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 users 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 last piece of information written into the queue with the new MAC
address change when the following conditions exist:
The timer set for sending syslog messages or SNMP notifications 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.
The device writes information and sends messages only for the following MAC addresses: dynamic
MAC addresses, MAC addresses that pass MAC authentication, MAC addresses that pass 802.1X
authentication, and secure MAC addresses.
The device does not write information or send messages for blackhole MAC addresses, static MAC
addresses, multiport unicast MAC addresses, multicast MAC addresses, and local MAC addresses.
For more information about MAC authentication, 802.1X, and secure MAC addresses, see Security
Configuration Guide.
