Chapter 27 Configuring SNMP
Configuring SNMP
The snmp-server host command specifies which hosts receive the notifications. The snmp-server
enable trap command globally enables the mechanism for the specified notification (for traps and
informs). To enable a host to receive an inform, you must configure an snmp-server host informs
command for the host and globally enable informs by using the snmp-server enable traps command.
To remove the specified host from receiving traps, use the no snmp-server host host global
configuration command. The no snmp-server host command with no keywords disables traps, but not
informs, to the host. To disable informs, use the no snmp-server host informs global configuration
command. To disable a specific trap type, use the no snmp-server enable traps notification-types global
configuration command.
Setting the Agent Contact and Location Information
Beginning in privileged EXEC mode, follow these steps to set the system contact and location of the
SNMP agent so that these descriptions can be accessed through the configuration file:
Step 7 snmp-server trap-source interface-id (Optional) Specify the source interface, which provides the IP address for
the trap message. This command also sets the source IP address for
informs.
Step 8 snmp-server queue-length length (Optional) Establish the message queue length for each trap host. The
range is 1 to 1000; the default is 10.
Step 9 snmp-server trap-timeout seconds (Optional) Define how often to resend trap messages. The range is 1 to
1000; the default is 30 seconds.
Step 10 end Return to privileged EXEC mode.
Step 11 show running-config Verify your entries.
Step 12 copy running-config startup-config (Optional) Save your entries in the configuration file.
