Description 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.

Example # Create a sub-interface on Ethernet 1/0.

<Sysname> system-view

[Sysname] interface ethernet 1/0.1

[Sysname-Ethernet1/0.1]
