nputool
The nputool allows for conguring and testing the switch ASICs.
The nputool tests the NPU in the system. The nputool veries that ports are up and trac between the ports is working either using
the CPU-generated packet or using IXIA connected to port-1 and port-2 based on the conguration.
Tests
Tests are shown in the following sections.
CLI options
The nputool shows the available options with the nputool -h or nputool command.
