Analyze and test
The diagnostics tool is used to analyze and test the SmartNICs. The test result includes sensors, SDRAM information, and time synchronization information. A traffic test is also performed. In order to run the test, you need to loop port 0 and port 1, port 2 and port 3 etc. as shown in the figure below.
The diagnostics tool is under the installation directory on Windows e.g. C:\Program Files\Napatech3\bin.
Cabling to run the diagnostics tool
Example
The following example is the output of the diagnostics tool on Linux.
