Subject: how to force 10/100 speeds in Linux?

Hi,
My Linux (Redhat 7.2) box has two network cards with built-in
drivers in OS's kernel. One card is 10/100 netgear, and the other is
10/100 cnet.

How can I force the speeds of the two cards at 10Mbps or 100Mbps?
Where can I find the parameter list to do such forcing?

Thanks!

Have a look at :
- mii-tool
- ethtool
depending on your card.

Subject: how to force 10/100 speeds in Linux if both ethtool and mii-tool don't work

Hi,
For one of my machines, both ethtool and mii-tool don't work. Here
are the error messages:

(mii-tool)
SIOCGMIIPHY on 'eth0' failed: invalid argument
.............................................
SIOCGMIIPHY on 'eth7' failed: invalid argument
no MII interfaces found

(ethtool eth0)
setting for eth0:
no data available

I tried some other parameters and go similar results.

What else can we do to force the speed?

What NIC driver are you using?

It is the responsibility of the NIC driver to provide this information.

Subject: mii-tool works - but need compiled again

It seems that my TimeSys OS uses a different library from the standard
Linux. Following Mark Hahn's suggestion, what we need do is to recompile
mii-tool.

Thanks all!
