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,
see the “Port Channel” section in the Dell Networking OS Configuration Guide.
