Usage Guidelines

Usage Scenario

After VLANs are created on a device, you can run the display vlan command to check whether the configuration, name, and status of each VLAN are correct.

Prerequisites

VLANs has been created on a device. Otherwise, no command output is displayed.

Precautions

The following ports are displayed:

Port (Tagged) that labels packets.
Port (Untagged) that does not label packets.
If a large number of VLAN information exists on a device, you are advised to specify the VLAN ID and VLAN name to filter the VLAN information. Otherwise, the following information may be displayed:
The terminal screen keeps refreshing and cannot obtain the required information.
The system does not respond when the system traverses and retrieves the information for a long time.

Example

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