    It is set like that for the default stack.

      The only switches we have on campus now are Meraki or dumb switches. Most things are on Meraki’s. The vendor turned “port flooding” off. I’m going to check but I believe I’ll still have the issue. I do not think that’s it. I’ll post back as soon as I know.

        To update this issue… I had a network engineer look at this issue. He determined that we had our multicast setting set to flood all ports. So far disabling this has fixed the majority of our multicasting issues.

        One thing we did notice is that we had one old switch going to one of our labs that seems to fail on multicast and not unicast. Multicast works everywhere else with that image. We will be replacing that switch at some point but I believe that switch is the culprit. It’s an older 10/100 “dumb” HP switch (commercial grade).

        So far I have not experienced any other issues with that version of FOG.

        Thanks again for all the help!

          @joe-gill Well in a way I’m glad this issue was a FOG specific one, but rather an infrastructure. I can say multicasting is a bit of a fickle beast no matter what imaging technology you are using. When it works, its great.

          It sounds like your network was configured for dense mode multicasting where it would just send the mutlicast stream to all ports even if there were no multicast subscribers.

          Thank you for providing solid feedback and sticking with this issue until it is resolved.

          Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!
