Table 18 Port statistics data window entries (Continued)
Entry | Description |
|
|
BB_CreditRecoveryFrameFailure | Number of times more frames were lost during a credit recovery |
| period than the recovery process could resolve. This causes a Link |
| Reset to recover the credits. |
|
|
BB_CreditRecoveryRRDYFailure | Number of times more R_RDYs were lost during a credit recovery |
| period than the recovery process could resolve. This causes a Link |
| Reset to recover the credits. |
|
|
Class 2 Frames In | Number of class 2 frames received by this port. |
|
|
Class 2 Frames Out | Number of class 2 frames transmitted by this port. |
|
|
Class 2 Words In | Number of class 2 words received by this port. |
|
|
Class 2 Words Out | Number of class 2 words transmitted by this port. |
|
|
Class 3 Frames In | Number of class 3 frames received by this port. |
|
|
Class 3 Frames Out | Number of class 3 frames transmitted by this port. |
|
|
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 timeout, 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 decoding. |
| Decoding is from the |
|
|
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 Address | Number of address identifier (S_ID, D_ID) errors. AL_PA equals |
| |
|
|
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 |
| link. If the link is not |
| 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. |
