only for situations in which utilizing multiple ports at once is undesirable.

The advanced features of PhobosLink include the ability to choose the
algorithm used for balancing the network traffic load across the different
ports in a group or trunk. These options are only available when
trunking is enabled. They allow one to select between three different
algorithms for choosing the port on which to transmit an outgoing
packet. (The port on which incoming packets are received is determined
by the switch or host on the other side of the connection.)
Currently three transmit policies are available: Adaptive, Fixed,
and Round-Robin.
• Adaptive Mode: - (the default) Dynamically assigns packets going to
a particular destination Ethernet address to the least heavily loaded port.
• Fixed Mode - Uses a static assignment scheme based on the desti-
nation address, and is equivalent to the transmit policy used by most
trunking switches.
• Round-robin Mode - Causes packets to be transmitted alternately
over all the ports in the group regardless of destination address.
N O T E :
Round-robin mode does NOT preserve packet ordering on streams
of packets between pairs of hosts and therefore should only be used
with protocols such as TCP/IP that don’t require packet order to be
maintained. We recommend using the Adaptive or Fixed policy for
typical situations in which a server is connected through a switch to
a network containing many clients, and using the Round-Robin
policy when two server-class machines must be connected together
directly with a high-bandwidth dedicated
