What is 'Area Number' in portcfgshow?

Hi,

We recently got a refurbished SAN switch (Brocade 5100 / HP 8/40) and went through the normal check processes on my side.  However, I encountered something I've never seen before - the portcfgshow shows a different area number than the port number.  For instance, the switch showed port 31 but area number 23.  Other switches show port number = area number.

I have not found what area number does in any of the documentation.  Can someone enlighten me as to what are the implications if area number is different from port number?

Hey is it only for that port or it is different for all other ports.

If possible paste the output of 5 ports

Hi,

It seemed to have resolved by itself.  Weird.

The first time I did portcfgshow it had this:

<switch:admin> portcfgshow 31

Area Number:              24

Speed Level:              AUTO(HW)

Fill Word:                0(Idle-Idle)

AL_PA Offset 13:          OFF

Trunk Port                OFF

Long Distance             OFF

VC Link Init              OFF

Locked L_Port             OFF

Locked G_Port             OFF

Disabled E_Port           OFF

Locked E_Port             OFF

ISL R_RDY Mode            OFF

RSCN Suppressed           OFF

Persistent Disable        ON

LOS TOV enable            OFF

NPIV capability           ON

QOS E_Port                AE

Port Auto Disable:        OFF

Rate Limit                OFF

EX Port                   OFF

Mirror Port               OFF

Credit Recovery           ON

F_Port Buffers            OFF

Fault Delay:              0(R_A_TOV)

NPIV PP Limit:            126

CSCTL mode:               OFF

Then I tried to do portcfgshow for every port and it fixed itself.....

<switch:admin> portcfgshow 31

Area Number:              31

Speed Level:              AUTO(HW)

Fill Word:                0(Idle-Idle)

AL_PA Offset 13:          OFF

Trunk Port                OFF

Long Distance             OFF

VC Link Init              OFF

Locked L_Port             OFF

Locked G_Port             OFF

Disabled E_Port           OFF

Locked E_Port             OFF

ISL R_RDY Mode            OFF

RSCN Suppressed           OFF

Persistent Disable        ON

LOS TOV enable            OFF

NPIV capability           ON

QOS E_Port                AE

Port Auto Disable:        OFF

Rate Limit                OFF

EX Port                   OFF

Mirror Port               OFF

Credit Recovery           ON

F_Port Buffers            OFF

Fault Delay:              0(R_A_TOV)

NPIV PP Limit:            126

CSCTL mode:               OFF

This one certainly have me stumped.  I think I'll put it down to a bug in 6.4.2b.

Hi,

My colleague was logged in at the same time .

We resolved it by using the command 'portaddress --bind/unbind'.  Apparently it was bound to another address prior to our use.
