Overview
Smart link is a switch feature that provides effective, simple and fast-converging link redundancy
in network topology with dual uplink between different layers of the network. It requires an active
(master) and a backup (slave) link. The active link carries the uplink traffic. Upon failure of the
active link, a switchover is triggered and the traffic is directed to the backup link.
