random interfaces on boot

Oscar Erbetta — Tue, 21 Apr 2009 16:16:58 GMT

Hi all,

the problem i have is that i want to create a bonding configuration but my network interfaces appear randomly everytime on boot (on a RHE 5.2), i have 4 eth... and everytime on boot, every NIC appear with a new eth name

i think it can be configured every NIC to an especific eth name interface so it doesn't changes on boot,

thanks for the help

Hi Oscar,

All you need to do is add the 'HWADDR' parameter (MAC definition) to your '/etc/sysconfig/network-scripts/ifcfg-eth*' files (where 'eth*' = eth0, eth1, eth2, eth3):

$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet
DEVICE=eth0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:02:66:F2:F8:D4
IPADDR=209.8.20.13
NETMASK=255.255.255.0
ONBOOT=yes

You can also use udev rules. For example:

# cat /etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:30:48:92:9f:68", NAME="eth0"

Sure, to the right of each person's name (after the date) there should be a Drop-Down menu that lets you assign the number of points to each post. You can assign 0 - 10 per post. Once you have assigned them, click the 'Assign Points' button at the bottom of the page.

Hope this helps! :)
