since you change the MAC address, it's now recognized as a new ethernet device.

... while it still keeps track of the old device.

This situation also happens if you manually replace the NIC on a real
server. I'm not familiar enough with SLES to help you here. Perhaps
there's a menu in yast to delete a network configuration and setup a
new one? For this particular issue you should contact Novell (or at
least fellow SLES/opensuse user) and ask them how to (re)configure
network when you replace an exisiting NIC with a new one.

I'd assume that SLES (like most modern Linux distros) uses udev - in which case look somewhere like /etc/udev/rules.d. In Debian, the network config (MAC <-> I/F mapping) is in a file called <something>persistent-net.rules in that directory.

Just edit this and put the new mac in the line that defines the old eth1, and delete the 'new' NIC. There's probably some means of reloading stuff after this, but rebooting does it for me.

Worst case, try 'grep -ri 00:16:3e:00:00:00 /etc' - putting your old mac address in place of all the zeros.!
