8 2. Getting Start with Web interface 2.1 How to launch: Please firstly set IP according to the following steps before make connection to Internet: Step 1: Prepare a management host which can access IP subnet x or x Step 2: Connect the management host and switch with a suitable cable (See Connectors and Cabling section above) Step 3: Ping (Out-of-band) or (In-band). If fail, make sure Step 1 and 2 are set properly Step 5: Manage the switch through Web,telnet or SNMP interface. This manual illustrates how to manage the switch using a web browser. Step 6: Change In-band and Out-of-band IP to your own proper IP addresses (Refer to section of this manual for more details). Step 7: After Apply and Save To Flash. Reboot (or power off then power on) the switch to make the new IP settings take effect. Important notice: 1. In-band and Out-of-band IPs can t be set to the same domain. 2. The switch doesn t have user name and password by default. Just press Enter key. 3. The SNMP community (read-write) is public by default. 2.2 Login Step 1: Execute browser software of IE 4.0+ or Netscape 4.0+ (IE 5.0/5.0+ is recommended). Step 2: Type in the IP address of in-band or out-of-band connection. Step 3: Fill out boxes of User Name and Password Let s take in-band IP as example: 4

9 Boxes of User Name and Password have been set to null by default, users DO NOT type any character in the boxes if it is the first time to logon the system. In case it is not the first time to logon the system, user should fill out the boxes according to the instructions on Account Description start from section 3.9. Note: In some systems, especially Win2000 with IE5.0 SP2, this authentication box will pop up in each page. To get rid of this inconventient situation, manage the switch with different operation system or different version of IE browser. 5

10 2.3 Welcome Page Welcome page simply gives some important messages for users to get linkage to the information of the company s profile, products and services etc., Enter button leads to the device configurations. Please press Enter button, and get into the Main Page to know the software of this product. 6

11 2.4 Main Page This Main Page consists of three areas; Information Bar, System information and Panel. Explanation will be given one by one as followings: Information Bar On the left side of the Main Page, the bars indicating every main subject of this management system: System, Port, Trunk, IGMP (only support in tagged based VLAN), VLAN, 802.1p, Forwarding DB, Statistics, STP, Reset, and Account. By clicking the + image in front of any of the bars, user can get corresponding submenu for further information. 7

12 2.4.2 Panel This is the front look of the product, please click the switch icon to see the whole picture of the switch. From the front side of the switch, we see different inlets and LED signals. Represents the Ethernet port. Represents the RJ11 Port Speed/Link and Act LED indicator- On the front side of the switch, there are rows of LED indicators displaying each port s transmission speed and active transmissions. For the Ethernet port, 10/100 represent the port is running under 10 or 100 Mbps. Green color represents the port is running under 100 Mbps and dim for 10 Mbps. Act/Link indicates the port is linked and shine for packet transmitting. For RJ 11 (phoneline port), the RJ11 port is force to run under 10 Mbps. There is no speed indicator. The Green light of LINK indicator represent the port is linked up. The ACT indicator will blink green color when there is packet transmitting. User may also click on the phone-jack to enter specific port s configuration page. When out-of-band (console) is connected, the console LED will show steady green. User may modify the panel refresh time on System Configuration page. Click the top-right icon of the panel will hide it. 8

13 2.4.3 System Information Contents Central part of the Main Page shows the system information in eight aspects. This page refreshes every 3 minutes. User must click Apply button after making change on each page to make it effective, some particular functions will not be effective until save to flash and reboot. After press Apply button, please move to Save/Load Settings (a submenu under System) and click Save To Flash button to save the changes in flash memory. If settings are not saved to flash, all new changes will get lost after reboot. 9

14 3 Web Based Management 3.1 SYSTEM The SYSTEM bar directs to the general information and related setting functions of the whole system. After clicking the System bar, concerned submenu will pop up, they are: System Info, System Configure, Port Monitoring, Networking, SNMP, Save /Load Settings and Firmware Upgrade. They are explained one by one as following: 10

15 3.1.1 System Info This page offers the general System Information which includes Device Name, Device Location and Contact person (these three areas can be re-edit.), as well as Device Description, Device Up Time, Product Version, Firmware Version and Hardware Version (these 5 boxes are read only information). To modify system information on this page: 1. Just fill out the top three boxes. 2. Click the Apply button. To make all new changes of the switch taking effect after reboot: 1. Move to Save/Load Settings page. 2. Click the Save To Flash button to make save in the flash memory. Device Name Name of the switch, maximum character length is 255. Device Location, location of the switch, maximum character length is 255. Contact Name of contact person for further help, maximum character length is 255. Device Description Indicates the Model of the device. 11

16 Device Up Time Indicates the device up and running time since last time initiated. Product Version Indicates the Version of the product. Firmware Version Indicates the Version of the current software. Hardware Version Indicates the Version of the current hardware. 12

17 3.1.2 System Configure This System Configuration page allows users to set up functions of the system, such as SuperMac, Aging Control, Aging Time, and Broadcast Storm Control Threshold. It can also set Counter refreshing time and panel (reload applet is a must to make it effective). These settings are operative to the whole device. SuperMac To Enable or Disable the capability of standard backing off the incoming pockets as collision happened. The default setting is Disable. Enable- when collision occurs, the device will use a more aggressive back off algorithm (back off max. 3 time slots), instead of using standard Ethernet back off algorithm. Disable- when collision occurs, the device will perform the IEEE802.3 standard exponential back off algorithm. Aging Control To Enable or Disable the execution of aging the dynamic address learning table entries. The address look up table (Forwarding Database) is set by auto address learning (dynamic) or by manual entry (static). Aging Control is only available to dynamic address learning table entries. When port security mode is set to enable, switch will stop learning new MAC address on that port, and all staic and dynamic MAC addresses that already learned on that port will not be aged out. Enable- makes the aging process be executed to age the dynamic address learning entries. Disable- makes the aging process will not be executed. The default setting is Enable. 13

18 Aging Time Indicates how long source MAC address can stays in address look up table (Forwarding database). The effective value of Aging Time is 0 to 510 seconds. The default setting is 300 seconds. Broadcast Storm Control Threshold This option allows users to limit the number of consecutive broadcast packets transmitted into the switch, the available selections are 16, 32, 48, 64 packets. The default value is 48 packets. Panel Refresh Time Interval (1...60) sec Users can set up the Panel Refresh Time Interval, the effective value is from 1 to 60 seconds and the default setting is 10 seconds. Users have to reload applet after the set up to make it active. Counter Refresh Time Interval (1...60) sec User can set up the Counter Refresh Time Interval, effective value is from 1 to 60 seconds and the default setting is 10 seconds. Users have to reload applet after the set up to make it active. 14

19 3.1.3 Port Monitoring This page allows user to specify a snooping port to do monitoring. Only one monitored port is allowed at one time. Incoming packet flow and Outgoing packet flow can be monitored by different snooping port. Check the Status box of the Monitored Port to enable the function of monitoring both the incoming and outgoing packet flow. Current Monitoring Port Status It displays current Monitoring Port Status, which includes Monitored Port, Incoming Snooping Port, and Outgoing Snooping Port. Monitored Port ID Indicates the port that is being monitored. Snooping Port ID for Incoming packet flow Indicates the Snooping Port to monitor Incoming packet flow of Monitored Port. The default setting is Disable. Snooping Port ID for Outgoing packet flow Indicates the Snooping Port to monitor Outgoing packet flow of Monitored Port. The default setting is Disable. The Snooping Port will have lower efficiency if both Incoming and Outgoing packet snooping are set to it simultaneously. 15

20 3.1.4 Networking There are two interfaces currently being supported (In-Band, Out-of Band) in this management system, users may make selection from them. Out-of-Band is also used as console port. Current Status It shows the setting situations of the current Networking, including MAC Address, IP Address, Subnet Mask, and Default Gateway. Configuration It allows users to configure the IP Address, Subnet Mask and Default Gateway. Users may assign the preferred IP address to the device. IP Address- each time the IP address is changed, users must reset the switch before the new IP address become effective. Subnet Mask- if IP subnet is used, it allows users to enter a subnet mask for the switch. Default gateway- to assign a device default gateway for management use. The default gateway IP is used when the switch is trying to reach a non-local IP Host. 16

21 Set Default Route User must choose either In Band or Out-of Band Default Route as the device s Default Route for transmission management. If switch doesn t know to which interface it should send a packet, it will send the packet to the default route interface. All settings must be saved to flash memory and then do reboot to make them effective SNMP The Simple Network Management Protocol (SNMP) provides the methods to manage and monitor the switch through the Management Information Base (MIB). This page asks users to do the following settings: Set the name of the Community strings Set each Community s access right to be read and write or read only. Set which one as the host to receive SNMP traps To Enable or Disable certain Community SNMP Community Each community under SNMP is set with the condition of Access Right, Trap Receiving, and Status. Community User is asked to give a name to each community (a group nods of management host). Each community have to identify with the Community is used to identify legitimate sources of SNMP requests and the scope limitation also limit the scope of MIB data that can be accessed. Up to four communities can be assigned and enabled in one system. The Maximum character length of the Community String is 12. The Community default is public, its Access Right default is Read-Write, and the Trap receiving default is enable, and the Status default is enable. 17

22 Access Right To set the right of each management host to read-write into the community or to set its right as read-only. Read-Only the management host in the community can perform read function only. Read-Write the management host can perform both read and write functions. Trap Receiving Status Set management host s right to receive SNMP traps. Enable- to enable the Trap receiving right. Disable- to disable the Trap receiving right. Enable or disable the specified Community: Enable- to enable the specified Community. Disable- to disable the specified Community. Users must get valid Community strings before enabling the specified Community. 18

23 Trap Receiving Hosts This Trap Receiving Hosts screen indicates the trap receiving hosts information, maximum number of SNMP Host is six. IP Address This column shows the IP addresses of the management hosts, and enable them to receive the SNMP trap message. Host Name This column indicates the name of the management host, maximum length is 12 characters. Community Status Indicates the name of the community that the management host belongs to. To enable or disable the management function of each management host. Enable- to enable receiving the SNMP trap message. Disable- to disable receiving the SNMP trap message. 19

24 3.1.6 Save Changes/Load Settings All the settings mentioned in this manual are stored only in working memory and will get lost after power off. So, as soon as completing each setting, please press Apply button, then move to Save/Load Settings (a submenu under System) and click Save To Flash to make the settings effective permanently. User can also backup/restore all the settings to/from TFTP server. By saving (backup) all the settings to the TFTP server, user can apply (restore) these settings to other switchs. For switchs that need the same settings, this is an easier way than config them individually. Key in the ip address and port number of TFTP server, then specify the filename on the TFTP server that you are going to save (or load). If access to TFTP server fails, make sure the TFTP server is up and the switch can access it. Note that Backup To TFTP Server does NOT imply Save To Flash, it saves to TFTP server only. Restore And Reboot will read the settings from the file on TFTP server and save these settings to flash (except Networking settings under System menu) then reboot the switch. 20

25 3.1.7 Firmware Upgrade The first step to upgrade the software is to download the new version software file through Internet by web browser or FTP server. The second step is to choose a proper way to upgrade. We have 2 ways for choice to do upgrade operation: 1. HTTP Upgrade: To choose a proper file name on the management host and then click the HTTP Upgrade button. System will complete the upgrade process automatically. 2. TFTP Upgrade: Put the downloaded new version software under a running TFTP server, then specify the TFTP server IP, Port and file name. And then click the TFTP Upgrade button. System will complete the upgrade process automatically. The last step is to reboot the device to finish upgrade process. Upgrade process will cause serious problem if interrupted After the upgrade is completed, it is suggested to reboot the device immediately before modifying any setting otherwise serious problems may occur. Save and load settings are not allowed after successful firmware upgrade. TFTP server software can be found as freeware or shareware on Internet. User can use any one of them. Only networking settings under System menu will remain unchanged after firmware upgrade. Other settings will be set to default value after upgrade. 21

26 3.2 PORT The PORT bar leads to information of main function displays all port status and allows users to set per-port based functions. Moving cursor to the PORT bar, the submenu of All Ports, Port Configure and Port Assigned pop up immediately, user may get further information from them. User may view the current port status, configure individual port or make port assignment (for duplicating settings from one port to other ports) here. 22

27 3.2.1 All Port Status This page shows the current ports regarding linked status, transmission speed and duplex mode. Click the Port ID. to get direct link to the selected port. Port ID. Press the Port ID. Button to get into hyperlink with its Configuring page. Port Name Link Give each port a name for usage convenience, and please limit the character length to 255. This column indicates current link status of each port, Up represents connected Down represents disconnected, while Disabled represents the access status of this port has been set to disable. Speed/Duplex This column shows each port s current transmitting speed of 1 Mbps 23

28 STP Port Status This column represents the port s status in STP (Spanning Tree Protocol), such as forwarding, listening, learning, or blocking (Please get detailed information from STP pages.).whenever shows up in the box of STP Port Status, it indicates Spanning Tree Protocol is disabled. 24

29 3.2.2 Port Configuration This page asks user to characterize the configuration of specified port. By selecting the Port ID number, user may configure the per-port based functions for the selected port. After all settings are done, users must click Apply button to make the setting effective. RJ11 port does not have Full Duplex Flow Control(802.3x), Auto Negotiation and Speed/Duplex configurations. Port Name Give each port a name for use convenience, and please limit the character length to 255. Access Status Enable- to enable the port-access. Transmittion and receiving are allowed on this port. Disable- to disable the port-access. Transmittion and receiving are not allowed on this port. Default setting is Enable. Connectors There are two types of connector on the switch, RJ-11 phone connectors for the HomePNA ports and RJ-45 Ethernet connectors for Ethernet ports. 25

30 Security Through the Security box user may set up security function to the selected port. As the security is set Enable, any security violation packet will be discard. Security violation is defined as any incoming packet without a matched SA (Source MAC Address) on the address table. When security mode is enabled, the port will stop learning new MAC address, all the addresses that already learned by this port will remain exist. Enable- Incoming packet results security violation will be discard. Disable- Any SA of incoming packet is not checked. The default setting is Disable. Address Learning To Enable or Disable the Dynamic Address Learning; Enable- to enable the Dynamic Address Learning. Disable- to disable the Dynamic Address Learning. The default setting is Disable.

The default setting is Enable. Auto Negotiation Enable- Enable the port to do Auto Negotiation about port transmission rate and duplex mode. Disable- Disable the port to have Auto Negotiation function. User has to specify the transmission rate and duplex mode manually. Auto Negotiation will be disabled automatically for fiber interface port. Default setting is Enable. 26

31 Speed/Duplex Indicates the data transmission rate and duplex mode of the selected port. 100/Full- Data is transmitted at 100Mbps in Full-Duplex mode.(both sending and receiving are running at 100Mbps at one time) 10/Full- Data is transmitted at 10Mbps in Full-Duplex mode.(same as above but at 10Mbps) 100/Half- Data is transmitted at 100Mbps in Half-Duplex mode.(only sending or receiving is running at 100Mbps at one time) 10/Half- Data is transmitted at 10Mbps in Half-Duplex mode.(same as above but at 10Mbps). To enable the forcing mode operation, user must disable auto-negotiation. The default value is 100/Full. Broadcast Storm Control Enable- As the Broadcast Storm Control is set enable, the exceeding broadcast packet will be discarded when the number of accumulated broadcast packets surpasses the programmed threshold (set at the system configure submenu). Disable- Broadcast packet will not be throttled. The default setting is Enable. 27

32 3.2.3 Port Assigned Port Assignment gives users a convenient way to duplicate a selected port s settings to other ports. Source Port The source port is the port from which the same setting is to be duplicated to other ports. Target Port Item User may select target ports for setting duplication (other than itself) for port assignment. Click Select All Ports to select all ports and Clear All Ports to clear all ports. There are 7 items to be selected respectively from the Source Port for duplication to assigned ports. 28

33 3.2.4 Port Advance Remark Please do not check with Turbo Speed unless you are using our proprietary HomePNA to Ethernet Converter. 29

34 3.3 Port Based VLAN Vlan (Virtual Local Area Network) basically is a broadcast domain. In a switched network system, a broadcast packet or an unknown destination MAC address packet will broadcast to all, which will decrease the whole network system performance dramatically. By grouping some ports into one VLAN, broadcast packets will only be sent to the ports within that VLAN and without affecting the traffic of outsider ports. This system provides IEEE802.1p priority queue IEEE 802.1q tagged VLAN and Port-based VLAN setting. The default VLAN setting is Port-based VLAN NOTE: IGMP Snooping is only supported in Tag Based VLAN mode. 30

35 3.3.1 Current Status This page shows the current VLAN Status. User can know the VLAN s status. There are Group IP Name and Port Members. 31

36 3.3.2 VLAN Configure User can setup the Port-based VLAN from the form. Group ID the ID of the VLAN group, Total available VLAN Groups number is 128 Status Set the VLAN enable or disable. If the Disable is selected, the VLAN will not establish. Port Members Select the port join the VLAN. User can select the port you want to join the VLAN, remark the port of the number. 32

37 3.3.3 Tag VLAN User can choose Port Based VLAN or Tag Based VLAN mode from this form. If the selection mode is different from the current mode, system will reboot after user click Apply And Reboot button. Reset Back to the current setup. The submenu Port Based VLAN will change to Tag Based VLAN 33

38 3.4 Tag Based VLAN VLAN (Virtual Local Area Network) basically is a broadcast domain. In a switched network system, a broadcast packet or an unknown destination MAC address packet will broadcast to all, which will decrease the whole network system performance dramatically. By grouping some ports into one VLAN, broadcast packets will only be sent to the ports within that VLAN and without affecting the traffic of outsider ports. Any two or more ports can be grouped as one VLAN in the device, overlapping VLAN ports is permitted. Clicking on + in front of VLAN, Current Status and Edit VLAN submenu will be expanded.. NOTE: The IGMP and Tag Based VLAN is displacement. 34

39 3.4.1 Tagged VLAN Configuration Users can set the VLAN group in this page. It supports full 4K VID (VLAN Identification) that defined in 802.1Q. As per the standard, VID 0 and 4095 are reserved and can t be used in real network environment. A port s membership to each VLAN group is dynamically determined by the VID of the tag in a received frame. In tagged VLAN configuration table, there are 4 egress actions on each port to a VLAN group. None- To pass the packet without change. It means if a packet goes into switch with(without) a tag, it will go out this port with(without) a tag. Drop- To drop the packet. All the packets that belong to this VLAN group can t go out from this port. Untag- To untag the packet (if tagged, then untag). All the packets that go out from this port will be untagged. Tag- To tag the packet (if no tagged, then tag with ingress port default VID). If a packet goes into the switch with a tag, it will go out from this port with the original tag. If a packet goes into the switch without a tag, it will go out from this port with a tag that contains the ingress port default VID. Note: 1. Incoming packets with a VID that is not defined in the above table will be dropped. 2. Ingress rule can be assigned in Default VID section. Entry No. The available number of Entry NO. is

40 VID The available number of VID is Add/Del User can add or del the VLAN member. Port assignment User can edit the each port s egress rule to the selected VID. 36

41 3.4.2 VLAN Status This page shows the status of the defined VLAN groups.. 37

42 3.4.3 Default VID Users can setup the VID with Port NO., the available value is and the default Value is 1. If engress filtering rule is enabled, all the untagged packets received on that port will be dropped. 38

43 3.4.4 Tag VLAN User can choose Port Based VLAN or Tag Based VLAN mode from this form. If the selection mode is different from the current mode, system will reboot after user click Apply And Reboot button. Reset Back to the current setup. 39

44 3.5. IGMP This switch uses IGMP (Internet Group Management Protocol) Snooping to monitor for any attached hosts who want to receive a specific multicast service. It looks up the IP Multicast Group used for this service, and adds any port which received a similar request to that group. NOTE: The IGMP and Tag Based VLAN is displacement. 40

45 3.5.1 IGMP Snooping This page allows users to modify IGMP Snooping, Multicast group membership interval, and router ports. When enabled for IGMP snooping, the Switch can open or close a port to a specific multicast group based on IGMP messages passing through the switch. Note: the device support IGMP V.1 and V.2. IGMP Snooping State User can setup the IGMP Snooping State enable or disable. The default value is Disable. Multicast Group Membership Interval User can set up the Counter Refresh Time Interval, effective value is from 30 to and the default setting is 300 seconds. Users have to reload applet after the set up the make it active. Router Ports selection To modify router port, users may select Router Ports selection by clicking the checkbox on the table. As per IGMP standard, only one router will send IGMP request message to a network domain, while other routers just listen to the report messages that send by multicast group members. To make IGMP works correctly on the switch, user must assign the ports that connect to routers. All the IGMP report/leave messages received by the switch will be sent to these router ports. 41

46 3.5.2 IGMP Status Group No. This form shows the IGMP group no. Group IP This form shows the multicast group IP. Multicast Group Member Ports This form shows the member ports that have sent an IGMP report message to the multicast group. This form shows the port with IGMP. 42

47 3.6 IEEE 802.1P Q This system provides IEEE802.1p priority queue and IEEE 802.1q tagged VLAN setting. 43

48 3.6.1 Priority configure Queue Serve Mode There are two ways to select queue serve mode : Strict and Weight Round Robin. Weight (Weight Round-Robin) the weight rule (Q4>Q3>Q2>Q1) When the Weighted Round Robin mode is enabled, each queue is serviced, on the average, the relative integer value of each queue. A higher value means the queue is serviced in higher frequency than the lower value queue. User can configure the queue serve rate in the form, the value is 1~15. Output Queue Management User can set the queue max limit control enable or disable. When enable, frames are dropped on the respective queue when MaxLim is reached. When MaxLim is disabled, frames are kept in the input buffers and input port backpressures once input buffer is full. 44

49 3.6.2 Default Port Priority This page shows the default port priority. User can configure queue of each port, the value is 0~7. A higher value means the queue is serviced in higher frequency than the lower value queue. 45

50 3.7 Forwarding DB Switch will check their address tables (Forwarding Database) before sending data packets to make sure all of the packets are sent correctly. The address table (look up table, forwarding table) can be built by dynamic (automatically) addresses learning or by static (manually) entry. Using dynamic address learning it is possible to age out certain entries if aging time is expired with aging control enable; but it is also keeping updated for new packets with different SA received. All of the static entries shall not be aged out or updated by system itself. The only way to change the Static Entries is through manual editing in the Edit Static Entries page. Moving cursor over the Forwarding DB icon; Current Status, Current Static Entry and Edit Static Entry submenu will pop up. 46

51 3.7.1 Current Forwarding DB Status This screen shows the current Forwarding Database Status. Total 12K MAC entries for tagged VLAN mode or 17K MAC entries for port based VLAN mode can be stored in the forwarding database. Refresh Data Click the Refresh Data button to get the current Forwarding Database of the management system. How many pages can be viewed depends on how many entries are currently existed in the database. Page ID Total 20 pages are available in the management system for the maximum 1024 addresses. Indicates all the ID of the Static and Dynamic Entry. Click on the ID button to sort the table by descending order or click again by ascending order. Port/Trunk/CPU Indicates the Port/Trunk/CPU or Filter of each entry. Click the Port/Trunk/CPU button to sort the table by descending order or click again by ascending order. 47

52 MAC This column indicates the MAC address of each entry. Click on the MAC button to sort the table by descending order or click again by ascending order. Static/Dynamic This column indicates the Static or Dynamic way of entry of each address. Click Static/Dynamic button to sort the table by descending order or click again by ascending order. 48

53 3.7.2 Current Static Entry No This page shows current status of the Static Address Table, which includes Port/Trunk or Filter and the MAC address. Only those activated Static Entries can be shown on this page. This management system supports 256 Explicit static Address Entries, click each Entry s ID can get to the Edit Static Entries page for editing. Port/Trunk MAC This column indicates the port member of each Static Address Entry. This column shows the address of each of the Static Address Entry. Each entry is a six bytes(12 bits) real MAC address. Each Entry must have a unique MAC address in the system. MAC address can t be set to multicast address or broadcast address. 49

54 3.7.3 Edit Static Entries Users can choose a Static Entry to edit its status, as well as port or trunk. Entry ID Status There are 256 Static Entries available in the system, and each Static Entry must have its unique ID number set from figure 1 to 256. Select Each Entry ID may get linkage to its corresponding Static Entry for editing. Enable- activates the selected Static Entry. Disable- inactivates the selected Static Entry. Disabled Static Entry will not be shown on Current Static Entry s page. 50

55 Filter Enable- Packets sent to the specified MAC address will be dropped. Disable- Packets sent to the specified MAC address will be forwarded according to the Port/Trunk Member setting. Port/Trunk Member MAC Users are limited to click only one box either in Port column or Trunk column. Users have to assign a unique and legal MAC address for each static entry for security identification and port selection purpose while transmitting. Different Entries can be assigned with the same Port/Trunk, but the MAC addresses have to be different. 51

56 3.8 STATISTICS Statistics bar leads to statistical contents of each port and host, all figures are reflecting the latest facts since they have been turned on last time. All of the counters are updated every 10 seconds by default. Moving the cursor on the Statistic s bar, submenu of TX/RX Counters, Error Counters, Packet Analysis (TX), Packet Analysis (RX), Packet Attributes, Collision Info, Single Port, and Bar Chart will pop up. Click on each submenu to enter. The counter refresh time interval can be set in Sytem Configuration submenu. 52

67 3.9 Spanning Tree Protocol Spanning Tree Protocol is an IEEE standard for maintaining multiple Ethernet bridges to avoid looping in the network. STP can avoid loops by placing ports in forwarding state or in blocking state to establish redundant paths. This device has the capability to support the Spanning Tree Protocol (802.1d). When the STP is set enabled, the switch will execute STP BPDU packet as below: If the port is in Block-N-Listen State or Learning State, the BPDU packet is forwarded to the CPU, other packets are discarded. If the port is in the Forwarding State, the BPDU packet is forwarded to the CPU, all other packets are normally forwarded based on the switch engine decision. Moving the cursor on the STP icon, submenus of Switch Parameters and Port Parameters will pop up. Click on each submenu to enter. 63

68 3.9.1 Switch Parameters This menu consists of all the 9 setting factors of the Spanning Tree Protocol, they are Spanning Tree Protocol State, Bridge Priority, Designated Root (Root Bridge Priority plus Root Bridge MAC Address), Root Port, Root Path Cost, Bridge Hello Time, Bridge Max Age, and Forward Delay. Spanning Tree Protocol State Enable- activates the Spanning Tree Protocol. Disable- inactivates the Spanning Tree Protocol The default setting is Disable. Enabling the STP will lead to the default VLAN to be enabled. VLAN will lead to the STP to be disabled, vice versa. Disabling the default Bridge Priority Bridge Priority decides whether a bridge in a multi-bridge network is a root bridge or not, lower Bridge Priority induces more chance of Root Bridge. Bridge Priority can be set from 0 to 65535, and the default value is Designated Root This is an identifier to differentiate different roots in the spanning tree, it is used as the Root Identifier in all BPDU originated from this node. Designated Root is formed by Root Bridge Priority combined with Root Bridge MAC address. 64

69 Root Port Contains the port offers the lowest cost path from this bridge to Root Bridge. Root Path Cost Contains the lowest cost that the bridge connects to Root Bridge through Root Port. Bridge Hello Time The time interval between BPDU packets in STP, all of the bridges will send the BPDU packet to elect the Root Bridge periodically. Root Bridge will keep sending the packet to make sure it is still the Root Bridge after been elected. Bridge Hello Time can be from 0 to 10 seconds, default value is set at 2 seconds. Bridge Max Age Bridges will begin to send BPDU packet for electing new Root Bridge if it receive no BPDU packet from Root Bridge after Bridge Max Age expired. Bridge Max. Age ranges from 6 to 40 seconds, the default value is 20 seconds. Forward Delay Forward Delay time determines how long the port changes its STP status from listening/learning to learning/forwarding status. Default Forward Delay is 15 seconds. User can change the Forward Delay time depend on his networking status. 65

70 3.9.2 Port Parameters This menu consists the Priority related setting, Path Cost, Port State and Topology Change Detection. Port No Select a port for configuring spanning trees parameter. Only the leading port of the trunk is shown to represent its role in the spanning tree protocol if the trunk is set. Priority Priority decides which port should be disabled when more than two ports form a loop in a switch, higher priority value means easier disabled. Priority ranges from 0 to 255, and default value is 128. Path Cost Contains the path cost of the port. When more than one port in the switch are connected to Root Bridge with more than one path (through different ports), only the port with lowest Path Cost is active. Path Cost is from 1 to 65535, and the default value is 19. Port State The Port State displays the Spanning Tree Port condition: Blocking- incoming packet will forward to the CPU only if it is a BPDU packet; other packets are discard. 66

71 Listening- acts as Blocking State, it will not forward any packet except the BPDU packet and will try to bring the Learning State as possible. Learning- all source address of the incoming packet except BPDUs will be learned and discard right after. Forwarding- all source address of the incoming packet will be learned and forwarded based on the switch engine decision. 67

72 3.10 RESET Moving the cursor on the RESET bar, the submenu of Reset Counter, Factory Default, and Reboot pop up. Users may reset Counters and Factory Default values on this page. 68

73 Reset Counter Click the Apply button, all counters of the device will be reset to zero Factory Default This page allows users to reload the Factory Default settings and also reboot to make factory default effective. All customer settings (except Networking submenu under System menu) will be erased after reset factory default Reboot Device All changes will be effective after rebooting the device. Users can choose either save the changing result and reboot or reboot the device without saving. After successful firmware upgrade, only Reboot Without Saving button will pop up. 69

74 3.11 ACCOUNT This system provides the basic authentication procedures so as to accomplish security requirements. To the most, seven pairs of user ID and Password are available. Both User ID and Password of factory default are null string. As users enter into the system, we recommended users do add new accounts immediately for security protection. Users will be prompted to type in ID and Password after any account is properly established. Moving the cursor on the Account bar, the submenu of Browse account, Add/Del Account, and Change Password pop up. 70

75 Browse Account This page lists all the valid accounts of the device. Access Level This device divides the accounts into two levels. Power User- Users who gets complete right (read-write) to access the system. Normal User- Users who can only perform read-only operation. 71

76 Add/Del Account The Add/Del Account allows user to add or delete user account. When doing the adding and deleting, user must fill out all the three boxes of User ID, Password, and Access Level. The Maximum length of each of the ID and Password is 32 characters. The first valid account must be the Power User Account. To add a Normal User Account into the system at first time will lead to a Account operation failure. At least one power user must exist in the account. To delete last Power User will lead to a Account operation failure, too. 72

77 Change Password User can only change his own password. It is not allowed to change the Null Account Password. 73
