Chapter 35 Configuring SNMP

Configuring SNMP

Configuring Community Strings

You use the SNMP community string to define the relationship between the SNMP manager and the

agent. The community string acts like a password to permit access to the agent on the switch. Optionally,

you can specify one or more of these characteristics associated with the string:

• An access list of IP addresses of the SNMP managers that are permitted to use the community string

to gain access to the agent

• A MIB view, which defines the subset of all MIB objects accessible to the given community

• Read and write or read-only permission for the MIB objects accessible to the community

Beginning in privileged EXEC mode, follow these steps to conf

igure a community string on the switch:

Command Purpose

Step 1

configure terminal Enter global configuration mode.

Step 2

snmp-server community string [view

view-name] [ro | rw] [access-list-number]

Configure the community string.

Note The @ symbol is used for delimiting the context

information. Avoid using the @ symbol as part of the

SNMP community string when configuring this command.

• For string, specify a string that acts like a password and

permits access to the SNMP protocol. You can configure one

or more community strings of any length.

• (Optional) For view, specify the view record accessible to the

community.

• (Optional) Specify either read-only (ro) if you want

authorized management stations to retrieve MIB objects, or

specify read-write (rw) if you want authorized management

stations to retrieve and modify MIB objects. By default, the

community string permits read-only access to all objects.

• (Optional) For access-list-number, enter an IP standard access

list numbered from 1 to 99 and 1300 to 1999.
