cam monitor/notification syslogs

Unanswered Question
Apr 4th, 2007

Is there any way to get a syslog message when a cam entry is added instead of the usual snmp trap on a 6500? If I must use snmp does anyone know the specific format of the message? (ie it looks to me like there's 3 bytes prefix and postfix to a list of macs learned????) Setting the logging level of earl (who is earl anyways?) to debug gives me only the "%EARL-7-MAC_NOTIF_SLEEP:Process is going to sleep for the next 15 seconds" messages, but nothing with the actual mac in it.

I have this problem too.
