68 Configuring & Monitoring the Switch VH-8G

Setting SNMP Management Access

Access to the VH-8G switch through SNMP is controlled by community

names. The community names set for the switch must match those used

by the SNMP management station for successful communication to

occur. Access for community names can be set to READ/WRITE or

READ ONLY access. The default “Public” community name allows READ

ONLY access to the device via SNMP, whereas the default “Private”

community name allows READ/WRITE access.

The VH-8G switch can send SNMP messages called traps to SNMP

management stations when an important event occurs with the switch.

The switch allows up to five destinations to be configured for these trap

messages to be sent.

To configure SNMP access for the switch, do the following:

1. Select Management Setup Menu from the Main Menu.

2. Select SNMP Configuration Menu.

3. Select SNMP Communities from the menu. Enter the desired

community names (you are permitted to enter from one to 20

characters) and set access to READ/WRITE or READ ONLY.

4. Select IP Trap Managers from the SNMP Configuration Menu.

5. Enter appropriate IP addresses for the Trap destinations.

6. For each Trap destination entered, a corresponding access

community name should be entered.

Viewing Switch Statistics

To view switch statistics, do the following:

1. Select Network Monitor Menu from the Main Menu.

2. Select Port Statistics. Then select the port number to display the

main statistical counts for the port.

3. Select RMON Statistics. Then select the port number to display

detailed statistical counts for the port.

4. On any of the statistics screens, select Reset Counters to clear (zero)

the displayed statistical counts and Refresh Counters to refresh

(update) the displayed statistical counts.
