Balance-rr
(Round-Robin
)
Round-Robin mode is good for general purpose
load balancing between two Ethernet interfaces.
This mode transmits packets in sequential order
from the first available slave through the last.
Balance-rr provides load balancing and fault
tolerance.
Supports static
trunking. Make
sure static trunking
is enabled on the
switch.
Active Backup
Active Backup only uses one Ethernet interface. It
switches to the second Ethernet interface if the
first Ethernet interface does not work properly.
Only one interface in the bond is active. The
bond's MAC address is only visible externally on
one port (network adapter) to avoid confusing the
switch. Active Backup mode provides fault
tolerance.
General switches
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.
