Use the interface ethernet command to create an Ethernet sub-interface and 
enter the corresponding Ethernet sub-interface view.

Use the undo interface ethernet command to remove the specified Ethernet 
sub-interface.

By default, no VLAN is associated to an Ethernet sub-interface.

Note that the VLAN associated with the Ethernet sub-interface of the local device 
must be the same as the VLAN associated to the Ethernet sub-interface of the 
peer device. Otherwise, packets cannot be transmitted properly. A Layer 3 
Ethernet interface can accommodate 1 to 4,096 sub-interfaces.
