Chapter 14 Trunks

ZyWALL USG 1000 User’s Guide

Each field is described in the table below. 

Table 80   Configuration > Network > Interface > Trunk > Add (or Edit)

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. 

If you select an interface that is part of another Ethernet interface, the 
ZyWALL does not send traffic through the interface as part of the trunk. 
For example, if you have physical port 5 in the ge2 representative 
interface, you must select interface ge2 in order to send traffic through 
port 5 as part of the trunk. If you select interface ge5 as a member here, 
the ZyWALL will not send traffic through port 5 as part of the trunk.

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.
