It doesn't work in either situation. Although, I'm not aware of APs blocking traffic like that unless client isolation is enabled. Which, in this case, it is not.

It's a configuration test software from Laerdal medical. We're in the process of making changes to the way their devices communicate, so we're running the configuration verification tool and it's failing on the network pieces. We have their configuration guide for normal Cisco controllers, which walks through adding custom mdns strings and modifying settings, but there's nothing for Meraki.

It's just 2 windows laptops connected to wireless, each running the vendor's software. The software works perfectly when the two laptops are wired, but the multicast goes missing when both laptops are wireless. We didn't expect this to be the case, since both wired and wireless devices are all configured to use the same vlan 10.

I'm not sure if the multicast to unicast conversion is doing it. Our network is around ~1,100 APs and we're only testing on 1-2 APs, so turning off that setting seems like a mighty big hammer for such a small nail. I've checked but am not seeing any firewalls in the way. I've made sure they're turned off for this. Client isolation is not enabled.

I think I might be misunderstanding something about how Meraki handles multicast. We have 4 scenarios, but only 3 work. 1. broken - two laptops in a client/server pair. the client says "_simlink._tcp.local" queries looking for its server, the server is constantly broadcasting its address. When the two are wired on vlan 10, it works perfectly. When the two are connected wirelessly through an MR42 to vlan 10, the traffic can't make it through, according to Wireshark. It looks like some apple bonjour traffic from other devices on vlan 10 is making it through, but not the traffic we're looking for 2. working - apple devices using the bonjour gateway. easy peasy, just not relevant above since we're not sending traffic to a different network. 3. working - video encoders and decoders using the IGMP querier settings in meraki, all within same vlan 4. working - video encoders and decoders using the PIM sparse mode through a nexus switch, to traverse vlans. We're trying to figure out how to get the first scenario working, where we don't need to traverse vlan, it's not apple's bonjour, and as far as I'm aware, we don't need IGMP. Thanks in advance.

I have the same experience as @BlakeRichardson. I'm on the IT vlan and I have cameras on a variety of other vlans. I didn't have to set up anything special to get direct stream working. My vlan has access to those client vlans.

MV10 the security camera, or MT10 the temp sensor? Either way, if this were me I'd start by connecting a laptop to that vlan, in that location, on that AP, and make sure traffic is passing. I've been burned by a missing VLAN tag too many times.

I think that depends on the materials of the walls and the density requirements within classrooms. I also try to keep them "as far away as practical" as a rule, but in our classrooms, we haven't often found that to be very possible at a great distance. We have plenty of high-density classrooms and lecture halls with 2,3,4 APs all within 10-20 feet of each other. Most other classrooms are 1 AP per room, probably about 10-15 apart with walls in between. We've had it this way for about 3 years now and performance has been pretty solid. Our profiles keep them at 20 MHz channels, channels 149 and 153 are disabled to prevent interference with Airplay devices. In areas with drywall walls, we turn down transmit strength on 2.4ghz, but many of our buildings are much older and don't require that due to the contruction materials. But, if it was new construction and I had the choice of placement, I'd expect omnidirectional APs to be placed in the center of each room. Having them hug the walls doesn't make sense to me.

I love that we're all doing this, and that Meraki is hosting this and encouraging us to participate, but did anyone else see the news today about Google's Deepmind AI making a massive breakthrough in AI-driven protein folding? While we all fold@home using tens of thousands of GPUs and CPUs, I wonder if we'll no longer be needed soon! Sad day for this competition, but great day for global humanity! If I read the articles correctly, I believe their Alphafold is able to predict with above 90% accuracy in just two weeks already, using just 100-200 GPUs. https://www.cnbc.com/2020/11/30/deepmind-solves-protein-folding-grand-challenge-with-alphafold-ai.html

@JanVincent, I have no idea if I'll win this one since most of my folding apparatus is currently dismantled, but if I can get it back together and come in first again, and you come in second, I'll ask @MeredithW to send the bag to you instead.

Thanks all! This was a lot of fun to participate in, I had never even heard of folding@home before this Meraki contest. With how overwhelming and uncertain everything about COVID has been, it's great that Meraki made many of us aware of this way to contribute.

@Network-dad Fun question. The Macs I deployed through JAMF. Took about 48 hours to get a working deployment that will drop the correct config in place. For some reason that kept breaking the ability to launch on its own. The final version will check the config and if it’s wrong, reinstall and unload/reload the daemon. Bummer that macos can’t fold using the gpu. windows machines I did by hand over RDP. I had the installer and accessory files in a network share to make it quicker, and used a .bat file to update firewall rules and move the config into place. To use the GPU I couldn’t install it as a service, so if those reboot I can tell in my central FAHcontrol and can log back in. I have 1 Linux VM running using the fling appliance. I gave it the whole host, which is normally great at being a vm host, but is surprisingly terrible at folding.

@Network-dad no supercomputer here lol, just a lot of empty classrooms during covid shutdowns and an interest in trying to help somehow.

@JanVincentah yes, sorry I didn't mention that. My FAHcontrol is configured to monitor about ~130 machines, with machines ranging anywhere from the 20,000 per day to the 750,000 per day.

@JanVincent I check it in both places. ExtremeOverclocking is good at tracking the 24hour average, but I'm not sure it's entirely accurate. In the FAHControl application, it says I'm at 9,173,000 for today. I think ExtremeOverclocking actually took about 72 hours for the 24 hour average to catch up and "match" the estimate from FAHcontrol. edit: I mean I do think EO is accurate, I'm just not sure it updates as quickly as I expected to large changes in daily point totals.

@Network-dadI wish I could push it a little more, but I've actually had to slow down a bit. For a few days there I was at ~13,000,000 a day, but I ran into some cooling issues so I bumped a bunch down to "low", so I'm currently around ~9,500,000 a day

@Network-dad woah nice! I'm jealous... most of my devices are macs, which don't support GPU folding. I haven't tried OCing any of my windows cards, I figure everything is already hot enough as is. Your laptop alone pushes you up into the top tier of team contributors. It's fun watching the extemeoverclocking page to see our projected growth in team rankings. We've moved from 590 down to 380 in the last few weeks, and EO has us moving up another few positions every day, although the competition is certainly getting fiercer now. https://folding.extremeoverclocking.com/team_summary.php?t=243108

@Network-dadnice, that's great! What kind of cards are you using? I have 6x GTX 1070s which each push about 750,000 points a day. But I also have 16x old Quadro K2000 cards that only push about 20,000 points a day. I wonder how some of the newer cards perform... even the 1070 is a few years old now.
