For it to work you will need to set up your switch correctly. You can extrapolate the details from Page 36 of the Teranex Mini IP Video Manual.
I have E2E enabled on my switch, but all connected IP Video 12G units are registering as the master clock. When I plug in a new unit, it shows PTP 'listening' for a short while, then sets itself to master. This tells me that they are not receiving any PTP messages from the other units.
This appears to be causing a problem with the video signal dropping out on destination units every minute or so as it resynchronises (though this could be a misdiagnosis/incorrect assumption on my part).
So two questions, would non-functioning PTP result in these kind of behaviour (brief drops of signal)?
and can you give me any information on how PTP is implemented by the units in the absence of a separate grandmaster clock? The details on page 35 of the manual are specifically for configuring a standalone grandmaster clock, are there any specific switch configurations that I need to be aware of?
Many thanks
