Monitoring CAM changes
This is something that came up at work for which I haven't found an answer to yet. Do any of you know how to get dynamic CAM entries sent to syslog or processed via a trap? Maybe there's an obvious answer in a Cisco doc out there but my Google skills are apparently lacking.

Enable mac-address-table notification globally, enable the mac-notification snmp-trap then enable the snmp traps under the interfaces you want to monitor.

excellent! That is handy."Check both the destination and return path when a route fails." "Switches create a network. Routers connect networks." -
