Re: RHEL4U5 and NIC flipping



Yes but if your changing the mac and the device then its not static, its
changing. I need eth0 to always be on the same port (port0) (vlan taggging,
security reasons etc) so when I update/install and port0 is now being
detected as eth1, my network is screwed. I need a way to say  port0 == eth0
no matter what order they are detected in.

ifrename does it, but it requires stopping a bunch of stuff, running it and
then restarting a bunch of stuff. Adding the command into the
/etc/rc.sysinit file doesn't work (the interfaces appear to be already
initialized).

Adding the MACADDR option is supposed to set the mac from what I can tell,
but that isnt the case on rhel 5 on my e1000 nic.

I have a similar problem on the Dell 2950.  I add the HWADDR and change
the DEVICE in /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth1
BOOTPROTO=static
HWADDR=00:13:72:65:DB:29
IPADDR=10.207.52.220
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
