9–Linux Configuration for Bonding Mode and Virtual LAN (VLAN) Linux Bonding Mode

The bonding modes are described in Table 9-1.

Table 9-1. Bonding Modes

Mode	Mode Name	Description
Number
0	balance-rr	This mode uses a round-robin policy; it transmits
		packets in sequential order, from the first available
		slave through the last. This mode provides load bal-
		ancing and fault tolerance.

1active-backupIn this mode, one slave interface is active at all times. If one interface fails, another interface takes over the MAC address and becomes the active interface. This mode provides only fault tolerance. This mode does not require special switch support.

2balance-xorIn this mode, transmissions are balanced across the slave interfaces based on ((source MAC) XOR (dest MAC)) modulo slave count. The same slave is selected for each destination MAC. This mode pro- vides load balancing and fault tolerance.

3broadcast This mode transmits everything on all slave inter- faces. This mode provides fault tolerance.

4802.3a This mode provides standard IEEE 802.3ad dynamic link aggregation. It requires 802.3ad sup- port in the switch, and driver support for retrieving the speed and duplex of each slave.

5balance-tlbThis mode provides adaptive transmit load balanc- ing. Incoming traffic is received only on the active slave. Outgoing traffic is distributed according to the current load on each slave. This mode does not require special switch support.

6balance-albThis mode provides adaptive load balancing through ARP negotiation; both transmit load balanc- ing (TLB) and receive load balancing are supported for IPv4. This mode does not require special switch support, but does require the ability to change the MAC address of a device while it is open.
