Q
Invalid CRC Count Number of invalid Cyclic Redundancy Check (CRC) frames
detected.
Tx Wait Count Number of times the port entered a wait state because it didn't
receive credit to transmit from the attached device.
Class 3 Toss Count Number of class 2 and class 3 sequences that were discarded
by this port. A sequence can be discarded because of
detection of a missing frame (based on SEQ_CNT), detection
of an E_D_TOV timeout, receiving a reject frame, receiving
frames for a stopped sequence, or other causes.
FReject Count Number of frames, from devices, that have been rejected.
Frames can be rejected for any of a large number of reasons.
FBusy Count Number of class 2 and class 3 fabric busy (F_BSY) frames
generated by this port in response to incoming frames. This
usually indicates a busy condition on the fabric or N_port that
is preventing delivery of this frame.
Link Failures Number of optical link failures detected by this port. A link
failure is a loss of synchronization or by loss of signal while not
in the offline state. A loss of signal causes the switch to
attempt to re-establish the link. If the link is not re-established,
a link failure is counted. A link reset is performed after a link
failure.
Primitive Sequence
Errors
Number of bad primitives received by the port.
Rx Link Resets Number of link reset primitives received from an attached
device.
Tx Link Resets Number of link reset primitives sent from this port to an
attached port.
Rx Offline Sequences Number of offline sequence primitives received by the port.
Tx Offline Sequences Number of offline primitives transmitted by the port.
Total Errors Total number of primitive and non-primitive port link errors.
Total Tx Frames Total number of frames transmitted by the port.
Total Rx Frames Total number of frames received by the port.
Total Tx Words Total number of words transmitted by the port.
Total Rx Words Total number of words received by the port.
