When I have two cables connected and the eth0 interface up and eth1 down, both lights are lit up. In fact, at any point that I have a cable in either interface and the other end is in a switch, they are lit up. But "ifconfig" of course only reports the active eth interface as being up. If I remove the eth0 cable, I lose networking.

As soon as this is activated, networking stops functioning. I can't ping in or out. Am I missing some key step? I know that it works becasue I'm running a firewall on another machine that's running a 2.4.20 kernel and it was autoconfigured and it's functioning properly.
One of the interfaces work and the other not?
Have you tried: a) configuring eth0 only and connect both cables b) ping some external IP: ping IP (don't use -I) c) remove cable from 1st interface c) does the 2sn interface lit up? d) is the ping still working?
It could be a case of a dual ethernet card working as a failover, so if 1st interface works, then the second isn't needed.
This probably happens due to both interfaces being in the same logical and physical net...
