 Ethernet interface list including several Ethernet 

interfaces, expressed in the format 

interface-list = { interface-num [ to 

interface-num ] } & < 1-10 >

. 

 specifies a single Ethernet 

interface in the format 

interface-num = { interface-type interface-num | 

interface-name }

, where 

 specifies the interface type, 

 specifies the interface number and 

 specifies the 

interface name. For the respective meanings and value ranges, see the parameters 
in the Port Command chapter.

Use the 

 command to enable the centralized MAC address 

authentication feature on a specified port or globally. Use the 

 command to disable the feature on a specified port or 

globally.

By default, the centralized MAC address authentication feature is disabled on each 
port and globally. 

In System View, if the 

 parameter is not specified, the centralized 

MAC address authentication feature is enabled globally; if the 

parameter is specified, the feature is enabled on the specified interfaces. In the 
Ethernet Port View, the 

 parameter cannot be specified, and you 

can use the command only to enable the feature on the current interface.

Before or after the enabling of the centralized MAC address authentication, you 
can configure related parameters both globally or on the port through their 
respective commands. If the parameters are not configured before enabling this 
feature, then the parameters will be in their default state when it is enabled.

You must first enable the centralized MAC address authentication globally and 
then on the port to make the related configurations on the port effective.

To enable the centralized MAC address authentication feature on port Ethernet 
1/0/1, enter the following:
