Table 5-5.  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   | 
  | 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   | 
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.  |
