Description
Switch Required
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 uses only 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.
