I turned on Enable Multicast Drop for one of our SSIDs. It seems to be working, however, I noticed that IPv6 discovery and IGMP query packets still flowing through. The default is to leave those packets as exclusions, but I unchecked the boxes so that those items would not be excluded. However, when I look back at the SSID settings, those boxes are still checked. If I un-check them, then save and close, when I go back, they're checked again. I cannot get the un-check to save. I tried a couple different web browsers. Any ideas as to why these exclusions aren't staying disabled? I also tried disabling one exclusion at a time, and disabling other exclusions. The only thing that stays is the default, which is all exclusions are checked except MDNS. The MDNS box is the only thing that actually saves when I check or uncheck it.
