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
Algorithm

Select a load balancing method to use from the drop-down list box.

Select

Weighted Round Robin

to balance the traffic load between

interfaces based on their respective weights. Weighted round robin is
activated only when the first group member interface has more traffic
than it can handle.

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. 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

Double-click an entry or select it and click

Edit

to open a screen where

you can modify the entry’s settings.

Remove

To remove a member interface, select it and click

Remove

. The ZyWALL

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.

Member

Click this icon to open a screen where you can select an interface to be a
group member.

Mode

Select

Active

to have the ZyWALL always attempt to use this connection.

Select

Passive

to have the ZyWALL only use this connection when all of

the connections set to active are down. You can only set one of a group’s
interfaces 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. This ratio determines how much
traffic the ZyWALL sends through each member interface. The higher an
interface’s weight is (relative to the weights of the interfaces), the more
traffic the ZyWALL sends through that interface.

Ingress
Bandwidth

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.
