Chapter 72 Configuring SNMP
Configuring SNMP
To configure a community string on the switch, perform this task:
Note To disable access for an SNMP community, set the community string for that community to the null
string (do not enter a value for the community string).
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# [no] snmp-server
community string [view view-name] [ro |
rw] [access-list-number]
Configures the community string.
• 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 up to 117 characters.
• (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.
To remove a specific community string, use the
no snmp-server community string global configuration
command.
Step 3
Switch(config)# access-list
access-list-number
{deny | permit} source
[source-wildcard]
(Optional) If you specified an IP standard access list number in
Step 2, 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.
Step 4
Switch(config)# end
Returns to privileged EXEC mode.
Step 5
Switch# show running-config
Verifies your entries.
Step 6
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
