See Table 37 on page 124 for information about port numbering and mapping.
Decode Error Count Number of invalid transmission words detected during decoding. Decoding is
from the 10-bit characters and special K characters.
Loss Of Sync Count Number of synchronization losses (>100 ms) detected by this port. A loss of
synchronization is detected by receipt of an invalid transmission word.
Invalid CRC Count Number of invalid CRC frames detected.
Tx Wait Count Number of times the port entered a wait state because it was out of buffer-to-
buffer credits.
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 many 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 for a period of time greater than the value of R_T_TOV or by loss
of signal while not in the offline state. A loss of signal causes the switch module
to attempt to reestablish the link. If the link is not reestablished by the time
specified by R_T_TOV, 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 nonprimitive 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.
Total Link Resets Number of link-reset primitives that are transmitted by the port.
Total Offline Sequences Total number of offline sequences transmitted and received by the port.
