Support for Configuring Keep-Alive Time for Virtual Link Extension (vLE)
As part of vLE tracking, each node hosting vLEs sends fabric fast keepalives every one second to every other node that hosts the endpoint of the local vLEs. A local node times out a remote node if a keepalive is not received from the remote node in 3 seconds which is the default vLE tracking timeout.
If a remote node times out, Netvisor ONE brings down the local vLE ports, terminating on the remote node. In some deployments, Netvisor ONE determines a three second times out.
Note that the periodic fast keepalive send frequency remains one second. Only the timeout value adjusts to the configured value.
