Sonos Multicast Problems on ZoneDirector
Problem Description:
When using Sonos speakers they rely heavily on multicast to initiate a connection and stream music to the speakers however if more than 5 pings are missing then the Sonos device will stop playing music.
How to fix:
On each access point run the following commands:
Commands | Explanation |
set qos eth0 directed multicast disabled | This prevents the AP from converting multicast traffic to unicast |
set qos eth0 igmp disable |
|
set qos eth0 classification disable |
|
On the controller in the WLAN Configuration:
Commands | Explanation |
no qos directed-multicast | This prevents the WLAN from converting multicast traffic to unicast |
qos directed-threshold 0 | This disables BOTH directed broadcast and directed multicast on the SSID. If there is only a single client it will receive broadcast traffic as broadcast and multicast traffic as multicast. |
The following tick boxes are additional items which need to be set.
