display mpls l2vc

Function

The display mpls l2vc command displays information about VPWS connections using the LDP signaling.

Format

display mpls l2vc [ vc-id | state { up | down } ]

Parameters

Parameter	Description	Value
vc-id	Specifies a 32-bit virtual circuit (VC) ID that is locally unique. A combination of the VC ID and VC type uniquely identifies a VC.	The value is an integer ranging from 1 to 4294967295.
state	Displays the status of VCs between peers.	-
up	Displays information about VCs in the Up state.	-
down	Displays information about VCs in the Down state.	-

Usage Guidelines

Usage Scenario

After a VPWS connection is configured or fails, you can use the display mpls l2vc command to view information about the VPWS connection on the device or a specified interface, such as the VC status, AC status, and encapsulation type.

Prerequisites

The basic VPWS function has been configured.

Configuration Impact

If a large number of VPWS connections exist on the device use the regular expression to view specific information about VPWS connections.

Example

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

# Display information about VCs in the Up state between peers.
