Hi,
We have several SONOS speakers on the same network with our corp systems. As more and more AV equipment is being added to the network, we stared moving AV equipment in to a separate VLAN, SONOS devices have not been moved yet.
Looking at the traffic generated by SONOS we are seeing SSDP packets sent as Mutlicast and Broadcast. If we move SONOS in to an AV vlan, SSDP will get blocked by the router. While we can allow Multicast traffic to bypass the router using IGMP, don't think it's an option for broadcast. The data in both broadcast and multicast messages is identical, so hopefully clients will be able to locate SONOS devices once they are moved in to an AV VLAN and we are forwarding only multicast messages from AV VLAN to data VLAN.
Questions:
Should we see SSDP traffic generated by the clients looking for SONOS ? Do we need to allow multicast in both directions? From AV VLAN to DATA VLAN and from DATA VLAN to AV?
Thasnks
