Port Replication for Virtual Link Extensions
This feature provides a mechanism for link state tracking between two ports of two switches in the same fabric for Virtual Link Extension (vLE).
When you configure a vLE between two physical ports of two switches, the vLE remains up as long as both physical ports are in the link up state. When you configure vLE tracking on a trunk port, the vLE stays up as long as at least one port in the trunk remains up and the remote port remains up. When the last trunk member goes link down, Netvisor ONE brings down the vLE. Note that 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 ONE nodes and avoids the need on the client side to run LACP for link up/down detection.
Use these commands to create, modify, delete, and show link state tracking:
l vle-create
l vle-modify
l vle-delete
l vle-show
To create virtual link extension tracking, use the vle-create command. You can execute this command from any fabric node to create a virtual link extension between any two switches in the fabric.
CLI network-admin@switch > vle-create name name-string node1 fabric-node name node-2 fabric-node name node-1-port node-1-port-number node-2-port node-2-port-number [tracking|no-tracking]
vle-create
Create virtual link extension tracking
name name-string
Specify the vLE name.
node-1 fabric-node name
Specify vLE node 1 name.
node-2 fabric-node name
Specify vLE node 2 name.

[tracking|no tracking]
Enable or disable tracking between vLE ports
To enable or disable tracking between existing vLE ports, use the vle-modify command:
CLI network-admin@switch > vle-modify name name-string tracking|no tracking
vle-modify
Modify virtual link extension tracking
name name-string
Modify the vLE name
tracking|no tracking
Enable or disable tracking between vLE ports
To delete a virtual link extension, use the vle-delete command:
CLI network-admin@switch > vle-delete name name-string
To view a virtual link extension status, use the vle-show command:
CLI network-admin@switch > vle-show
name node-1 node-2 node-1-port node-2-port status tracking
