Chapter2 Catalyst 6500 Series Switch and ROM Monitor Commands set cam notification
Command Modes Privileged.
Usage Guidelines You can globally disable notifications using the set cam notification disable command, but the other
notification configuration settings will remain configured. The notif ication config uration setti ngs can be
reset using the clear config command. The clear cam notification command can be used to clear the
history log or reset notification counters.
If you set the interval time to 0, the switch will send notifications immediately. There is an impact on
the performance of the switch when you set the interval time to zero (0).
You can configure the switch to generate MAC notification SNMP traps using the set snmp enable
macnotification command. MAC notification SNMP traps are generated even when the history log size
is set to zero (0).
Examples This example shows how to enable notification when a MAC address change occ urs to the CA M tabl e:

SNMP traps will be sent if 'set snmp trap enable macnotification' has been set.
