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.

    mac-address-table notification
    snmp-server enable traps mac-notification
    (intf)
    snmp trap mac-notification added|removed

    excellent! That is handy.
