MAC Information Configuration

Overview 
Introduction to MAC Information 
To monitor a network, you need to monitor users joining and leaving the network. Because a MAC 
address uniquely identifies a network user, you can monitor users joining and leaving a network by 
monitoring their MAC addresses.  
With the MAC Information function, Layer 2 Ethernet interfaces send Syslog or trap messages to the 
monitor end in the network when they learn or delete MAC addresses. By analyzing these messages, 
the monitor end can monitor users accessing the network.  
How MAC Information Works 
When a new MAC address is learned or an existing MAC address is deleted on a device, the device 
writes related information about the MAC address to the buffer area used to store user information. 
When the timer set for sending MAC address monitoring Syslog or trap messages expires, or when the 
buffer is used up, the device sends the Syslog or trap messages to the monitor end immediately.
