netkvm-wmi.cmd is a simple developer-oriented tool that allows access to NetKVM driver to query or control the behavior of the driver.

It is based on WMI interface of the network driver: WMI commands are converted to custom OID that the OS sends to the NetKVM driver.

In case of multiple NetKVM devices (multiple network adapters) each command of the netkvm-wmi.cmd is executed for all the devices.

The batch file requires administrative permissions, run it from administrator command line.

Examples of most useful commands are:

  • query initial configuration

netkvm-wmi.cmd cfg

  • query all run-time statistics:

netkvm-wmi.cmd stat

  • query run-time RSS statistics

netkvm-wmi.cmd rss

  • query run-time TX statistics

netkvm-wmi.cmd tx

  • query run-time RX statistics

netkvm-wmi.cmd rx

  • reset only TX | RX | RSS statistics

netkvm-wmi.cmd reset tx

netkvm-wmi.cmd reset rx

netkvm-wmi.cmd reset rss

  • reset all the statistics

netkvm-wmi.cmd reset

  • set logging level of the driver to 3 at runtime:

netkvm-wmi.cmd debug 3

For the list of available commands run netkvm-wmi.cmd without parameters.

To add new commands for development/testing purposes see the implementation of existing WMI commands:
