Can you send a snippet of code that causes the problem? The POX and/or switch logs? Etc.? (The last item of the POX FAQ has a bunch of suggestions.)
Also... how long does this loop run for? In general, you don't want to have any event handler run for very long. If it's taking many seconds, other switches may decide the connection is dead. -- Murphy On Jul 5, 2014, at 10:42 PM, farshad tajedin <farshad.taje...@gmail.com> wrote: > hi > i have a problem with switches in my topology, when i message to switches in > a for loop i see some of switches disconnect and then connect again i dont > know why?!!! > please help me > > -- > Best Regards > > Farshad Tajedin
