Hi,

To create bonding, Follow below steps.

1. create a file ifcfg-bondX and add below lines.

DEVICE=bond0
IPADDR=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
USERCTL=no
BONDING_OPTS=”bonding parameters separated by spaces” # Such as BONDING_OPTS=”miimon=100 mode=1″
NM_CONTROLLED=no

2. After creating bonding interface, its time to configure slave interface.

3. Edit interface files and add below lines.

DEVICE=ethX
BOOTPROTO=none
ONBOOT=yes
HOTPLUG=no
MASTER=bond0
SLAVE=yes
USERCTL=no
NM_CONTROLLED=no

4. Restart the network service to load the newly added configuration.
#service network restart

This is explained a bit further at below link.

@Muthu,

Open each file and modify the MAC address, that’s it and don’t forget to restart the network service.
