Q
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. |
