Concept Guide

Usage Information
If you use this command to congure the minimum number of links in a LAG that must be in “oper up” status, 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, the LAG is considered down.
port-channel failover-group
To congure a LAG failover group, access PORT-CHANNEL FAILOVER-GROUP mode.
Syntax

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 trac, avoiding oversubscription on the
other LAG. You can use both static and dynamic (LACP) LAGs to congure failover groups. For more information,
refer to the Port Channel chapter in the Dell Networking OS Conguration Guide.
