Product Manual Manage with CLU
loop topology. It is transmitted by an L_Port to initialize or re-initialize the loop.
• NOSCount – 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.
• ErrorFrames – 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.
• DumpedFrames – This field specifies the number of frames dumped due to a lack of host buffers.
• LinkFailureCount – Number of times the link has failed. Can be caused by a disconnected link or a bad
fiber element.
• LossSyncCount – Number of times a loss of sync has occurred since last reset.
• PrimitiveSeqErrorCount – 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.
• InvalidWordSentCount – Number of invalid words sent since last reset.
• InvalidCRCCount – Invalid Cyclical Redundancy Count. Number of frames received with an invalid CRC
since last reset.
• InitiatorIOCount – I/O Count on the initiator on the host side.
