DESCRIPTION
Name
This field displays the name of the selected system 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.
