Port
After the above configuration, execute display command in any view to display 
the running of the Ethernet port configuration, and to verify the effect of the 
configuration.
Execute reset command in user view to clear the statistics information of the port.
The Switch 8800 Family series do not support the Loopback External mode.
When 802.1x is enabled on a port, the statistics information of the port cannot 
be cleared.
By default, the display counters command displays the traffic statistic 
information of all ports in service.
The supported Jumbo frame length ranges, as well as the default values, may 
vary from card to card.

Configuration 
Example
Network requirements
Switch A is connected to Switch B through Trunk port GigabitEthernet2/1/1. 
Configure the Trunk port with default VLAN ID, so that: when receiving the 
packets without VLAN Tag, the port can forward them to the member ports 
belonging to the default VLAN; when it sending the packets with VLAN Tag and 
the packet VLAN ID is the default VLAN ID, the Trunk port remove the packet 
VLAN Tag and forward the packet.
