Configured
To troubleshoot a preprovisioned Virtual Chassis configuration that is interconnected
across wiring closets, perform these tasks:

The Virtual Chassis fast failover feature is a hardware-assisted failover mechanism that
automatically reroutes traffic and reduces traffic loss in the event of a link or switch
failure. If a link between two members fails, traffic flow between those members must
be rerouted quickly so that there is minimal traffic loss.
Fast failover is enabled by default on all dedicated Virtual Chassis ports (VCPs).
This example describes how to configure fast failover on uplink module VCPs in a Virtual
Chassis configuration:
