The Linux bonding driver provides a method for aggregating multiple network interfaces into a single logical “bonded” interface. The behavior of the bonded interfaces depends upon the mode; generally speaking, modes provide either hot standby or load balancing services. Additionally, link integrity monitoring may be performed.
There are only few steps for creating a Bonging on Fedora Â which is explained as below.
Login to your Fedora system and go to Console and go to privileged mode by typing su.
Then go to the following Location
[root@pds7 ~]# cd /etc/sysconfig/network-scripts/ [root@pds7 network-scripts]#
Under Â /etc/sysconfig/network-scripts/ create a file called ifcfg-bond0 ,see the example
vi ifcfg-bond0 then paste the following code, please give your ip in IPADDR filed
ONBOOT=yes DEVICE=bond0 IPADDR=172.16.1.37 NETMASK=255.255.255.0 GATEWAY=172.16.1.1 BOOTPROTO=none TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=no
Then save the file and edit ifcfg-eth0 and paste the following
SLAVE=yes MASTER=bond0 ONBOOT=yes TYPE=Ethernet DEVICE=eth0 BOOTPROTO=none PEERDNS=yes USERCTL=no IPV6INIT=no
Then save this and edit ifcfg-eth1 file and paste the following
SLAVE=yes MASTER=bond0 ONBOOT=yes TYPE=Ethernet DEVICE=eth1 BOOTPROTO=none
After saving this file, just go to /etc folder and edit the modprobe.conf file and paste the following:-
alias bond0 bonding options bonding miimon=100 mode=active-backup primary=eth0
we are almost done . Just restart the network services on the command line
service network restart
To verify the bonding status please use the following command
you will get the following out put
Ethernet Channel Bonding Driver: v3.3.0 (June 10, 2008) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Link Failure Count: 0 Permanent HW addr: 18:a9:05:42:14:c8 Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 18:a9:05:42:14:cc
All the best
