Chapter 72      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
To set the system contact and location of the SNMP agent so that these descriptions can be accessed 
using the configuration file, perform this task:
Step 5
Switch(config)# snmp-server enable 
traps notification-types
Enables the switch to send traps or informs and specify the type of 
notifications to be sent. For a list of notification types, see Table 72-3 on 
page 72-11, or enter this: snmp-server enable traps ?
To enable multiple types of traps, you must enter a separate snmp-server 
enable traps command for each trap type.
Step 6
Switch(config)# snmp-server 
trap-source interface-id
(Optional) Specifies the source interface, which provides the IP address 
for the trap message. This command also sets the source IP address for 
informs.
Step 7
Switch(config)# snmp-server 
queue-length length
(Optional) Establishes the message queue length for each trap host. The 
range is 1 to 1000; the default is 10.
Step 8
Switch(config)# snmp-server 
trap-timeout seconds
(Optional) Defines how often to resend trap messages. The range is 1 to 
1000; the default is 30 seconds.
Step 9
Switch(config)# end
Returns to privileged EXEC mode.
Step 10
Switch# show running-config
Verifies your entries.
Step 11
Switch# copy running-config 
startup-config
(Optional) Saves your entries in the configuration file.
