<group title="Bonding Configuration">
<p>A port that has more than one interface is a ``bonded port.'' Bonding
- allows for load balancing and fail-over. Open vSwitch supports
- ``source load balancing'' (SLB) and "active backup" bonding. SLB
- bonding assigns flows to slaves based on source MAC address and output
- VLAN, with periodic rebalancing as traffic patterns change. Active
- backup bonding assigns all flows to one slave, failing over to a backup
- slave when the active slave is disabled. Neither form of bonding
- require 802.3ad or other special support from the upstream switch to
- which the slave devices are connected.</p>
