History   Command introduced in Version 2.5.4.


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 enable tracking on an existing VLE port myvle.

CLI network-admin@switch > vle-modify name myvle tracking
