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

DEVICE=bond0
NAME=bond0
TYPE=Bond
BONDING_MASTER=yes
IPADDR=192.168.43.100
PREFIX=24
ONBOOT=yes
BOOTPROTO=none
BONDING_OPTS="mode=1 miimon=100"

Note the directive BONDING_OPTS line, bonding uses a variety of options and mode. Modes can be:

• mode 0 or balance-rr: Sets a round-robin policy for fault tolerance and load balancing.
• mode 1 or active-backup: Sets an active-backup policy for fault tolerance.
• mode 2 or balance-xor: Sets an XOR (exclusive-or) mode for fault tolerance and load balancing.
• mode 3 or broadcast: Sets a broadcast policy for fault tolerance. All transmissions are sent on all slave interfaces.
• mode 4 or 802.3ad: Sets an IEEE 802.3ad dynamic link aggregation policy. Creates aggregation groups that share the same speed and duplex settings.
• mode 5 or balance-tlb: Sets a Transmit Load Balancing (TLB) policy for fault tolerance and load balancing. The outgoing traffic is distributed according to the current load on each slave interface. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed slave. This mode is only suitable for local addresses known to the kernel bonding module and therefore cannot be used behind a bridge with virtual machines.
• mode 6 or balance-alb: Sets an Adaptive Load Balancing (ALB) policy for fault tolerance and load balancing. Includes transmit and receive load balancing for IPv4 traffic.
