IEEE 802.3ad The Ethernet interfaces are aggregated in a group and
each slave shares the same speed. This mode provides
load balancing and fault tolerance. Make sure the
switch supports IEEE 802.3ad standard and the correct
LACP mode is configured.
Balance-tlb (Adaptive
Transmit Load Balancing) 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 load balancing and fault
tolerance.
Balance-alb (Adaptive
Load Balancing) Include 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 receive load balancing is achieved by
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
address for the server. This mode provides load
balancing and fault tolerance.
