Table 5-5. Port Statistics Data Window Entries (Continued)
Entry | Description |
|
|
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. |
LIP(f8,AL_PS) | This LIP denotes a loop failure detected by the L_port identi- |
| fied by AL_PS. |
LIP(f8,f7) | A loop initialization primitive frame used to indicate that a Loop |
| Failure has been detected at its receiver and does not have a |
| valid AL_PA. |
Login Count | Number of device logins that have occurred on the switch. |
Logout Count | Number of device logouts that have occurred on the switch. |
Loop Timeouts | Number of loop timeouts. |
Loss Of Sync | Number of synchronization losses (>100 ms) detected by this |
| port. A loss of synchronization is detected by receipt of an |
| invalid transmission word. |
Primitive Sequence | Number of bad primitives received by the port. |
