Hi Sandeep, Thanks for these good questions!
A more current version of this configuration would look like this. in0::InfiniteSource -> Queue -> EtherEncap(0x0800, 11:22:33:44:55:66, 66:55:44:33:22:11) -> Counter(COUNT_CALL 100 stop) -> Print -> tr :: TimeRange -> Discard; DriverManager(wait, print >- tr.interval, stop) However, I've checked in some changes to the Git version so that "save tr.interval" will work again. As for why 121 packets were sent, instead of 100: For performance reasons, a "stop" instruction does not immediately stop the router. Rather, it enqueues a stop request, which stops the router soon afterwards. If you wanted to immediately stop the InfiniteSource, you could do this instead: in0::InfiniteSource -> Queue -> EtherEncap(0x0800, 11:22:33:44:55:66, 66:55:44:33:22:11) -> Counter(COUNT_CALL 100 finish.run) -> Print -> tr :: TimeRange -> Discard; finish :: Script(TYPE PASSIVE, print >- tr.interval, write in0.active false, stop) Note how the "finish" script explicitly turns off the InfiniteSource and THEN stops the router. Little Scripts that do multiple things are a quite useful technique for your toolbox. However, over the weekend I figured out a way to speed up "stop" requests in many cases. So if you update the Click sources from git, the *original* configuration will process 100 packets exactly as well.
