User's Manual

Transmit based on [(source MAC address XOR'd with destination MAC address)

modulo slave count]. This selects the same slave for each destination MAC

address. This mode provides load balancing and fault tolerance. This mode

provides fault tolerance and load balancing.

• broadcast

Transmits everything on all slave interfaces.

This mode provides fault tolerance.

• 802.3ad

IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share

the same speed and duplex settings. Utilizes all slaves in the active aggregator

according to the 802.3ad specification. Require: a switch that supports IEEE

802.3ad Dynamic link aggregation.

• balance-tlb

Channel bonding that does not require any special switch support. The outgoing

traffic is distributed according to the current load (computed relative to the

speed) on each slave. Incoming traffic is received by the current slave. If the

receiving slave fails, another slave takes over the MAC address of the failed

receiving slave. This mode provides fault tolerance and load balancing.

• balance-alb

Adaptive load balancing: includes balance-tlb plus receive load balancing (rlb)

for IPV4 traffic, and does not require any special switch support. The receive load

balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP

Replies sent by the local system on their way out and overwrites the source

hardware address with the unique hardware address of one of the slaves in the

bond such that different peers use different hardware addresses for the server.

mii

Specifies the MII link monitoring frequency in milliseconds. This determines how

often the link state of each slave is inspected for link failures. A value of zero

disables MII link monitoring. A value of 100 is a good starting point. The

use_carrier option, below, affects how the link state is determined. See the High

Availability section for additional information. The default value is 0.

primary

A string (eth0, eth2, etc) specifying which slave is the primary device. The

specified device will always be the active slave while it is available. Only when the

primary is off-line will alternate devices be used. This is useful when one slave is

preferred over another, e.g., when one slave has higher throughput than another.

The primary option is only valid for active-backup mode.
