Cisco_QoS. If not, it generates a failure message and exits. 4. Passes the following files to cbqos_object_id_mv.pl: $DirProfile/inventory/subelement_invariant.dat An input file containing index values associated with the QueueID, PoliceID, and ShapeID properties. IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide 47

52 Chapter 4: Configuring the technology pack $DirProfile/inventory/subelement_invariant.dat_mod An output file to which cbqos_object_id_mv.pl writes the results of its index substitution operations. 5. Waits for cbqos_object_id_mv.pl to process the files and generates an appropriate message if cbqos_object_id_mv.pl returns successfully. Otherwise, it generates a failure message and exits. 6. Copies subelement_invariant.dat to a backup file called subelement_invariant.dat.orig. 7. Moves subelement_invariant.dat_mod to a file named subelement_invariant.dat. This overwrites the input file that was backed up in the previous step. cbqos_object_id_mv.pl Located in $PVMHOME/bin, this script reads the input file, performs a substitution procedure, and writes the results to the output file. The substitution procedure assigns index values to the QueueID, PoliceID, and ShapeID properties so that these properties are assigned to the CB_QoS Class Map subelement. It uses the following steps: 1. Determines if the input (subelement_invariant.dat) and output (subelement_invariant.dat_mod) files were passed to it by InventoryAppPack.sh. If not, it generates a failure message and exits. Otherwise, it opens both files for processing. 2. Searches the input file for the strings QueueID, PoliceID, and ShapeID and stores their associated index values in three internal variables. It then searches for the strings <P1>, <S1>, and <Q1> and replaces them with the stored index values. 3. Prints the results to the output file (subelement_invariant.dat_mod). (If no substitution is performed, it prints no results to the output file.) 4. Closes both files and returns the results to InventoryAppPack.sh. 48 IBM Tivoli Netcool Performance Manager Cisco Class-Based QoS Technology Pack User Guide
