We are experienced issues with AES67 Panels dropping out briefly, the panels would appear to be resetting, but resume its previous state (any keys set to talk would come back still set to talk) after around 4 seconds. 

The panels were fine until part way through the show day. The issue did not appear to be limited to specific panels.  

The matrix also showed an issue on EHX software, but no error was apparent in the monitor screen detail or from the front of the matrix

Solution:

The answers to this issue was a loop back in the network and here is how I found out.

I managed to dedicate the issues causing the panels dropping out briefly.

After lots of looking about, I finally found the 44:a5:6e:a2:9c:f1 Mac Address. I thought this was the Netgear switch but the last letter was different to all of my ports. Continued looking about and said MAC address was my STP MAC, thus quickly finding the error.

Seems that I managed to set the network switch and IPA AES67 to the same IP address (192.168.40.2). Therefore the network switch changed its IP and MAC address internally to cope with the problem. Then every now and again had a blip and dropped a panel.

If only the switch didn’t do this and I would’ve found out it was a problem in setup… whoops.

I’ve left it soaking over the weekend, and I haven’t seen anything in the logs relating to PTP dropping a panel.
