A no shutdown command executed on the in-band port to which the trap-target address is bound causes the route to that trap target to be re-added to the route table. When the SNMP trap module is notified of this event, it resends the notifications that were missed while there was no route to the trap-target address.
configure# port 1/1/1 no shutdown # # tools perform log test-event
After the notifications have been replayed the Replay from field indicates n/a because there are no more notifications waiting to be replayed and the Last replay field timestamp has been updated.
