mep mep-id: Specifies a MEP by its ID in the range of 1 to 8191.

negative negative-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Negative. The negative-time argument represents the delay time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds.
Usage guidelines
After a track entry is created, you can only use the track cfd delay command to modify its notification delay settings. To modify other settings, you must delete the entry and create a new one.
