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.
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.
