Description (partial)

Symptom:
Port-channels using LACP will not pass traffic.

Conditions:
After the sup switchover, when doing a show port-channel summary, show interface port-channel XX, show inter ethernet x/x, everything will appear normal and working.

Doing a show lacp interface ethernet x/x, the port will show invalid for LACP, the channel-group will be 0 and also invalid. The port counters for lacp pdu's will not move in the TX or RX direction, hence the device connected to the Nexus will show its member ports in a suspend state.
