LABEL DESCRIPTION
Name This is read-only if you are editing an existing trunk. When adding a new trunk, enter a
descriptive name for this trunk. You may use 1-31 alphanumeric characters, underscores
( ), or dashes (-), but the first character cannot be a number. This value is case-sensitive.
_
Load Balancing Select a load balancing method to use from the drop-down list box.
Algorithm
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).
Load Balancing This field is available if you selected to use the Least Load First or Spillover method.
Index(es)
Select Outbound, Inbound, or Outbound + Inbound to set the traffic to which the Zyxel
Device applies the load balancing method. Outbound means the traffic traveling from an
internal interface (ex. LAN) to an external interface (ex. WAN). Inbound means the
opposite.
The table lists the trunk's member interfaces. You can add, edit, remove, or move entries for
user configured trunks.
Add Click this to add a member interface to the trunk. Select an interface and click Add to add
a new member interface after the selected member interface.
Edit Select an entry and click Edit to modify the entry's settings.
Remove To remove a member interface, select it and click Remove. The Zyxel Device confirms you
want to remove it before doing so.
Move To move an interface to a different number in the list, click the Move icon. In the field that
appears, specify the number to which you want to move the interface.
# 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.
