Property Definitions
Definitions of the properties for which statistical information is reported appears in
the list below.
• TimeLastReset – Time in minutes since the system has been running.
• FramesSent – Number of frames sent since last reset.
• FramesReceived – Number of frames received since last reset.
• 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.
