On 2950s the eth devices are assigned their number in the wrong order:
Gb1 becomes eth1 (should be eth0) Gb2 becomes eth0 (should be eth1)
Dell posted software that provides a way for the Linux kernel to name the interfaces correctly.
Here is a link to the white paper: http://linux.dell.com/files/whitepapers/nic-enum-whitepaper-v3.pdf

Hi Everyone:
I installed CentOS 4.4 on a new Dell 2950 using the server cd. No errors during the installation and no errors on bootup when loading the Eth0 or Eth1 interfaces. I currently have iptables stopped and selinux disabled. The interfaces have been given a static ip (192.168.1.x). the subnet is 255.255.255.0 and the gateway is 192.168.1.1. I can not ping any device on my network including the gateway. I can ping 127.0.0.1 and the 192.168.1.x. After trying to ping another device ifconfig will show that on ifcfg-lo transmit and receive packets of 389 or some other number depending on how many ping packets were sent. Ifcfg-th0 or Ifcfg-eth1 will not show any TX or RX packets.
The box was ordered to support RH from Dell. The NIC is an embedded dual port Broadcom NetXtreme II5708 GigabitEthernet NIC. I've replaced all network cables and the ports to where they connect into the switch and even a different switch and it still will not show me any love.
There are many issues on the lists.dell.com concerning the broadcom cards. As an example:
http://lists.us.dell.com/pipermail/linux-poweredge/2004-October/thread.html#...
I just checked all my dell servers (I have many) ... but most seem to have intel gigbit NICs.
"Intel Corporation 82541GI/PI Gigabit Ethernet Controller" on most.
Well ... I have this on one machine and it seems to be working OK:
"Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express"
If you use these search terms on google, you will see many issues with broadcom cards on RHEL:
