I was wondering how to make suer that the AP does not drop multicast traffic when it is on standalone mdeo. On a Zone Director, each WLAN can be set individually by unticking the box for "Drop multicast traffic on this WLAN" - but how can you be sure on a standalone AP?
I found this: wlan9 up AP wlan9 1 94:f6:65:78:53:2c chromecast2
set qos wlan9 directed multicast disable set qos wlan9 igmp disable
set qos eth0 directed multicast disable set qos eth0 igmp disable
but I am not sure it does the exact same thing - I am trying to use a Chromecast and it needs MDNS to work and I believe this is the issue.
Yes you are issuing commands telling the AP not to snoop IGMP and reply on behalf of clients, which means let MDNS/Multicast flow thru Eth/Wireless interfaces, and let the clients answer the IGMP join/update messages directly. Has this worked for you?
