9.12.2 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.

Ingress Bandwidth This is reserved for future use.
This field displays with the least load first load balancing algorithm. It displays the
maximum number of kilobits of data the USG is to allow to come in through the
interface per second.
Note: You can configure the bandwidth of an interface in the corresponding interface edit
screen.
Egress Bandwidth This field displays with the least load first or spillover load balancing algorithm. It
displays the maximum number of kilobits of data the USG is to send out through the
interface per second.
Note: You can configure the bandwidth of an interface in the corresponding interface edit
screen.
Spillover This field displays with the spillover load balancing algorithm. Specify the maximum
bandwidth of traffic in kilobits per second (1~1048576) to send out through the
interface before using another interface. When this spillover bandwidth limit is
exceeded, the USG sends new session traffic through the next interface. The traffic of
existing sessions still goes through the interface on which they started.
The USG uses the group member interfaces in the order that they are listed.
