4.3.3. Creating SLAVE Interfaces

The channel bonding interface is the master and the interfaces to be bonded are referred to as the slaves. After the channel bonding interface is created, the network interfaces to be bound together must be configured by adding the MASTER and SLAVE directives to the configuration files of the slaves. The configuration files for each of the slave interfaces can be nearly identical.
Example 4.2. Example Slave Interface Configuration File
For example, if two Ethernet interfaces are being channel bonded, eth0 and eth1, they can both look like the following example:
DEVICE=ethN
NAME=bond0-slave
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
In this example, replace N with the numerical value for the interface. Note that if more than one profile or configuration file exists with ONBOOT=yes for an interface, they may race with each other and a plain TYPE=Ethernet profile may be activated instead of a bond slave.
