enable l2vpn health-check vccv

enable l2vpn [vpls vpls_name | vpws vpws_name] health-check vccv


Enables the VCCV health check feature on the specified VPLS or VPWS.

Syntax Description

vpls_name Identifies the VPLS for which health check is to be enabled.
vpws_name Identifies the VPWS for which health check is to be enabled.


Health check is disabled.

Usage Guidelines

Health check must be enabled on both ends of a PW to verify connectivity between two VPLS or VPWS peers. Both VCCV peers negotiate capabilities at PW setup. A single VCCV session monitors a single PW. Therefore, a VPLS with multiple PWs will have multiple VCCV sessions to multiple peers.

VCCV in ExtremeXOS uses LSP ping to verify connectivity.

The l2vpn keyword was introduced in ExtremeXOS Release 12.4 and is required when enabling health check for a VPWS instance. For backward compatibility, the l2vpn keyword is optional when enabling health check for a VPLS instance. However, this keyword will be required in a future release, so we recommend that you use this keyword for new configurations and scripts.


The following command enables the health check feature on the VPLS instance myvpls:

enable l2vpn vpls myvpls health-check vccv


This command was first available in ExtremeXOS 12.1.

The l2vpn and vpws keywords were first available in ExtremeXOS 12.4.

Platform Availability

This command is available only on the platforms that support MPLS as described in the Switch Engine 32.2 Feature License Requirements document.
