Set Up Community String

Because the SNMP agent provides security by using community strings, you must configure the community string to access any management information base (MIB) in the SNMP managed device's system. Change the community string to limit access to the SNMP managed device's system. To add, modify, and delete community strings, access the SNMP Community String configuration window.

Procedure

Step 1

Select Snmp > V1/V2c > Community String.

Step 2

Select the required server from the Server list box, and then select Find.

Step 3

Perform one of the following tasks:

To add a new community string, click Add New.

Tip

The Add New button does not display in the SNMP Community String Configuration window until you select the Find button. If no community strings exist and you want to add want a community string, select Find and wait for the window to refresh. The Add New button displays.

To modify an existing community string, click the name of the community string that you want to edit from the list of results.

You cannot change the name of the community string or the server.

Step 4

Enter the community string configuration settings.

Tip

Before you save the configuration, you can click the Clear All button at any time to delete all information that you entered for all settings in the window.

Step 5

After you complete the configuration, click Add New to save a new community string or click Save to save changes to an existing community string.

A message indicates that changes will not take effect until you restart the SNMP master agent.

Step 6

Perform one of the following actions:

Select OK to restart the SNMP master agent service and effect the changes.
Select Cancel to continue the configuration without restarting the SNMP master agent.

Note
Cisco recommends that you wait until you finish all the SNMP configuration before you restart the SNMP master agent service.

The system refreshes and displays the SNMP Community String Configuration window. The community string that you created displays in the window.
