Determine the level of Fibre Channel standard
The Fibre Channel standard is organized into five levels:
FC-0: The Physical Interface and Media Level handles a variety of physical media and data rates.
FC-1: The Transmission Protocol Level explain the signal encoding technique used for transmission and for synchronization across the point-to-point link.
FC-2: The Framing Protocol Level deals with the transmission of data among ports in the form of frames, same to other data link control protocols.
FC-3: The Common Services Level gives a set of services that are common across multiple ports of a node.
FC-4: The Mapping Level defines the mapping of many channel and network protocols to FC-0 through FC-2.
