debug autonegotiation problem

[M_Nees]

We have some clients with gigabit TP NIC on a X450-G2 (EXOS V16.1.3.6 patch1-4) - but they only connect with 100MB full duplex. (i investigate the problem via trial and error)
My concern is now - how can i troubleshoot this from switch CLI?

1) How can i see more what happenend regarding autoneg on that specific port - how can i increase log level to debug this ?
Which log modul have to be modified ?

2) On enterasys Switches (EOS) i could determine via "set port advertise" which speed or duplex modes are advertised to the partner AND which speed / duplex the partner offers.

System(rw)->show port advertise ge.4.36
ge.4.36 capability advertised remote

Doing this by GTAC Case is currently really the only option.

But solving such kind of issues need to be in minutes by some verbose build-in diagnostic commands -
NOT within hours or days by opening a GTAC Case (and doing complicated internal debugs)!

It seems during the last 2 years this topic was not addressed by EXOS Team.

Hi all,

I've a similar case so I think it fits to this case.

Following Situation: If I connect the Printer HP Laserjet M402dn directly to the data socket which is patched to the X450-G2 then the Printer ist not working. But with a D-Link 5 port unmanaged Switch (DGS-105) between Printer and X450 it works. It camed out that if I adjust the Network port on the Printer and X450 to 100 Mbit/s full Duplex than the Printer is available. However the possibilities on the printers Webpage are shown below. It has automatic sense, crossover detection, 10,100 and 1000Mbit/s Connection Speed. May I ask how to find out with Troubleshooting why the X450 and the printer can't auto negotiate with each other? By the way connecting a PC directly to the data socket works.

Update:
The 3rd picture shows some crc errors on command 'show ports rxerrors'. But the counters are not counting on every data packet. Unfortunately I can't find out when it counts up. What could the fault be?

To round up my issue:
I would like to know how to find out what or which thing is the cause for this behavior.
Can anyone help me, please? Thank you in advance.

Are there any chances related to this topic in recent EXOS 22.6 ?

Today one of my customers have a similar problem.
Link to a special measurement device is not going UP. Device should run with 10 MBit/s and Full Duplex.
But this device is running on other switches.
Used Switch X450-G2 - EXOS 22.6-Patch-1-1


I am not able to analyse the problem with the EXOS onboarded debugging (without opening a GTAC Case).

I use this debug commands:

code:

enable log debug-mode
configure log filter DefaultFilter add events vlan.msgs severity debug-data
configure log filter DefaultFilter add events HAL.Port severity debug-data
configure log filter DefaultFilter add events DM.Card severity debug-data
configure log filter DefaultFilter add events HAL.Device severity debug-data
configure log filter DefaultFilter add events HAL.Msg severity debug-data
configure log filter DefaultFilter add events HAL.Transceiver severity debug-data
configure log target console filter DefaultFilter severity Debug-Data

System is connected:

code:

Any suggestions ?

Is the connected device using autonegotiation? If so, use the command "configure port auto on speed 10 duplex full".
