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.

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.
