MLXe chassis showing as MLX (( Netiron ))

VPLS — Thu, 09 Jan 2020 02:08:57 GMT

Hello ,

I have a strange problem , MLXe 4 chassis think it’s MLX Chassis,

I tried upgrading it to different version with no avail ,

telnet@SE-LAB#sh version
System Mode: MLX
Chassis: NetIron 4-slot (Serial #: *******, Part #: *******)
NI-X-HSF Switch Fabric Module 1 (Serial #: ******, Part #: ****)

any way I can fix this identity crisis ?

Send us the output of

show module | include left|right

Here you go

telnet@SE-LAB#sh module | i left
M1 (left ):BR-MLX-MR2-M Management Module Active

I also tried different managment modules (( BR-MLX-MR2-X and MR cards )) with the same result

Are you very sure, that this is a MLXe? Is there a red Brocade logo and a written “Brocade”-label or a white “Extreme”-label and a big white MLXe-4 label on the front?

What is the output of the show chassis command? It shall print out

*** MLXe 4-slot Chassis ***

Also which OS version are you running?

VPLS — Thu, 09 Jan 2020 06:08:16 GMT

Yea Iam very sure , it is hard printed on the chassis MLXe and it was working as MLXe before but now it reads MLX

the current version is 5.7e

Re: MLXe chassis showing as MLX (( Netiron ))

joergkost — Thu, 09 Jan 2020 16:06:13 GMT

Oh, do you mean the line with “System Mode: MLX”?

That is normal, when the system boots up with older linecards and management boards. If you run e.g. the -X line- and management cards only, it will print out “Sysetm Mode: XMR”.

Can you still send the output of show chassis ?

I am more concerned about the chassis line from the version command, it shall read MLXE-4 even in MLX mode. Can you pm me the serial # of the chassis?

VPLS — Sat, 11 Jan 2020 01:37:40 GMT

No Iam not talking about the chassis mode ,

Iam talking about the chassis line it reads Netiron ,

Interesting, while the part number is obvious the MLXe-4 chassis, the serial number is not lookup able from the portal. This is an older device, isn’t it? Like from 2010 or 2011? Maybe it is one of the earlier devices or was once a lab or test device?

Re: MLXe chassis showing as MLX (( Netiron ))

VPLS — Sat, 11 Jan 2020 07:51:27 GMT

yea it is older device ,

we had to pull it out from the datacenter and put it on the lab after it had this identity crisis ,

and Iam trying to figure out if there is a way to force it to act as MLXe-4 again

Re: MLXe chassis showing as MLX (( Netiron ))

joergkost — Sat, 11 Jan 2020 16:51:25 GMT

Did you check the following commands:

dm manu-get

For example on the MLXe-4 it will show something like:

dm manu-get backplane

What is the board-class and chassis type for your device there?

Maybe in the past somebody wrote / changed the identity for this device in the eeprom?

joergkost — Tue, 14 Jan 2020 04:43:56 GMT

Can you run

dm read-chassis-eeprom 2F 1

If it says ,

HEX:
AC

this MLXe may been modified to identify itself as a Netiron XMR. You might recover it by using the dm write-chassis-eeprom 2F counterpart and a crafted hex-string containing a MLXE-4 value to overwrite this one identity byte. However, this is a very special and dangerous command. It can really brick your device, so you should/must ask the official Extreme support or reference to community \at/ extremenetworks.com before any action.

As I guess, that this MLXe has no support contract anymore, they maybe can give you some mercy for this one.

VPLS — Tue, 14 Jan 2020 06:10:24 GMT

Thanks alot , I will open a ticket with extreme , hopefully they will support on this even though the device have no support anymore

Re: MLXe chassis showing as MLX (( Netiron ))

VPLS — Tue, 14 Jan 2020 06:26:59 GMT

also here is the output you requested

telnet@SE-LAB#dm read-chassis-eeprom 2F 1
ASCII:
▒
HEX:
ac
telnet@SE-LAB#

Re: MLXe chassis showing as MLX (( Netiron ))

VPLS — Tue, 14 Jan 2020 07:27:17 GMT

OK extreme refused to suppiort the device as it was out of warranty ,

So I will try my luck and try the command you gave me myself ,

so I should write

dm write-chassis-eeprom 2F fo ?

Re: MLXe chassis showing as MLX (( Netiron ))

joergkost — Tue, 14 Jan 2020 17:52:58 GMT

No, because it is an ASCII string, you will need to find a way to enter f0 as hex character or as a special ascii character, e.g. decimal 240 = hex F0 = ð. It may be possible only via a serial connection. I am also not 100% sure if this is going to fix all your problems, pity Extreme can’t help.

Re: MLXe chassis showing as MLX (( Netiron ))

VPLS — Wed, 15 Jan 2020 02:34:09 GMT

yea I tried to input ð but no way I can type it on putty or MobiXtreme .. do you have any tip I can type ð with ?

Re: MLXe chassis showing as MLX (( Netiron ))

VPLS — Wed, 15 Jan 2020 06:39:12 GMT

I tried Hercules and Termite , and they couldn’t transmit the character either

Re: MLXe chassis showing as MLX (( Netiron ))

joergkost — Wed, 15 Jan 2020 15:59:56 GMT

Ok, the console may be blocking and capturing the non printable characters. Can you try to set the type from the monitor image?

You need to connect a serial console and either interrupt the boot process with the key b or during a booted mlx run the commands:

mlx#dm monitor
Entering Monitor console...
MP-1 OS>set chassis-type
Hexadecimal      0x40=HEAVY, 0x41=LIGHT
MP-1 OS>set backplane-type
Hexadecimal      0x4=mucho, 0x8B=RX-32, 0x84=RX-16, 0x85=RX-8, 0x86=RX-4

If you are lucky,
set chassis-type F0
or set chassis-type 0xF0

will work,

else I am running out of ideas…
