Configuring Simple Network Management Protocol

Configuring Community Strings

DETAILED STEPS

 

Command or Action

Purpose

Step 1

configure terminal

Enters the global configuration mode.

 

Example:

 

 

Switch# configure terminal

 

Step 2 snmp-server community string

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

Example:

Switch(config)# snmp-server community comaccess ro 4

Step 3 access-listaccess-list-number {deny

permit} source [source-wildcard]

Example:

Switch(config)# access-list 4 deny any

Step 4

end

Example:

Switch(config)# end

Configures 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-name, 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.

(Optional) If you specified an IP standard access list number in Step 2, then create the list, repeating the command as many times as necessary.

•For access-list-number, enter the access list number specified in Step 2.

•The deny keyword denies access if the conditions are matched. The permit keyword permits access if the conditions are matched.

•For source, enter the IP address of the SNMP managers that are permitted to use the community string to gain access to the agent.

•(Optional) For source-wildcard, enter the wildcard bits in dotted decimal notation to be applied to the source. Place ones in the bit positions that you want to ignore.

Recall that the access list is always terminated by an implicit deny statement for everything.

Returns to privileged EXEC mode.
