Secure MAC addresses are special MAC addresses. They never age out or get lost if saved before the 

device restarts. One secure MAC address can be added to only one port in the same VLAN. Thus, you 

can bind a MAC address to one port in the same VLAN.  

Secure MAC addresses can be: 

z 

Learned by a port working in autoLearn mode.  

z 

Manually configured through the command line interface (CLI) or management information base 

(MIB).  

When the maximum number of secure MAC addresses is reached, no more can be added. The port 

allows only packets with the source MAC address being a secure MAC address.  

z 

Enable port security 

z 

Set the maximum number of secure MAC addresses allowed on the port

Set the port security mode to autoLearn 

Follow these steps to configure a secure MAC address: 

Enter system view

Use either approach 

No secure MAC address is 
configured by default. 

 

The configured secure MAC addresses are saved in the configuration file and will not get lost when the 

port goes up or goes down. After you save the configuration file, the secure MAC address saved in the 

configuration file are maintained even after the device restarts.  

 

After an 802.1X user or MAC authenticated user passes RADIUS authentication, the RADIUS server 

delivers the authorization information to the device. You can configure a port to ignore the authorization 

information from the RADIUS server.  

Follow these steps to configure a port to ignore the authorization information from the RADIUS server:
