How Do I Configure the SNMP Community String?
These tasks are used to configure the SNMP community string:
• 4.4.1 Setting Up Nonstandard Community Strings
• 4.4.2 Changing Community Strings Using the Domain Explorer
• 4.4.3 Changing Community Strings Using the CLI
• 4.4.4 Changing Service Level Passwords Using the Domain Explorer
• 4.4.5 Changing the Service Level Passwords Using the CLI
4.4.1 Setting Up Nonstandard Community Strings
The standard community strings are defined as default community strings. If you configure the standard
community strings to a different value, the standard community strings are then defined as nonstandard
community strings.
To set up nonstandard community strings or to change an Service Level password, use the NE
Authentication tab in the Domain Explorer.
Note This method will affect only Cisco MGM. You must make sure that community strings and passwords
within Cisco MGM are in agreement with those on the switches.
Table 4-3 SNMP Configuration Options
Option Description
Domain Explorer,
Network Element
Property pane, NE
Authentication tab
After saving the community strings information, the Cisco MGM processes
use the new community strings for SNMP accesses.
Since users must configure the community strings on both the devices
through CLI, and at the Cisco MGM stations through the Domain Explorer,
there is a possibility of typing in mismatched community strings. This results
in the node with the mismatched community strings either not discovered or
unreachable to Cisco MGM.
Note Configured community strings cannot contain underscore ( _ ) or at
(@) signs. Also, spaces are not allowed in community strings and
Service Level passwords.
SNMP access security Enter the cnfsnmp command on Cisco MGM by using a secured shell to
change the community strings and passwords.
