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.
