nputool
The nputool allows for configuring and testing the switch ASICs.
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.
