mode { yes | no | persistent}
Required. Specifies whether tracing is disabled, enabled and persistent, or enabled and nonpersistent. See "Remarks" for additional information.
If the mode parameter is set to yes, nonpersistent tracing is active until the mode is either set to no or the computer is restarted.
If the mode parameter is set to no, tracing is stopped for either persistent or nonpersistent tracing.
If the mode parameter is set to persistent, tracing will still be active even after the computer is restarted.
The default value for mode parameter is nonpersistent.
