Title: Change from eth0 to eth1
Post by: vaf on December 07, 2010, 04:04:23 AM

Hi all

I am having a few issues with my server and getting server kernel: NETDEV WATCHDOG: eth0: transmit timed out dropping out the server from the network (which is random and only fixed by rebooting)

I have installed a NIC which has been picked up as eth1 (onboard is eth0)

What is the best way of changing from eth0 to eth1. I am guessing it is not as easy as unplug from in and plug into the other and I haven't found anything in the documentation (possibly not searching for the right terms).

The SME server machine runs 7.5.1 in server mode (not gateway) on about 9mth old hardware.

Thanks

Did you disable the on board nic? If you do, the eth1 should become eth0

I'll try that. If I can't disable the onboard NIC then is there a way to switch them over or something like that?

Thanks

You disable the on board NIC in the BIOS, so SME will not detect it. Every BIOS I have seen has the ability to do this.

Okay I was onsite today, and I disabled onboard ethernet. However during boot-up I got the following error

r8169 device eth0 does not seem to be present, delaying initialization.

r8169 is the onboard device, wherby the PCI NIC is a 3Com card.  The server then has no network access and eth0 is definetly detected:

Output before disabling onboard NIC:
[root@server ~]# /sbin/lspci -m | grep net
03:00.0 "Ethernet controller" "Realtek Semiconductor Co., Ltd."
"RTL8111/8168B PCI Express Gigabit Ethernet controller" -r03 "Giga-byte
Technology" "GA-EP45-DS5 Motherboard"
04:02.0 "Ethernet controller" "3Com Corporation" "3c905C-TX/TX-M
[Tornado]" -r78 "3Com Corporation" "3C905CX-TX/TX-M Fast Etherlink for
PC Management NIC"
 
And after disabling onboard NIC only the 3Com card is there.

How do I get the system to boot and recognise the 3Com as eth0, not to try and find the old eth0?

Thanks

You, you need to log in as admin, and choose option 2. Configure, from the menu.
