Sonos S1 on Zyxel managed switches: Anyone running a wired or hybrid (wired+wifi) Sonos S1 system

Options

I have real issues getting my Sonos S1 speakers (multiple Play:5 1st Gen) running on my Zyxel managed switches (XMG1930-30HP and XS1930-10HP; both with L3 license and most current 4.80 firmware).

I have multiple VLANs present (but no inter-vlan communication) and IGMP Snooping is activated. Besides that DHCP Server Guard is on, BPDU Flow Control is on, but not much else.

When I try to find the Speakers and add them to the app, they are never found. Also not after factory reset of the Sonos speakers.

Anyone has a successful setup on Zyxel smart/managed switches running with Sonos S1?

(Also the support doc from Zyxel did not help me unfortunately; I also tried the Sonos doc about STP configuration, but also did not work.)

    Hi @StefanNetworker,

    We have some users who successfully set up Zyxel smart/managed switches running with Sonos devices.

    To better help you solve the problem, could you provide a simple topology and the configuration of your switches?

    Hi Melen,

    Topology is not complicated:

    2 Switches (XMG1930-30HP, XS1930-10HP) connected over fiber on the SFP+ ports (port 29). Additionally there is a MikroTik Cloud Core Router 2004-1G-12S+2XS connected over DAC on the 2nd SFP+ port (port 30) on the XMG1930.

    No wired loops.

    On 3 ports (Port 2,4,6 of the XMG1930) there are 3 Zyxel NWA210AX wifi access points connected which are powered by the switch over PoE and use VLANs as well for the different WIFI SSIDs. All that works fine.

    Essentially there are multiple isolated VLANs which realize different isolated networks. No connection between these VLANs. You can see them as completely isolated. They are only accessible over the router for some special cases. Broadcast and multicast domains are only inside the VLANs.

    The VLANs span over both switches and also the access points and the MikroTik router as well. That all works well.

    On the XMG1930 config below you can also see, that some ports are attached to VLAN 1 (which is my mgmt VLAN where also some equipment for controlling the whole house is in) and VLAN 10 exclusively. That is intentionally.

    I have 6 Sonos players in the house: 4x Sonos Play:5, 1x Sonos Port, 1x Sonos Play:1. All running on Sonos current S1 firmware, no way to update, the oldest devices are first gen Sonos Play:5 from 2009, but worked before relocating very well.

    Currently the Port, Play:1 and one of the Play:5 is working fine. All wired, WIFI disabled completely, as they anyway could not see each other because of concrete walls with a lot of steel inside.

    I bought Smart switches mainly because of their VLAN capabilities, the port speed, PoE and the amount of ports. So of all features the device has, I mainly intentionally activated the VLAN setup. Some other things like IGMP Snooping, DHCP Guard, DHCP Snooping (which is disabled), rate limiting was only as backup measure as I had serios problems when I connected the Sonoses and faced heavy broadcast storms (Sonos created that as they bridged their SonosNet and connected two wired Sonos players on L2 over SonosNet; this is eliminated). This is gone and under control now. Also all the errdisable counters are zero.

    For making everything work with Sonos I tried to activate IGMP Snooping, which seems to work fine from what I see in the status messages and also in the pcap traces (collected on my laptop with port mirroring and checked in Wireshark).

    I tried to activate MSTP to ensure the spanning tree is controlled by the switch, but I did not succeed with that. See my parallel post.

    See here my configuration (export also attached):

    Hi @StefanNetworker,

    Reply to the problem “When I try to find the Speakers and add them to the app, they are never found.”

    After checking the configuration, it does not have much problem except the MSTP. Please check the parallel post to set it up.
    Moreover, is the device that uses the Sonos APP in the same VLAN as your Sonos devices? If yes, this is more likely the problem with Sonos APP. You might need to find Sonos support for help.

    P.S. Sonos APP uses SSDP (broadcast and mulitcast(239.255.255.250)) to scan the Sonos devices.

    I have Sonos S1 with both wired and wireless Sonos devices (9 total) set up with Zyxel switches (Combination of XGS3700, GS2210, GS1910, and GS1900).

    I have found the way to get them to work is to have all of the Sonos devices and any controller (mobile device or desktop computer) on the same vlan. Set up the non-wired Sonos devices to use SonosNet. Then set up STP, not MSTP or RSTP on the ports the wired Sonos devices are connected to. Be sure your switch is set up as the root bridge.

    Yes, for me also everything is on same VLAN 10. All players and the app. I wanted to avoid multicast routing or cross-VLAN communication exactly to not make it unnecessarily complicated. Also that works well for the working players.

    I can now also confirm, that STP works with MSTP with the working players. I see on the Sonos Web interfacehttp://192.168.20.65:1400/support/review (output of: /usr/sbin/brctl showstp br0 ) that the switch running MSTP is taken properly as the root bridge, all ports where players are connected are up and forwarding. That looks good.

    But unfortunately even after having STP right as far as I can tell, the non connecting players still are not found. Damn it.

    I also already have thread open on Sonos forum, but nothing helpful so far from there. Challenging.

    Many thanks for all the help!
