10.14.2 Configuring the System Default Trunk
In the Configuration > Network > Interface > Trunk screen and the System Default section, select the
default trunk entry and click Edit to open the following screen. Use this screen to change the load
balancing algorithm and view the bandwidth allocations for each member interface.
Note: The available bandwidth is allocated to each member interface equally and is not
allowed to be changed for the default trunk.

Load Balancing
Algorithm
Select the load balancing method to use for the trunk.
Select Weighted Round Robin to balance the traffic load between interfaces based on
their respective weights. An interface with a larger weight gets more chances to transmit
traffic than an interface with a smaller weight. For example, if the weight ratio of wan1
and wan2 interfaces is 2:1, the Zyxel Device chooses wan1 for 2 sessions’ traffic and wan2
for 1 session’s traffic in each round of 3 new sessions.
Select Least Load First to send new session traffic through the least utilized trunk member.
Select Spillover to send network traffic through the first interface in the group member list
until there is enough traffic that the second interface needs to be used (and so on).
The table lists the trunk’s member interfaces. This table is read-only.
# This column displays the priorities of the group’s interfaces. The order of the interfaces in
the list is important since they are used in the order they are listed.
Member This column displays the name of the member interfaces.
