Usage Guidelines

Usage Scenario

You can run the display port vlan command to view information about interfaces of the VLAN and check whether the VLAN is assigned by the command, protocols, or services. If a fault occurs on an interface, you can locate the fault based on the information about the interface and VLAN.

Prerequisite

A VLAN has been created and the Layer 2 interface has joined the VLAN.

Note

If a lot of VLANs are configured on a device, configuring interface-type interface-number filters the command output. If interface-type interface-number is not configured, excessive output information is displayed, causing either of the following problems:

The displayed information is repeatedly refreshed, causing required information to fail to be obtained.
The system does not respond because of long-time information traverse and search.

Example

# Display information about interfaces that belong to each VLAN on the device.
