Version

XIndicates a four-bit (hex) field is not checked.

x Indicates a single bit is not checked.

BB BB-Credit. This field is not checked. The FC-AL drive uses BB-Credit of zero (0).

CF	Common features. This binary field selects the common features requested by the initiator login.
	MSB	Continuously increasing offset	Must = 1
		Random relative offset	Not checked. Port Login Accept will return a 0—not supported.
		Valid version level	x
		N_Port/F_Port	Must = 0, N_Port
		Alternate credit model	Must = 1
		Other bits reserved	xxx XX
FS	Receive buffer field size. The FS field in the common and Class 3 parameters is checked for the range 128 < FS < 2,112 and a
	multiple of four bytes. For multiple frame sequences, all frames but the last frame of the sequence must be this size. Only the
	receive buffer field size in the Class 3 parameters is used.
PN	Port name (initiator’s)—saved with the login parameters. If a change of the port name/AL_PA address association is detected
	during a Port DISCovery, and implicit logout occurs and the initiator returns a LS_RJT.
NN	Node name. The node name is not checked or saved by the drive.
SO	Service options Class 3 only.
	MSB	Class valid	Must = 1
		Intermix	x
		Stacked connection req.	xx
		Sequential delivery	x
		Other bits reserved	xxx XX
IC	Initiator control
	MSB	XID reassign	xx
		Proc Assc	10 or 11 causes the login to be rejected. Other values are accepted.
		Other bits	XXX
CS	Concurrent sequences		Must be a value greater than 0.
OS	Open sequences per exchange		Must be a value greater than 0.
