Monitor and Debugging LACP

The system log (syslog) records faulty LACP actions.
To debug LACP, use the following command:

Shared LAG State Tracking

Shared LAG State Tracking provides the flexibility to bring down a port channel (LAG) based on the
operational state of another LAG. At any time, only two LAGs can be a part of a group such that the fate
(status) of one LAG depends on the other LAG.
In Figure
Traffic is equally distributed between LAGs 1 and 2. If LAG 1 fails, all traffic from R1 to R4 flows across
LAG 2 only. This condition over-subscribes the link, and packets are dropped.
