Interop Test

Purpose:

In this test scenario, the LANforge CT523c generates packets on the Ethernet port toward the wired side of the Access Point (AP). The AP then transmits these frames to the real devices connected via Wi-Fi. LANforge performs an interoperability test by cycling through each set of stations sequentially. In this configuration, throughput is measured on only one device at a time, which is ideal for obtaining peak performance data. The system automatically progresses through the devices, running throughput tests for the specified duration for each client. Chambers and attenuators are not required for this test; however, running it inside isolation chambers typically provides more stable and reliable results. This feature is supported in LANforge version 5.4.9 and later.

Test Case:

Step 1:

Open Chrome and enter the LANforge Manager's IP address followed by port 5454 in the address bar. This will open the WebGUI Login Page as shown below:

Step 2:

Select Interop and enter login credentials to sign in:

• Username: test@lanforge.com
• Password: lanforge

Step 3:

After logging into the WebGUI, the user should enter the LANforge Manager's IP address and select Connect. The Device Manager page will then be displayed, showing all real devices connected to the Candela Box. This view includes devices across multiple operating systems, such as Android, iOS, Windows, Linux, and MacOS.

• NOTE: Real Devices must be clustered using Interop Cookbooks and have a unique hostname to appear in Device Manager.

Step 4:

After reviewing the connected devices, the user should navigate to the Testing page. In the Testing page, select the required devices from the Available Devices panel, choose Interoperability Test from the Tests panel, enter necessary test parameters, and then click Run Test to begin the interoperability test.

Interoberability Test Parameters

1. Instance Name^* - Specifies the custom name for the test. The instance name must begin with an alphabet. Special characters and numbers cannot be used at the beginning of the instance name. Each test must have a unique instance name.
   • Example: Interoperability_Test
2. Duration^* - Defines the total time for which the Interoperability test will run, in minutes.
   • Example: 5
3. Client Resource^# - Automatically populated with the Resource IDs of the selected devices.
   • Example: 101
4. Upstream Port^* - Indicates the AP's wired connection to the LANforge Ethernet interface used to generate and run traffic.
   • Example: eth2-192.168.50.41
5. Traffic Type^* - Specifies the type of traffic to be used in the test.
   • Example: TCP/UDP
6. Traffic Direction^* - Defines the direction of traffic to used in the test.
   • Example: Download/Upload/Bi-Directional
7. Rate^* - Represents the total requested download or upload rate. Measured in Mbps.
   • Example: 100
8. Configuration^** - Allows to set the SSID, password, and Wi-Fi encryption so that the client disconnects and reconnect to the network before performing the test.

^* - Mandatory
^** - Optional
^# - Automatically filled

Step 5:

After clicking Run Test, an instance will be created using the specified test name. During the test execution, the user can monitor the real-time graph, review logs in the Log Viewer, and observe the configured test parameters. Once the test has completed, the user should generate the PDF report from the Testing page and save it to the desired directory.

Note: When the test is initiated, the L3 endpoints are created in LANforge Manager. After the Test completes, a detailed PDF report, along with CSV data captured at each timestamp, is saved in the webgui_reports folder located under the home/lanforge directory on the LANforge Manager.
