Important Points about Shared LAG State Tracking
The following is more information about shared LAG state tracking.
• This feature is available for static and dynamic LAGs.
• Only a LAG can be a member of a failover group.
• You can configure shared LAG state tracking on one side of a link or on both sides.
• If a LAG that is part of a failover group is deleted, the failover group is deleted.
• If a LAG moves to the Down state due to this feature, its members may still be in the Up state.
