Table 28. Port Statistics Data window entries (continued)

Entry	Description
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.
