declared as up. For example, if the required minimum is four, and only three are up, the LAG is
considered down.

Usage
Information
This feature groups two LAGs to work in tandem as a supergroup. 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 more information, refer to the “Port Channel” chapter in the
FTOS Configuration Guide .
