Community Strings (for SNMP version 1 and 2c clients)

Community strings are used to control management access to SNMP version 1 and 2c stations, as well as to authorize SNMP stations to receive trap messages from the switch. You therefore need to assign community strings to specified users, and set the access level.

The default strings are:

•public - Specifies read-only access. Authorized management stations are only able to retrieve MIB objects.

•private - Specifies read-write access. Authorized management stations are able to both retrieve and modify MIB objects.

To prevent unauthorized access to the switch from SNMP version 1 or 2c clients, it is recommended that you change the default community strings.

To configure a community string, complete the following steps:

1.From the Privileged Exec level global configuration mode prompt, type “snmp-server community string mode,” where “string” is the community access string and “mode” is rw (read/write) or ro (read only). Press <Enter>. (Note that the default mode is read only.)

2.To remove an existing string, simply type “no snmp-server community string,” where “string” is the community access string to remove. Press <Enter>.

Console(config)#snmp-server community admin rw

Console(config)#snmp-server community private

Console(config)#

clients, we recommend that you delete both of the default
