The traffic summary shows how WAN optimization is reducing the amount of traffic on the WAN for each WAN optimization protocol by showing the traffic reduction rate as a percentage of the total traffic. The traffic summary also shows the amount of WAN and LAN traffic. If WAN optimization is being effective the amount of WAN traffic should be lower than the amount of LAN traffic.

You can use the refresh icon to update the traffic summary display at any time. You can also set the amount of time for which the traffic summary shows data. The time period can vary from the last 10 minutes to the last month.
