Brocade G630 FC Switch wrong port speed

[Stefan_Markovic]

CMK version: Checkmk Enterprise Edition 2.1.0p10
OS version: RHEL 8
Brocade Switch G630
Firmware Version: v8.2.1a

All ports are “Assumed speed: 2 Gbit/s” but inventory shows right speed

Inventory

Discovered services

Is this bug or did I do something wrong ?

Hi @Stefan_Markovic, and thanks for reporting this!
Can you send me the agent output of that host, maybe per direct message?
I saw this some time ago, but was never able to reproduce it.

snmpwalk files are send to @robin.gierse

There are 2 workarounds

Option 1

vim /opt/omd/versions/2.1.0p10.cee/share/check_mk/checks/brocade_fcport
Edit from : if len(if_info) == len(speed_info):
to : if len(if_info) == len(speed_info)-2:
Solusion form Brocade_fcport, Port Summary - General - Checkmk Community

It will show then good speed but will destroy output Brocade 6510 switch in out fabric

Option 2:
Configure discovery rule:

Than we can see good port speed:

But then CheckMK will see it as random network port and not brocade port.

If I click on Manual page for this check type it’s random interface

This way we can’t monitor BBcredits etc.

So both “solutions” are bad. This is why I have asked for help.

This is my ( i guess very ugly ) solution used for the Brocades. It does what we need i think.

I am NOT a programmer at all, so this was pure trial and error “hacking” .

So use it as your very own risk .

I did not have any time to investigate further, so can someone tell me, if the issue is still present in the most recent version of Checkmk?

[Stefan_Markovic]

Yes, it’s still present.

this issue should be fixed in next version brocade_fcport: wrong port speed (checkmk.com)
