Usage
Information
This feature groups two LAGs to work in tandem as a supergroup, so that, for example, if one LAG
goes down, the other LAG is taken down automatically, providing an alternate path to reroute traffic,
avoiding oversubscription on the other LAG. You can use both static and dynamic (LACP) LAGs to
configure failover groups. For details, see the Port Channel chapter in the FTOS Configuration Guide.
