snmp-server enable traps
SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform
requests for the specified notification types. To specify whether the notifications should be sent as traps
or informs, use the snmp-server host [traps | informs] command.
The snmp-server enable traps command is used in conjunction with the snmp-server host command.
Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send
notifications, you must configure at least one snmp-server host command.
This list of the MIBs is used for the traps:

the community string defined as public:

Switch(config)# snmp-server host myhost.cisco.com public
Switch(config)#
This example shows how to enable the MAC address change MIB notification:
Switch(config)# snmp-server enable traps mac-notification change
Switch(config)#
SNMP traps can be enabled with a rate-limit to detect port-security violations due to restrict mode. The
following example shows how to enable traps for port-security with a rate of 5 traps per second:
Switch(config)# snmp-server enable traps port-security trap-rate 5
Switch(config)#
