vle-create

This command creates virtual link extension tracking. You can execute this command from any fabric node to create a virtual link extension between any two switches in the fabric.

]

name name-string

Specify the name of the VLE.

node1 fabric-node name

Specify the name of VLE node 1.

node-2 fabric-node name

Specify the name of VLE node 2.

node-1-port node-1-port-number

Specify the name of the node-1 port that is part of VLE.

node-2-port node-2-port-number

Specify the name of the node-2 port that is part of VLE.

[tracking|no-tracking]

Enable or disable tracking between VLE ports.

Defaults   None.

Access   CLI

History   Command introduced in Version 2.5.4.

Usage   

Provides a mechanism for link state tracking between two ports of two switches in the same fabric for Virtual Link Extension (VLE). When a VLE is created between two physical ports of two switches, the VLE remains up as long as both physical ports are in the state link up.

When VLE tracking is created on a trunk port, the VLE stays up as long as at least one port in the trunk is link up and the remote port is also up. When the last trunk member goes link down, the VLE is brought down. When you configure VLE tracking on a trunk port, you cannot configure tracking on individual trunk members.

VLE tracking helps achieve VLE high availability on Netvisor nodes and avoid the need on the client side to run LACP for link up/down detection.

Examples  This example shows how create virtual link extension tracking between two ports of two switches with tracking enabled.

CLI network-admin@switch > vle-create name myvle node-1 myfabric node-1-port 56 node-2 yourfabric node-2-port 66 tracking
