SNMP Community Strings

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

  • To access a read-only management session using the Web Management Interface, enter the default username (get) and password (public) respectively in the Web.
  • To access a read-write management session using the Web Management Interface, configure a read-write community string using the CLI, and log in using the user name "set" and the read-write community string you configured as the password.

You can configure as many additional read-only and read-write community strings as you need. The number of community strings you can configure depends on the memory on the device. There is no practical limit.

The Web Management Interface supports only one read-write session at a time. When a read-write session is open on the Web Management Interface, subsequent sessions are read-only, even if the session login is “set” with a valid read-write password.

Note: As an alternative to the SNMP community strings, you can secure Web management access using local user accounts or ACLs.
