statistics. The VLAN setting includes permitted VLAN types, and default VLAN ID. The 
port setting includes port link type, port speed, and duplex mode. LACP setting 
includes LACP enabling/disabling.

Perform the following configuration in System View.

Note that if the copy source is an aggregation group, take the port with minimum ID 
as the source; if the copy destination is an aggregation group, make the 
configurations of all group member ports identical with that of the source.

After the above configuration, enter the 

 command in any view to display the 

running of the Ethernet port configuration, and to verify the effect of the 
configuration.

Enter the 

 command in User View to clear the statistics information of the port.

Enter the 

 command in Ethernet Port View to check whether the Ethernet 

port works normally. In the process of the loopback test, the port cannot forward any 
packets. The loop test will finish automatically after a short time.

Note that:

■

The loopback test cannot be performed on a port disabled by the 

command. During the loopback test, the system will disable 

, 

, 

and 

 operation on the port. Some ports do not support the loopback 

test. If performing this command in these ports, you will see the system prompt.

■

After 802.1X is enabled, the port information cannot be reset.
