The nputool tests the NPU in the system. The nputool verifies that ports are up and traffic between the ports is working either using the CPU-generated packet or using IXIA connected to port-1 and port-2 based on the configuration. Tests Tests are shown in the following sections. CLI options The nputool shows the available options with the nputool -h or nputool command.
