LABEL 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 ZyWALL 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.
Mode This field displays Active if the ZyWALL always attempt to use this connection.
This field displays Passive if the ZyWALL only use this connection when all of the
connections set to active are down. Only one of a group’s interfaces can be set to
passive mode.
Weight This field displays with the weighted round robin load balancing algorithm. Specify the
weight (1~10) for the interface. The weights of the different member interfaces form
a ratio. s
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 ZyWALL is to allow to come in through the
interface per second.
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 ZyWALL is to send out through
the interface per second.
