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
----------------------------------------------10BASE-T yes yes no
10BASE-TFD yes yes no
100BASE-TX yes yes no
100BASE-TXFD yes yes no
1000BASE-X no no no
1000BASE-XFD no no no
1000BASE-T no no no
1000BASE-TFD yes yes no
other no no yes
pause yes no no
Apause yes no no
Spause yes no no
Bpause yes yes noHow can i achieve this with EXOS ?

Hi B-rad,

as you see in the output - auto on speed 10 duplex full was my first shot ...

Are there any advices how i can make debugging more verbose to see why the link does not come up ?

As we did last time, I think we would have to go the GTAC route.

Brad help we via a remote session and getting via interal debug commands (protected via one-time password challenge) to get what the related TP port is advertising and what the partner offers.

Thanks.

Just to circle back, after a remote session, we were able to confirm that the partner device was advertising 10Mfd, 100Mfd, but not 1000Mfd. A feature request was also opened to expose those commands into the standard CLI instead of needing debug mode.

Hello Matthias,

1. To get some info about what the port negotiated, use:
show ports [portlist] configuration no-refresh
show ports [portlist] information detail2. EXOS send any supported speed/duplex mode during autonegotiation, unless configured otherwise. This configuration uses the following command:
configure ports PORTLIST auto on speed SPEED duplex DUPLEXThis supports one setting only, not a set of settings as on EOS.

Best regards,
Erik
