SNMP community strings

SNMP versions 1 and 2 use community strings to restrict SNMP access.

The community string can be associated with an SNMP group to restrict the access of MIBs for SNMPv1 and SNMPv2c requests. You can configure a total of 256 read-only and read-write community strings on the device.

The software automatically encrypts SNMP community strings. Users with read-only access or who do not have access to management functions in the CLI cannot display the strings. For users with read-write access, the strings are encrypted in the CLI.

By default, you cannot perform any SNMP Set operations until you configure a read-write community string.
