bonding NIC's

Hey guys, i'm a newbie to the forum so go easy on me. I am trying to bond IP Addresses on dual nic'd HP Proliant Blade servers. Anyone know the easiest way to go about this? The servers are running red hat 8.0. Also, if anyone has experience w/ red hat and proliant servers, have you installed insight agent and if so any good sources for that? thanks all!!!

I have never come across this before... I would guess do:
ifconfig eth0 < IP Addreess> broadcast < Broadcast Address > netmask < Subnet Mask >
ifconfig eth0 < IP Addreess> broadcast < Broadcast Address > netmask < Subnet Mask >

with the same IP address... How are you routing this though... You cant set a router to have the same IP address on two different interfaces... At least as far as I know...

hes talking about bonding....

You will need to add at least the following line to /etc/modprobe.conf
so the bonding driver will automatically load when the bond0 interface is
configured. Refer to the modprobe.conf manual page for specific modprobe.conf
syntax details. The Module Parameters section of this document describes each
bonding driver parameter.

alias bond0 bonding

Next you need to configure the contents of /etc/sysconfig/network-scripts/

ifcfg-bond0 should contain the following: (customize for your network)


All interfaces that are part of a bond should have SLAVE and MASTER
definitions. For example, in the case of Red Hat, if you wish to make eth0 and
eth1 a part of the bonding interface bond0, their config files (ifcfg-eth0 and
ifcfg-eth1) should resemble the following:


Use DEVICE=eth1 in the ifcfg-eth1 config file. If you configure a second
bonding interface (bond1), use MASTER=bond1 in the config file to make the
network interface be a slave of bond1.

then commit the bond:

modprobe bonding mode=1 miimon=500

now perform:

service network restart

to restart the interfaces and ensure that the bond is complete

ifconfig should show the successful bond0

check back if that does not do the job for you

to test the bond, unplug one cable, and see if you can still ping, btw the above config is for fault tolerance teaming, not etherchannel or round robin, to do etherchannel or round robing you need to modify your parameters when you modprobe bonding.
