VPLS destroying

Hello peoples,
i have wireless connection which work with VPLS.
So during the working this tunnel sometimes unregistered and then registered, and i have loose some packets.
In VPLS section of mikrotik i see the TX errors… So how i can debug the VPLS, to understand what is te problem with tunnel…

Look for underlaying problems with the connectivity. Monitor your ip connections, and routing. Increase your log level (/system logging) to f.ex debug and your should get more sensible information in your log files.
