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 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.
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.
• 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.

sends syslog messages to the information center, which then outputs them to the monitoring
terminal. For more information about information center, see Network Management and
Monitoring Configuration Guide.

SNMP notifications to the NMS. For more information about SNMP, see Network Management
