Information
If you use this command to configure the minimum number of links in a LAG that must be in “oper up”
status, then the LAG must have at least that number of “oper up” links before it can be declared as up.
For example, if the required minimum is four, and only three are up, then the LAG will be considered
down.

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.
