configure l2vpn health-check vccv

configure l2vpn [vpls [vpls_name | all] | vpws [vpws_name | all]] health-check vccv {interval interval_seconds} {fault-multiplier fault_multiplier_number}


Configures the Virtual Circuit Connectivity Verification (VCCV) health check test and fault notification intervals for the specified VPLS or VPWS instance.

Syntax Description

vpls_name Identifies the VPLS instance for which health check is to be configured.
vpws_name Identifies the VPWS instance for which health check is to be configured.
all Specifies that the configuration applies to all VPLS instances on the local node.
interval_seconds Defines the interval between health check tests. The range is 1 to 10 seconds.
fault_multiplier_ number Specifies how long health check waits before a warning level message is logged. The wait period is the interval_seconds multiplied by the fault_multiplier_number. The fault_multiplier_number range is 2 to 6.


Interval is 5 seconds.

Fault mulitplier is 4.

Usage Guidelines

The VCCV health-check configuration parameters can be configured at anytime after the VPLS has been created.

The show l2vpn {vpls {{vpls_name} | vpws {{vpws_name}} {peeripaddress} {detail} | summary} command displays the configured interval_seconds and fault-multiplier_number values for the VPLS or VPWS and the VCCV activity state.

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


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

configure vpls myvpls health-check vccv interval 10 fault-notification 40


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 ExtremeXOS and Switch Engine 31.7 Feature License Requirements document.
