Default intel card one interface goes offline if forcing to 100/full

I noticed my intel card has two port connected to two different
network through two different switches. I were able to force the eth2
to 100/full using ethtool. However eth3 (the second interface)
disables as shown in `Link detected:' when forcing it to 100/full

default setup up

root@host:~# ethtool eth3
Settings for eth3:

changing it to 100/full from auto

root@host:~# ethtool -s eth3 speed 100 duplex full autoneg off

right away the link light goes off and the interface stops working.

Any idea why it is behaving one second port but not on first port. It
is a dual port card.

Default intel card one interface goes offline if forcing to 100/full

The two switches' respective ports connecting to the dual-port card
may not be set identically, forced to the necessary 100/full, I
suspect.

I had my network engr guy check that and they are both set to
100/full. That is why
I think it is very odd

Maybe silly questions, and bad english.

When you change to "ethtool -s eth3 speed 100 duplex full autoneg off" the link just goes down forever? or is there any communication/activity between the eth3 and the gateway, internet, whatever after 2 or more minutes?


if there isn't communication or even activity that's really odd...perhaps you're using a switch which only supports autoneg and not a fixed speed and duplex or maybe it's just misconfigured?

I have an init.d script on my debian server(etch) and on my PC ubuntu(hardy) which runs everytime they boot up, and both NIC's leds(debian eth0 and eth1) turns off and then get back on in a couple minutes max.

Ubuntu just does the same.
Mine are Intel Corporation 82540EM Gigabit Ethernet Controller and my switch it's a managed 3com gigabit, configured for full duplex 1000Mbps.

Any chance you can reverse them and see if the behaviour follows the
switch port/cables or the eth card ports?

And/or try a new cable on a known good std switch or even a passing
laptop etc....

Have you plugged the cable to the switch which runs the command correctly?
I mean plug the cord into the switch which eth0 and eth1 are plugged in and type in terminal "ethtool -s eth3 speed 100 duplex full autoneg off" and see what happens.
