First thing to check is if the appropriate kernel support is there.  

cat /proc/interrupts

I guess if ifconfig reports it then it should be loaded.

The next thing to look at is the device set up in

Is it supposed to be doing DHCP from the Cisco?  Your config file should
reflect that.

also look in /var/log/messages to see if there are any comments from the
kernel about eth0.
