Chapter 5 WAN & 3G Cellular Screens

LAN-Cell 2 User’s Guide

Since WAN has a smaller load balancing index (meaning that it is less utilized than Cellular),

the LAN-Cell will send the next new session traffic through WAN.

To configure Least Load First, select Least Load First in the Load Balancing Algorithm

field.

LABEL DESCRIPTION

Active/Active

Mode

Select Active/Active Mode and set the related fields to enable load balancing on

the LAN-Cell.

Load Balancing

Algorithm

Set the load balancing method to Least Load First.

Time Frame You can set the LAN-Cell to get the measured bandwidth using the average

bandwidth in the specified time interval.

Enter the time interval between 10 and 600 seconds.

Load Balancing

Index(es)

Specify the direction of the traffic utilization you want the LAN-Cell to use in

calculating the load balancing index.

Select Outbound Only, Inbound Only or Outbound + Inbound.

Interface This field displays the name of the WAN interface (WAN and Cellular).
