Balance XOR
Balance XOR balances traffic by splitting up
outgoing packets between the Ethernet
interfaces, using the same one for each specific
destination when possible. It transmits based on
the selected transmit hash policy. The default
policy is a simple slave count operating on Layer
2 where the source MAC address is coupled with
destination MAC address. Alternate transmit
policies may be selected via the
xmit_hash_policy option. Balance XOR mode
provides load balancing and fault tolerance.
Supports static
trunking. Make sure
static trunking is
enabled on the
switch.
Broadcast
Broadcast sends traffic on both network
interfaces. This mode provides fault tolerance.
Supports static
trunking. Make sure
static trunking is
enabled on the
switch.
IEEE 802.3ad
(Dynamic Link
Aggregation)
Dynamic Link Aggregation uses a complex
algorithm to aggregate adapters by speed and
duplex settings. It utilizes all slaves in the
active aggregator according to the 802.3ad
specification. Dynamic Link Aggregation mode
provides load balancing and fault tolerance but
requires a switch that supports IEEE 802.3ad
with LACP mode properly configured.

Balance-tlb
(Adaptive
Transmit Load
Balancing)
Balance-tlb uses channel bonding that does not
require any special switch. The outgoing traffic
is distributed according to the current load on
each Ethernet interface (computed relative to
the speed). Incoming traffic is received by the
current Ethernet interface. If the receiving
Ethernet interface fails, the other slave takes
over the MAC address of the failed receiving
slave. Balance-tlb mode provides load balancing
and fault tolerance.
