Show Command

perf [option]

Displays performance information for all ports. Refer to the Show Perf Command on page B-60.

port [port_number]

Displays operational information for the port given by [port_number]. Ports are numbered beginning with 0. If the port number is omitted, information is displayed for all ports. Table B-13describes the port parameters.

Entry

 

Description

 

 

 

AIinit

 

Incremented each time the port begins AL initialization.

AIinitError

 

Number of times the port entered initialization and the

 

 

initialization failed.

ClassXFramesIn

 

Number of class x frames received by this port.

ClassXFramesOut

 

Number of class x frames sent by this port.

ClassXWordsIn

 

Number of class x words received by this port.

ClassXWordsOut

 

Number of class x words sent by this port.

DecodeError

 

Decoding error detected.

FBusy

 

Number of times the switch sent a F_BSY because Class 2

 

 

frame could not be delivered within ED_TOV time. 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.

Flowerrors

 

Received a frame when there were no available credits.

FReject

 

Number of frames from devices that were rejected.

InvalidCRC

 

Invalid CRC detected.

InvalidDestAddr

 

Invalid destination address detected.

LIP ALPD ALPS

 

Number of F7, AL_PS LIPs, or AL_PD (vendor specific)

 

 

resets, performed.

LIPF7ALPS

 

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.

LIPF8ALPS

 

This LIP denotes a loop failure detected by the L_port

 

 

identified by AL_PS.
