Configuring MAC Information

The MAC Information feature can generate syslog messages or SNMP notifications when MAC
address entries are learned or deleted. You can use these messages to monitor user's leaving or
joining the network and analyze network traffic.
The MAC Information feature buffers the MAC change syslog messages or SNMP notifications in a
queue. The device overwrites the oldest MAC address change written into the queue with the most
recent MAC address change when the following conditions exist:
•
The MAC change notification interval does not expire.
•
The queue has been exhausted.
To send a syslog message or SNMP notification immediately after it is created, set the queue length
to zero.
