Table 6-5. Port Statistics Data Window Entries (Continued)

Entry	Description
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	Number of bad primitives received by the port.
Errors
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.
