Description (partial)

MAC address of any host is not learnt on the directly connected interface
MAC address of the host is learnt in hardware but not software

If a certain port is configured as a fex fabric, and reconfigured back as regular L2 switch ports  this may trigger this issue. System will still recognize the ports as fex fabric port and will stop learning mac address.
