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.  |
