Bonding in SUSE Enterprise Linux

Release:

SUSE Enterprise Linux 10

Problem:

Configure the bond0 interface with the interface eth0 and eth1

Solution:

1)     Create a bond0 interface file in the /etc/sysconfig/network directory.

            # vi /etc/sysconfig/network/ifcfg-bond0

           

            BONDING_MASTER='yes'

            BONDING_MODULE_OPTS='mode=1 miimon=100 use_carrier=0'

            BOOTPROTO='static'

            IPADDR='192.168.10.19'

            NETMASK='255.255.255.0'

            STARTMODE='onboot'

            USERCONTROL='no'

            BONDING_SLAVE0='bus-pci-0000:03:00.0'

            BONDING_SLAVE1='bus-pci-0000:03:00.1'

Note: “BONDING_SLAVE” value is available in the ethernet configuration file as a parameter “_nm_name” and also “mode=1” indicates active-backup policy  ( mode=0 indicates Round-robin policy).

2)     configure both the ethernet interface eth0 and eth1 like below

            # vi /etc/sysconfig/network/ifcfg-eth-id-xx:xx:xx:xx:xx:xx

            BOOTPROTO='none'

            STARTMODE='off'

            USERCONTROL='no'

                                        

3)     Restart the network service

            # service network restart

4)     To check the status of the bond0 interface use the below command

            # cat /proc/net/bonding/bond0
