Broadcast Traffic Issue

Mon Feb 17, 2020 12:40 am

I have a CRS328 running swos 2.10.
It's in an AV environment with trunk ports connected to WiFi AP's and then a bunch of LAN ports on a single VLAN.

We have Apple TV's connected to each projector and are also using AirTame, Audinate Dante and NDI.

About once per day (sometimes it lasts two), the clients stop seeing the apple TV's and Airtame devices and Dante stops working (which are broadcasting their presence).
A reboot of the switch resolves the issue and suddenly they can all see the Apple TV's and Airtames again and everything is fine for a while before the issue comes back.

I have replaced our old 2960 switches with the Microtik and we didn't used to have this problem.
I've tried changing every setting in SWOS that makes sense.

Flood Unknown Multicast is turned on.
Limit Unknown Unicast is turned off.

Update: Turned off IGMP and everything flooded. So have turned it back on.

IGMP Snooping is turned on
Learning is turned on

Most of these protocols are MDNS based, has anyone seen any issues with broadcast traffic in swos?
