iPerf is a standardized network performance tool used to measure UDP or TCP throughput and loss. The iPerf app runs an iPerf3 performance test to a NetAlly Test Accessory or an iPerf server endpoint. To run an iPerf test, you must configure your unit to communicate with your iPerf endpoint. You can manually enter an iPerf server address, or select a NetAlly Test Accessory's address in the iPerf settings.

 

 

 

 

Before you begin, please note there are some limitations:  General: iPerf & Speedtest Limitations

 

You can start an iPerf test from the Details screen for a Test Accessory in the Discovery app using the floating action button.

1. Open the Discovery app, and select an active Test Accessory from the main iPerf Test App Discovery list to open its Details screen.

 

 

 

2.  Tap the floating action button (FAB) "wrench" to open the action menu.

 

 

3.   Select the iPerf app button to open the iPerf app with the IP address populated from the Test Accessory in Discovery.

NOTE: You can also select Browse in the FAB menu to open the Test Accessory's Web Interface, where you can view its status and configure its settings.

 

 

 

To configure the iPerf test settings manually, open the settings on the iPerf screen. Tap each field to enter or revise selections as needed. Changed settings are automatically applied. When you finish configuring, tap the back button to return to the iPerf test screen.

 

1.  IPv4 Address: Tap the field to enter or select the IPv4 address of the target iPerf server. Only IPv4 addresses are allowed for iPerf testing.

 

 

2.  A drop-down list in the IPv4 Address dialog shows all the Test Accessories the unit has discovered through the discovery process, as iPerf Test App well as any Test Accessories that are claimed to the same Link-Live organization as your unit.

 

3.  Port: The default iPerf3 port number is 5201. Tap the field to enter a different port number. 

NOTE: The iPerf port number entered here must match the port number used by your iPerf server.

 

4. Duration: This setting is the length of time for one direction, Upstream or Downstream, of the iPerf test. If the Direction setting below is set to both Upstream/Downstream, the total test time is twice the value set here. Tap the field to select a new duration or enter a custom value. The
default is 10 seconds.

 

5.  Protocol: TCP is the default protocol. Tap the UDP selector to switch to UDP. 

NOTE: iPerf tests running the TCP protocol automatically run at the fastest rate possible. When running a UDP protocol test, the iPerf app attempts to run at the selected Bandwidth.

 

6.  Direction: You can run an iPerf test Upstream, Downstream, or both. The default is Upstream and Downstream. Tap this field to set the test for only one direction.  Upstream and Downstream Bandwidth: These fields only appear if the UDP Protocol is selected. They specify the desired target
bandwidth for the iPerf Test using the UDP protocol.

 

7.  Upstream and Downstream Thresholds: Thresholds are the values the unit uses to grade the test as Pass or Fail. iPerf thresholds are throughput rates. The default is 10 Mbps. Tap the threshold fields to select a different value or enter a custom one.

 

 

 

1. Ensure that you have an active link on the Interface (Test Port) from which you are running the iPerf test. You can do this by running an AutoTest.

 

2. Tap the START button on the main iPerf screen to begin testing.

 

3.  Test characteristics and status are displayed at the top of the iPerf results screen while the lower part of the screen displays a real-time graph of the TCP or UDP Upload and/or Download speeds.
