NIC Teaming in SuSE Linux
This change has to be done through console. Running ssh to the box wont' get the job done.
- Create a bonding file, ifcfg-bond0 in /etc/sysconfig/network.
linux880:/etc/sysconfig/network # vi ifcfg-bond0 DEVICE=bond0 IPADDR=172.18.9.97 NETMASK=255.255.255.0 NETWORK=172.18.9.0 BROADCAST=172.18.9.255 STARTMODE=onboot BOOTPROTO=static BONDING_MASTER=yes BONDING_MODULE_OPTS='mode=1 miimon=100 / use_carrier=0' BONDING_SLAVE0=eth0 BONDING_SLAVE1=eth1 |
- Create an ifcfg-ethx file for each interface in the bod. All interfaces should have MASTER and SLAVE definitions.
linux880:/etc/sysconfig/network # vi ifcfg-eth0 DEVICE=eth0 STARTMODE=none BOOTPROTO=static MASTER=bond0 SLAVE=yes USERCTL=no atl880:/etc/sysconfig/network # vi ifcfg-eth1 DEVICE=eth1 STARTMODE=none BOOTPROTO=static MASTER=bond0 SLAVE=yes USERCTL=no |
- Delete the original NIC configuration file ifcfg-eth-id-MACADDRESS, or edit the configuration file to disable it.
- Add the bonding alias to /etc/modprobe.conf.local and /etc/modules.conf so that system knows which one is the bonding file to loaded.
linux880:/# more /etc/modprobe.conf.local # # please add local extensions to this file # alias bond0 bonding linux880: # more /etc/modules.conf alias bond0 bonding options bond0 miimon=100 mode=1 |
- Now restart the network devices: /etc/init.d/network restart
linux880:~ # /etc/init.d/network restart Shutting down network interfaces: bond0 done eth0 device: Broadcom BCM5708 (rev 12) eth1 device: Broadcom BCM5708 (rev 12) Shutting down service network . . . . done Setting up network interfaces: lo lo IP address: 127.0.0.1/8 done eth0 device: Broadcom BCM5708 (rev 12) eth0 Startmode is 'none' skipped eth1 device: Broadcom BCM5708 (rev 12) eth1 Startmode is 'none' skipped bond0 bond0 enslaving interfaces: eth0 eth1 bond0 IP address: 172.18.9.97/24 done Setting up service network . . . . . done |
- Run ifconfig to view the configuration change in network setting. Add it should shows bond0, eth0, eth1 and lo in the configuration.

Can I have an additional bonding ? I mean like having bon0 for eth0 and eth1 and bon1 for eth2 and eth3 ?
Yes, I believe you can. Just need to set up a second bond file for the second teaming. I have never tried it though.
Thanks so much for this. I use openSUSE 11 as a home file server and this is icing on the cake for me! I now have everything I wanted in a server.
