Description (partial)

After reboot, interface(s) are not learning MAC addresses and no traffic is forwarded. Ports are in "connected" state, STP also shows forwarding state (it happens with L2 Access Ports). There are no traces in the log. When moving the devices to other ports, everything works as it should. Issue is observed for the first time, there are no PoE devices connected to those interfaces.

C9200 running 16.11.1
