> BBCredit Tx | The total number of buffers available for holding Class 2, Class 3 frames to be transmitted to the logged-in Nx_Port. It is for buffer-to-buffer flow control in the direction from FC-Port to Nx_Port. The buffer-to-buffer flow control mechanism is indicated in the respective BbCreditModel.
> CoS | The classes of services that the logged-in Nx_Port has requested the FC-Port to support and the FC-Port has granted the request.
> Class2 RxDataSize | The Class 2 Receive Data Field Size of the logged-in Nx_Port. Specifies the largest Data Field Size for an FT_1 frame that can be received by the Nx_Port.
> Class2 SeqDeliv | Whether the FC-Port has agreed to support Class 2 sequential delivery during the Fabric Login. This is meaningful only if Class 2 service has been agreed. This is applicable only to Fx_Ports.
> Class3 RxDataSize | The Class3 Receive Data Field Size of the logged-in Nx_Port. Specifies the largest Data Field Size for an FT_1 frame that can be received by the Nx_Port.
> Class3 SeqDeliv | Whether the FxPort has agreed to support Class 3 sequential delivery during the Fabric Login. This is meaningful only if Class 3 service has been agreed. This is applicable only to Fx_Ports.
