The total amount of data transferred along with the calculated network bandwidth is displayed. You can alter some of the test features using command-line parameters. Table 6.3 lists the parameters that can be used. If you want to extend the test to 60 seconds showing an update every 5 seconds you use the following command iperf -c 192.168.1.100 -t 60 -i 5 Client connecting to 192.168.1.100 TCP port 5001 TCP window size 16.0 KByte default 3 local 192. 168. 1.6 port 1340 connected with 192.168.1.100 port 5001 ID Interval Transfer Bandwidth 3 0.0- 5.0 sec 55.5 MBytes 93.1 Mbits sec 3 5.0-10.0 sec 55.4 MBytes 92.9 Mbits sec 3 10.0-15.0 sec 55.4 MBytes 93.0 Mbits sec 3 15.0-20.0 sec 53.5 MBytes 89.6 Mbits sec 3 20.0-25.0 sec 53.4 MBytes 89.6 Mbits sec 3 25.0-30.0 sec 54.8 MBytes 91.9 Mbits sec 3 30.0-35.0 sec 54.8 MBytes 91.9 Mbits sec 3 35.0-40.0 sec 55.0 MBytes 92.3 Mbits sec 3 40.0-45.0 sec 55.5 MBytes 93.2 Mbits sec 3 45.0-50.0 sec 55.5 MBytes 93.0 Mbits sec 3 50.0-55.0 sec 55.6 MBytes 93.2 Mbits sec 3 55.0-60.0 sec 55.5 MBytes 93.2 Mbits sec 3 0.0-60.0 sec 660 MBytes 92.2 Mbits sec A report is displayed every 5 seconds of the test. A final report is also displayed showing the results for the overall 60-second test. The -P option can be used to run simultaneous tests between the two test hosts. Each test stream will contain the same data pattern and the same data and time limits as defined on the command-line parameters iperf -c 192.168.1.100 -P 2 Client connecting to 192.168.1.100 TCP port 5001 TCP window size 16.0 KByte default 108 Chapter 6 3 local 192. .168. .1.6 port 1346 connected with 192.168.1.100 port 5001 6 local 192. .168. .1.6 .
