NIC speed trouble 1

[Valb]

Hello,

I have 2 identical SCO servers (Compac)
The last time I reboot them one NIC (a 3COM 3C905) doesn't negotiate on 100 Full Duplex on one of the two servers

When I enter ndstat -l, Interface speed indicates "100Mbits/sec"
But when I analyze my interface through the network I can see that it is 10 Mbits/sec Half.

I try to compare the 2 servers (drivers, netconfig screen) but I don't see any differences.

My NICs are in auto-negotiation and my switch is forced in 100/Full.
When I pass my switch's port on Auto, it negotiates at 10/Half.

The Space.c file contains :
short e3H_Media_Override[4] = {
MEDIA_OVERRIDE_DEFAULT,
MEDIA_OVERRIDE_DEFAULT,
MEDIA_OVERRIDE_DEFAULT,
MEDIA_OVERRIDE_DEFAULT
};

What can I do to have my Interface configured in 100Mbit/s Full Duplex ?

Thanks for your Help

Valerie

In the netconfig screen choose the NIC, then go to the Advanced options of the Hardware modification screen.

Hope This Helps, PH.

Unfortunately there is no Advanced option for that NIC in netconfig (

And I haven't understood which part of the driver I have to change to force 100/Full.

And the other think I don't understand is the fact that it works on one server but not on the other one !?!?

Thanks

So both NICs are also identical? Have you tried swapping cables between them? The problem may not be related to the machines themselves, but rather the network wiring.

check the firmware versions, NICs may be the same, but the firmware may be different.

The 3Com series of NIC have always performed solidly with SCO. You should definately have a advanced option.

What about the router? Could it be set wrong?
