NIC Bonding On Debian Lenny

[ Thanks to An Anonymous Reader for this link. ]

"The Linux kernel bonding module supports a number of bonding types.
mode=1 (active-backup)
One slave interface is active at any time. If one interface fails, another interface takes over the MAC address and becomes the active interface. Provides fault tolerance only. Doesn't require special switch support
mode=2 (balance-xor)
Tranmissions are balanced across the slave interfaces based on ((source MAC) XOR (dest MAC)) modula slave count. The same slave is selected for each destination MAC. Provides load balancing and fault tolerance.
mode=3 (broadcast)
Transmits everything on all slave interfaces. Provides fault tolerance.
mode=4 (802.3ad)
This is classic IEEE 802.3ad Dynamic link aggregation. This requires 802.3ad support in the switch and driver support for retrieving the speed and duplex of each slave"
