The seven types of modes available, as mentioned below:

mode=0 (balance-rr): This mode is based on the Round-robin policy and it is the default mode. This mode provides load balancing and fault tolerance kind of FEATURES. It routes the packets in the Round-robin fashion that means from the FIRST available slave through the last.

• mode-1 (active-backup): This mode is based on the Active-backup policy. Only one is active in this band,and another slave will ACT only when others fail. The MAC address of this bond will be available only on the adapter PART to avoid confusing switch. This mode will also provide fault tolerance.
• mode=2 (balance-xor): This mode sets an XOR (an exclusive or) mode that is the source MAC address is XOR’d with destination MAC address which provides load balancing and fault tolerance feature. Each destination MAC address the same slave selected.
• mode=3 (broadcast): This method is based on the broadcast policy that will transmit everything on all the slave interfaces. It provides the fault tolerance feature. This can be used for only specific purposes.
• mode=4 (802.3ad): This mode is called the Dynamic Link Aggregation mode that has it created aggregation groups having the same speed. It requires a switch that supports the IEEE 802.3ad dynamic link. The slave selection for outgoing traffic will be done based on the transmit hashing method. This can be changed from the XOR method via the xmit_hash_policy option.
• mode=5 (balance-tlb): This mode is known as ADAPTIVE transmit load balancing. The outgoing traffic will be distributed based on the current load on each slave and the incoming traffic is received by the current slave. If incoming traffic fails, the failed receiving node is replaced by the MAC address of another slave.
• mode=6 (balance-alb): This mode is known as adaptive load balancing.
