interface interface-type interface-number	Displays the VLAN policy information of a sub-interface with specified interface type and interface number.	interface-type can be Ethernet, GE, or Eth-Trunk.

Usage Guidelines

Usage Scenario

If the same matching policy of VLAN+802.1p, VLAN+DSCP, VLAN+EthType, or untagged+DSCPis configured on different sub-interfaces, you can run the display interface vlan command to view the sub-interfaces. This helps solve the configuration conflict.

Precautions

The display interfacevlan command can be used to display VLAN policy information about all single-tagged or untagged but not double-tagged sub-interfaces of an interface.

Example

# Display all the sub-interfaces tagged with VLAN 1 on GE 1/0/1.

<sysname> display interface GigabitEthernet 0/0/1 vlan 1
