Failure Link failure events. N_Port State machine signaling remote has disconnected
or has not responded in time, indicating a problem with the
remote device. This counter is a long-term event counter,
incrementing only once even if the condition persists. A
link failure event occurs when one of the following events
occurs:
• A loss of synchronization.
• Link reset protocol.
• A Not Operational (NOS) primitive sequence is
received.
• A loss of signal occurs in an illegal state.
InvTxWord Instances of link corrup-
tion.
Causes of link corruption follow:
• code violation (invalid transmit word).
• framing error.
• improper beginning running disparity.
LinkTo Expiration of the protocol
timer E_D_TOV during
protocol state change on
the line.
A switch port’s timer may expire if it is much faster than
the remote device. To resolve this speed discrepancy,
either increase the remote device’s speed or increase the
switch time-out period (change the EDTOV setting
through the Ports tab of the Configure Switch dialog box).
LoopConnTO Loop Connection Time
Out.
This counter increments when remote devices do not
acknowledge protocol within the configured time limit.
Time-outs indicate a need to increase the remote device’s
speed. Frequent time-out will definitely affect perfor-
mance.
PrimSeqErr Detected primitive
sequence errors received.
Primitive sequence errors indicate that the remote device is
violating protocol. In most cases the switch port discards
the primitive. If the attached device has done its home-
work, this counter increments very rarely.
PRLIResp Devices on this port that
responded to the PRLI
probe for FC4 Types.

RxClkLoss Loss of receive clock. The switch does not lose receive clock. (This hardware
signal was designed to have an external sync indicator in a
future release.)
