• NOS Count – Not Operational Primitive Sequence. This primitive sequence
is used during link initialization between two N_Ports in the point-to-point
topology or an N_Port and an F_Port in the fabric topology.
NOS is sent to indicate that the transmitting port has detected a link failure or
is offline. The expected response to a port sending NOS is the OLS primitive
sequence.
• Number of Error Frames – FC devices propagate handshake signals back-
and-forth requesting and acknowledging each byte transferred. FC transfers
occur in one frame of data at a time. In this case, the value reflects the
number of frames with errors.
• Number of Dumped Frames – This field specifies the number of frames
dumped due to a lack of host buffers.
• Link Failure Count – Number of times the link has failed. Can be caused by
a disconnected link or a bad fiber element.
• Loss Sync Count – Number of times a loss of sync has occurred since last
reset.
• Primitive Sequence Error Count – An ordered set transmitted repeatedly
and used to establish and maintain a link.
LR, LRR, NOS, and OLS are primitive sequences used to establish an active
link in a connection between two N_Ports or an N_Port and an F_Port.
LIP, LPB, and LPE are primitive sequences used in the Arbitrated Loop
topology for initializing the loop and enabling or disabling an L_Port.
• Invalid Word Sent Count – Number of invalid words sent since last reset.
• Invalid CRC Count – Invalid Cyclical Redundancy Count. Number of frames
received with an invalid CRC since last reset.
• Initiator IO Count – I/O Count on the initiator on the host side.
