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, refer to the Port Channel
chapter in the
FTOS Configuration Guide.
