Table 5-5. Port Statistics Data Window Entries (Continued)
Entry | Description |
|
|
Class 3 Toss | Number of class 3 frames that were discarded by this port. A |
| frame can be discarded because of detection of a missing |
| frame (based on SEQ_CNT), detection of an E_D_TOV time- |
| out, receiving a reject frame, or receiving a frame on an offline |
| port. |
Class 3 Words In | Number of class 3 words received by this port. |
Class 3 Words Out | Number of class 3 words transmitted by this port. |
Decode Errors | Number of invalid transmission words detected during decod- |
| ing. Decoding is from the |
| acters. |
Ep Connects | Number of E_Port logins. |
FBusy | 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. |
Flow Errors | Number of times a frame is received and all the switch ports |
| receive buffers are full. The normal Fabric Login exchange of |
| flow control credit should prevent this from occurring. The |
| frame will be discarded. |
FReject | Number of frames, from devices, that have been rejected. |
| Frames can be rejected for any of a large number of reasons. |
Invalid CRC | Number of invalid Cyclic Redundancy Check (CRC) frames |
| detected. |
Invalid Destination | Number of address identifier (S_ID, D_ID) errors. AL_PA |
Address | equals |
Link Failures | Number of optical link failures detected by this port. A link fail- |
| ure 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 |
| failure is counted. A link reset is performed after a link failure. |
LIP (AL_PD,AL_PS) | Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets, |
| performed. |
LIP(f7,AL_PS) | This LIP is used to reinitialize the loop. An L_port, identified by |
| AL_PS, may have noticed a performance degradation and is |
| trying to restore the loop. |
LIP(f7,f7) | A loop initialization primitive frame used to acquire an AL_PA. |
