DESCRIPTION

Member

Click this table cell and 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

Click this table cell and 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 assigns to each member

 

interface. The higher an interface’s weight is (relative to the weights of the interfaces),

 

the more sessions that interface should handle.

 

 

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.

 

Note: You can configure the bandwidth of an interface in the corresponding interface edit

 

screen.

 

 

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.

 

Note: You can configure the bandwidth of an interface in the corresponding interface edit

 

screen.

 

 

Spillover

This field displays with the spillover load balancing algorithm. Specify the maximum

 

bandwidth of traffic in kilobits per second (1~1048576) to send out through the

 

interface before using another interface. When this spillover bandwidth limit is

 

exceeded, the ZyWALL sends new session traffic through the next interface. The traffic

 

of existing sessions still goes through the interface on which they started.

 

The ZyWALL uses the group member interfaces in the order that they are listed.

Click OK to save your changes back to the ZyWALL.

8.2.2 Configuring the System Default Trunk

In the Configuration > Network > Interface > Trunk screen and the System Default section, select the default trunk entry and click Edit to open the following screen. Use this screen to change the load balancing algorithm and view the bandwidth allocations for each member interface.

Note: The available bandwidth is allocated to each member interface equally and is not allowed to be changed for the default trunk.
