    2323 === Passive Graphs Lite ===
    24     This provides you a basic view of the graphs that is set in a  view only mode and provides no control over pausing the live view or zoom in/zoom out . To view traffic with this view, click on the "Passive Graphs Lite" Button from modules list in the top lefthand corner of the page. This will create a graph selection window (see below) on your screen. By default, the CPU, ICMP, and IP graphs are selected. Adjust the selection to the graphs you want to see. Select the node or nodes in the topology for which you would like to see graphs. Then click the "add graphs" button. If you have selected multiple nodes, you may prefer to click on "add graphs with titles," as this will clearly identify the node from which the graph is taken. Like the ssh box, you can iconify or deiconify the graph selection box by clicking on the task bar.

    3131== Generating traffic with iperf ==
    3232
    33 The iperf program can be used to generate traffic. Iperf needs to be run on both the source and destination node. Iperf should first be started at the destination in server mode using the command "iperf -s." To run iperf on the source, type "iperf -t 30 -b 1000M -c destination" where destination is the IP address (or name) of the node where the iperf server is running.  This will tell iperf to generate traffic for sixty seconds, sending at a rate of one hundred megabits per second. The names of the hosts in your topology can be found in the /etc/hosts.

To run iperf on the source, type '''iperf -t 30 -b 1000M -c destination''' where destination is the IP address (or name) of the node where the iperf server is running.  This will tell iperf to generate traffic for thirty seconds, sending at a rate of one thousand megabits per second. The names of the hosts in your topology can be found in the /etc/hosts.
