Yes, the cable is fine. It is plugged into the switch. I have changed ports also but made no difference.

I have the output of the requested commands attached.

I'm not opening a rar file. You can simply put the output into text.

Sure here it is:

It still sounds like you do not have the correct driver module for this interface.

To select the correct driver package, you should do something like the following:
(The example shows a Realtek, your output should be different)
# /sbin/lspci | grep -i net  

04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)

# /sbin/lspci -n | grep '04:00.0'

04:00.0 0200: 10ec:8168 (rev 01)

By using the Vendor & Device numbers from an ID pairing, you can check to see if your system contains an appropriate driver module for that particular device:
# grep -i 10ec /lib/modules/*/modules.alias | grep -i 8168

If this does not print out a suitable module, then should be your next stop.

Search for the Vendor Device ID pairing of 10ec:8168 on the ElRepo DeviceIDs page will show that kmod-r8168 should work with this particular Ethernet controller. Then go to the download area to retrieve the appropriate binary. There are different binaries for PAE, 32bit, 64bit, etc. so make sure to select the correct one.

Thanks for the feedback however I have already downloaded the latest Broadcom driver for the card I am using from the Broadcom website for RHEL5.4 (bnx2x ver 6) and it made no difference. I downgraded to the current version (ver 5) also just to see if it would make a difference. It originally had ver 4 installed.

In both cases the module installed successfully and could be seen from both the "ethtool -i" command and /librarymodules/<KVER>/drivers/net/bnx2x.ko.
