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.
