What is cucsFabricSwChPhEpSerial?

This value is the serial number of the peer hardware connected to this specific port. Serial is what an admin records in an RMA request for the exact IOM connected here, rather than guessing which physical unit is misbehaving. For example, a Serial reading FCH1745718Q identifies the exact IOM unit at the other end of this link.
