Bonding / Teaming in Ubuntu 12.10

For those who has 4 x Gbe (Intel NIC) configuration with 1 x IPMI network, here is what you can do:

1. Install ifenslave
2. Load up the driver for bonding (will add in info later, check reference link as for now)
3. Locate "interface" /etc/network
4. Change the content accordingly based on this sample:

=============================================

# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback

# Adaptive Load Balancing Teaming

auto eth0

iface eth0 inet manual

bond-master bond0

auto eth1

iface eth1 inet manual

bond-master bond0

auto eth2

iface eth2 inet manual

bond-master bond0

auto eth3

iface eth3 inet manual

bond-master bond0

auto bond0

iface bond0 inet static

address 192.168.0.11

gateway 192.168.0.1

netmask 255.255.255.0

bond-mode balance-alb

bond-miimon 100

bond-slaves eth0 eth1 eth2 eth3

=============================================

• then use command sudo ifdown XXX to bring down all your existing network connection
• next, sudo ifup bond0
• in certain circumstance, you might need to do sudo -s, then bring up all the four Gbe LAN by using ifup eth0, ifup eth1, etc
• to check whether the bonded network loaded up properly, you can go /proc/net/bonding/ and check the bond0
