66 CHAPTER 3: P ORT O PERATIONstatistics. The VLAN setting includes permitted VLAN types, and default VLAN ID. Theport setting includes port link type, port speed, and duplex mode. LACP settingincludes 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 IDas the source; if the copy destination is an aggregation group, make theconfigurations of all group member ports identical with that of the source.Displaying andDebugging EthernetPortAfter the above configuration, enter the display command in any view to display therunning of the Ethernet port configuration, and to verify the effect of theconfiguration.Enter the reset command in User View to clear the statistics information of the port.Enter the loopback command in Ethernet Port View to check whether the Ethernetport works normally. In the process of the loopback test, the port cannot forward anypackets. The loop test will finish automatically after a short time.Note that:■ The loopback test cannot be performed on a port disabled by the shutdowncommand. During the loopback test, the system will disable speed, duplex, mdiand shutdown operation on the port. Some ports do not support the loopbacktest. If performing this command in these ports, you will see the system prompt.■ After 802.1X is enabled, the port information cannot be reset.Table 48 Copying Port Configuration to Other PortsOperation CommandCopy portconfiguration toother portscopy configuration source { interface_typeinterface_number | interface_name | aggregation_groupagg_id } destination { interface_list [aggregation_group agg_id ] | aggregation_group agg_id }Table 49 Displaying and Debugging Ethernet PortOperation CommandPerform loopback test on the Ethernetport.loopback { external | internal }Display all port information display interface { interface_type |interface_type interface_num |interface_nam }Display port information of a specific unit display unit unit_id interfaceDisplay hybrid port or trunk port display port { hybrid | trunk }Display the state of loopback detection onthe port.display loopback-detectionClear statistics information of the port reset counters interface [interface_type | interface_typeinterface_num | interface_name ]
