FC-2:
Only FC-2 frames have a header, so these fields are not available for FC-1 frames.
Defines the framing rules and mechanisms for controlling the different service classes. The following building blocks are
defined by the standard:
Ordered Set
Frame
Sequence
Exchange
Protocol
FC-2 Frame Structure
FC-2 Header
The FC-2 header is only 24 bytes long. Header settings do not affect the transmission or reception
of the FC-2 frame.

Understanding the Basic Test Channel Frame Structure
The Fibre Channel standard defines a variable frame length consisting of 36 bytes of overhead and up to 2112 bytes of payload for a
total maximum size of 2148 bytes.
SOF and EOF
A Start of Frame (SOF) delimiter and End of Frame (EOF) delimiter mark the beginning and end of each Fibre Channel
frame
Available for both FC-1 and FC-2 frame formats
Frame Header
Is the first field of the frame content and immediately follows the SOF delimiter and is transmitted on a word boundary
Is used to control link operations and device protocol transfers as well as detect missing or out of order frames
Available in FC-2 frame format only
