Comparing Trap and Event Messages
Trap and event messages are closely related. Trap messages are a concise form of
event messages. The information that generates trap messages comes from the
same source as the event messages. By configuring a trap, you instruct the router
to automatically send events to the router’s SNMP manager.
To check how your routers are functioning, view the trap messages first; then view
event messages for more detailed information about the routers’ operating status.
