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 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).

 

 

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

 

 

ZyWALL 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 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.
