Usage Guidelines

Usage Scenario

To check whether VPWS service configurations are correct when configuring or commissioning VPWS, run the display mpls l2vpn vpws command.

Note the following points when using the display mpls l2vpn vpws command:

If interface interface-type interface-number is specified, only VPWS service information on a specified CE interface is displayed.
If verbose is also specified, detailed information about the VPWS service on a specified CE interface is displayed.

Prerequisites

VPWS has been configured on the local end.

Example

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

# Display the detailed information about the VPWS service on a specified AC interface.
