How to trigger stop capture based on frame count in STC

Is there any option to trigger the stop capture action in STC based on the packet count. Say I want to make STC learn that when my packet count reaches 100 (on a port) capture should be stopped. How can I do it . Please suggest GUI option and the API too. I referred CaptureFilterStopEvent but could not get top on it :(

I am attaching a sample config with this logic.

capture stop.rar

Note :

1. Traffic should be sent at a very low rate, I am using 1FPS rate

2. Clear all counters before starting sequencer

I can't see any stop events in Capture, based on frame count. We might have to trigger 'stop capture' using command sequencer after verifying a result counter like port RX frame count.

Thanks Sukesh. But this is a capture buffer analysis- from buffer we can play around the frame numbers, it does not stops the capture. We would like to stop the capture based on the counts..

Can we do a polling on frames count while capturing packets in STC ports ? - this may be a solution to overcome the trigger action.
