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

 

 

 

 

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 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

 

 

 

 

identified by AL_PS.

 

 

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.

 

 

Errors

 

 

 

Rx Link Resets

Number of link reset primitives received from an attached

 

 

 

 

device.

 

 

Rx Offline Sequences

Number of offline sequence primitives received by the port.
