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 non-zero AL_PA found on F_Port.

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 re-establish the link. If the link is not re-established, a link

 

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.
