In which case the explanation is simple: By default on a Cisco box, the bridge forwarding database (sho mac addr) timeout is 5 minutes (sho mac addr aging), while the ARP table (ipNetToMedia) hangs around for four hours. Devices down more than 5 minutes but less than four hours will only appear in the ARP table. -- Vincent C. Jones Networking Unlimited, Inc.
