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 fabric login.
	MSB	Continuously increasing offset	x
		Random relative offset	x
		Valid version level	x
		N_Port/F_Port	Must = 1, F_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. The receive buffer field size in the Class 3 parameters is used. The drive uses the lower FS of Fabric
	Login Accept or N_Port Login when sending frames to an initiator.
PN	Port Name. The fabric port name is saved with the login parameters. If a change of the port name is detected during a FAN, an
	implicit logout occurs and a LS_RJT is returned to the fabric.
NN	Node Name. The drive does not check or save the node name.
SO	Service Options—Class 3 only.
	MSB	Class valid	Must = 1
		Intermix	x
		Stacked connection req.	xx
		Sequential delivery	Must = 1
		Other bits reserved	xxx XX
