Usage Guidelines

Usage Scenario

To view information about interfaces in all VLANs configured on a device, run the display port vlan [ interface-type interface-number ] command. If you want to view information only about interfaces with specified types and numbers in successfully created VLANs, specify active in the preceding command. If a fault occurs on an interface, you can locate the fault based on the information about the interface and VLAN.

Precautions

If a large amount of information about interfaces and VLANs is displayed on a device, specifying an interface when you run the display port vlan command is recommended. Otherwise, the following problems may occur due to excessive output information:

The displayed information is continuously refreshed, and locating desired information is difficult.
The system fails to respond to other requests because it is busy searching information.

Example

The actual command output varies according to the device. The command output here is only an example.
