and drag technique and the detailed configuration items can be hidden or shown by clicking on the WAN
interface individual block. As an example, Figure 15 shows the wan interface detailed configurations
and as the first interface in the failover progression with the load balancer in the secondary position.
The Load Balance block appears as if it were a WAN interface block on the Load Balance & Fail Over
page. By default the Load Balance feature is disabled and therefor the default behavior is any interfaces
that are below the Load Balance block are not used. If the Load Balance feature is enabled then all
interfaces that have a viable route to the Internet are used in the load-balancing scheme.
3.2.4.2 Configuring the Load Balance Capability
The load balance capability of the G1 IG has 2 modes of operation: compatibility mode and aggressive
mode. In compatibility mode traffic is split among the available interfaces in a more conservative
manner while in aggressive mode traffic is split up into more pieces and spread among the available
interfaces more equally. Users should see better throughput results with the aggressive mode and it is
recommended as the default balancer mode, however if issues are experienced with a particular
application then switching to compatibility mode may alleviate the issue.
Not all traffic is compatible with load balancing technology. If your application consistently fails to
operate with the load balancer enabled please contact G1 for further assistance.
3.2.4.3 Load Balance & Fail Over Advanced Configuration
Each interface block on the Load Balance & Fail Over page has a set of configuration items that allow the
user to fine-tune how interfaces are shared and monitored. The configuration items of the connectivity
or viability test can be seen below.
Figure 14: Load Balance & Fail Over Interface Viability Configuration Items
The Load Balance Distribution value can range from 1-10 and is the amount of shares or weight that the
interface has in relation to all interfaces when using load balancing. If all interfaces have the same
capacity then they should all have the same Distribution value. If one interface has twice the capacity
then it should have a Distribution value that is twice the value of the other interface. The Load Balance
Distribution value is only used in load balancing configurations.
