Description
Fault Tolerance (Failover)
Active-Backup
All traffic is sent and received using the interface that was first added to the
trunking group. If this primary interface becomes unavailable, the secondary
interface will become active.
Broadcast
Transmits the same network packets to all the network interface cards.
Load balancing & Failover
Balance-tlb
Incoming traffic is received by the current interface. If the interface fails, a slave
interface takes over the MAC address of the failed interface. Outgoing traffic is
distributed based on the current load for each interface relative to the interface's
maximum speed.
Balance-alb
Similar to Balance-tlb, but offers additional load balancing for incoming IPv4
traffic.
Balance-rr
Transmits network packets sequentially to each network interface card in order to
distribute the internet traffic among all the NICs.
Balance-xor
Transmits network packets using the Hash algorithm, which selects the same NIC
slave for each destination MAC address.
802.3ad dynamic
Uses a complex algorithm to aggregate NICs and configure speed and duplex
settings.
