SNMP

Send the SNMP traps, Community “Public” to the NMS Server:

(config)#snmp-server host 192.168.1.1 traps [Public | Private]

If you need to define the VERSION and the COMMUNITY STRING:

(config)#snmp-server host 192.168.1.100 traps version 2c cisco

To define RO and RW COMMUNITY:

(config)#snmp-server community TST-RO ro
(config)#snmp-server community TST-RW rw

Specify the TRAPS TYPE:

(config)#snmp-server enable traps [mac-notification | bgp | pim | ...]
(config)#snmp-server host 192.168.1.100 traps version 2c cisco [mac-notification | bgp | pim | ...]

When the traps contain MAC Address Add/Remove notifications, have in mind the QUANTITY, so control it with:

(config)#mac address-table notification change history-size 150
(config)#mac address-table notification change interval 1800

DO NOT FORGET to ENABLE the CAM notifications in Global Configure mode:

(config)#mac address-table notification change

And to make sure:

#show mac address-table notification change interface Gi3/0/1

MAC Notification Feature is Enabled on the switch

Interface            MAC Added Trap MAC Removed Trap

And apply to the interface to GENERATE A TRAP when something happens:

(config-if)#snmp trap mac-notification change added

If you need to configure some deeper changes, or set timers, they are done within each particular COMMAND/TRAP, so;

(config)#mac address-table notification [more options like INTERVAL...]
