Version of FC-PH that the F_Port has agreed to support from the fabric login.
N_PtBBCredit
Total number of buffers available for holding a class 1 connect-request, or class 2 or class 3
frames to be transmitted to the attached N_Port. It is for buffer-to-buffer flow control in the
direction from F_Port to N_Port.
N_PtRxDFldSz
Receive data field size of the attached N_Port. This is a binary value that specifies the largest
data field size for an FT_1 frame that can be received by the N_Port. The value is in bytes
ranging from 128 to 2112.
COSSuptAgrd
Flag indicating that the attached N_Port has requested the F_Port for the support of classes
of services and the F_Port granted the request. It’s a bit map of classes of services.
IntrmixSptAgrd
Flag indicating the attached N_Port has requested the F_Port for the support of intermix and
the F_Port has granted the request. This flag is only valid if class 1 service is supported. If the
flag is set at (no) 2, the request is not granted; if set at (yes)1, the request is granted. The
value is always (no) 2.
