perf [option]

Displays performance information for all ports. Refer to the ”Show Perf Command” on page B-56.

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.

 

Table B-13. Show 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.
