• WordsSent – Number of words sent since last reset.
• WordsReceived – Number of words received since last reset.
• LIPCount – Loop Initialization Primitive Sequence. This primitive sequence
applies only to the arbitrated 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.

Viewing Fibre Channel Initiators
LUN Mapping must be enabled in order for VTrak to recognize a Fibre Channel.
See “Enabling LUN Mapping” on page 277.
