I wanted to post a few clarifications regarding SONOS and Spanning Tree Protocol that have been raised in this thread.
SONOS ZonePlayers use 802.1D Spanning Tree (STP) for loop prevention between wired ZonePlayers and the wireless SonosNet Mesh Network. The Spanning Tree running on ZonePlayers is compliant with IEEE 802.1D and can inter-operate with other IEEE 802.1D and IEEE 802.1w compliant devices. Note: IEEE 802.1w is an updated version of the Spanning Tree protocol called Rapid Spanning Tree. The two types of STP protocols are compatible and 802.1w should revert to inter-operate with 802.1D devices (such as Sonos). Therefore, 802.1w Ethernet switches will work with Sonos ZonePlayers.
SONOS ZonePlayers CAN be connected to Ethernet switches that do NOT support Spanning Tree as long as the Ethernet switches do not interfere with the STP BPDU packets transmitted between ZonePlayers. This is typically never the case and these switches pass the BPDU packets like any other packet.
If the Ethernet switches that Sonos ZonePlayers are wired to DOES support Spanning Tree, the Spanning Tree on those switches must be configured properly. Ethernet switches that support Spanning Tree typically have their STP settings disabled. This also typically means that these switches will block/discard the BPDUs coming from the ZonePlayers. When the ZonePlayers are not able to see BPDUs, they cannot detect there is a shared transmission medium between the Zones and this will typically result in loops in the network. The solution to allow the use of these switches with Sonos is to enable and configure the Spanning Tree on the Ethernet switches. The configuration settings on each switch are different and the appropriate documentation for those products should be consulted. Note: Some switches have a setting that is called Pass BPDUs or equivalent. This setting when present allows the BPDUs between the ZonePlayers to pass freely through the switch without actually enabling STP on the the switch. Typically, setting this function also works, but again please review the switches product documentation.
A good guideline for Ethernet switches is if the switch says it supports Spanning Tree, either 802.1D or 802.1w, then its configuration settings and user documentation should be examined before wiring multiple ZonePlayers to the switch. If the switch does not state it supports Spanning Tree, 802.1D, or 802.1w, it will probably work fine with Sonos.
SONOS ZonePlayers do NOT require a connection to the same Ethernet switch. Different ZonePlayers can be connected to different Ethernet switches which are in turn connected to each other. The only requirement is that Sonos ZonePlayers must be able to actively participate in 802.1D Spanning Tree and not have BPDU transmission blocked between them. There is no Sonos limitation that prevents wiring multiple ZonePlayers to multiple Ethernet switches.
IEEE 802.1D has a recommended bridge span limitation of 7 bridges. This means that the total number of connected bridges from one end of the network to the other should not exceed 7 bridges. This typically only comes into play when daisy chaining Sonos ZonePlayers together by wiring one ZonePlayer to the next. In this case, the guidelines is when daisy chaining ZonePlayers, do not exceed 7 ZonePlayers wired together. If wiring multiple ZonePlayer to a single Ethernet switch, typically the number of spans will only be 3 or 4 (I.e. much less than 7). Except in the daisy-chain configuration, this limit of 7 bridges/7 ZonePlayers, is rarely ever hit.
A number of comments have used the term router and switch interchangeably in regards to this topic. Sonos ZonePlayers in the same HouseHold MUST be connected to the same routed network. A Spanning Tree cannot span two or more routed networks. In addition all Sonos ZonePlayers and Controllers must be on the same routed IP network in order to properly communicate and function. Typically, two or more routed networks are not seen in the household environment except by accident (Example. A carrier provides a new router in a network that already had a router and the original router was not removed).
Hopefully this information has clarified a number of items and not added additional confusion.

Hi,
for everyone running a network with multiple STP-capable core switches, e. g. HP Procurve, it might be interesting to know, that Sonos has not implemented path costs of links according to the current standard 802.1t, but still uses 802.1D.
Current switches use path costs of 200,000 for an 100B-T interfaces, whereas Sonos still uses 10 (for a full-duplex 100B-T)
http://en.wikipedia.org/wiki/Spanning_tree_protocol#Data_rate_and_STP_path_cost
Everyone affected will have Sonos zone players use a Sonos wireless cascade to the elected root switch, even if the core switches have a Gigabit-Link (at current 802.1t path costs of 20,000)! This leads to a cascaded load over possibly weak wireless links.
Workaround:
Manually configure trunk connections between core switches at path cost 10. If done so, the Sonos zoneplayers will use the nearest wired connection!
Wish list:
Sonos is encouraged to use the current standard 802.1t for path cost to avoid problems with switch trunks in current standard configurations.

Found this in another thread:
I called Sons support today. I had purchased a new ZoneBridge to help coverage in my house.
I set the ZoneBridge as the wired main hub. As I added th ZP back one by one, all was great except for one ZP80. The network kept setting the ZP80 as the rootbridge, which negated the new Bridge.
The procedure Sonos walked me through:
1. HTTP to the rootbridge you want to remove and root. http://#.#.#.#:1400/advconfig.htm
2. Set the "FirstZP:" field to disabled
Click SUBMIT
3 Now HTTP to the Zone Player you want to be Root. http://#.#.#.#:1400/advconfig.htm
4. 2. Set the "FirstZP:" field to enabled
Click SUBMIT
5. Also be sure to reboot both of the units after they have been been properly configured using the power cable, or by attaching /reboot to the ZP url.
If you ever see more than one 'Root Bridge' in the network matrix, be sure to turn one of the zones root bridge setting off. Also be sure to reboot both of the units after they have been been properly configured using the power cable, or by attaching /reboot to the zp url.
I did it in about 2 minutes and it worked perfectly. Now all my Tunnels are Green

+1 for the workaround. Linksys (Cisco) SLM2008 switches also appear to use 802.1t for path costs. Manually setting 802.1d path costs results in the network using wired links in preference to wireless. Also had to lower the bridge priority (to 0) on one of the switches to ensure that my Zone Players weren't being elected root bridge.
Wish list:
Sonos is encouraged to use the current standard 802.1t for path cost to avoid problems with switch trunks in current standard configurations.
+1 for the wish list although I'd propose that Sonos make this configurable.
Rougu,
Please don't take this the wrong way, I am still waiting for clarification, but this statement I feel does not provide the full requirements:
By trunk connections, do you mean between cascaded switches and/or link aggregation?
On the Cisco switches I am configuring the port that connects to the next switch is not configurable, it defaults to a path cost of 0.
I think the post is lacking the statement that each port on the switch that is wired to a Sonos ZP also needs a path cost of 150 or less to avoid the SonosNet connecting to a near by ZP as well as the wired connection. Is this correct? If so, please include in your post, would be helpful for the novices :)
Thanks.

Hi,
I'm trying to confirm if my wired network could be compatible with this STP issue.
I'm wondering about installing this switch (Linksys EG008W). But according to its specifications there is no metion about the specific protocol you mentioned.
Its datasheet says:
Key Features
8 RJ-45 10/100/1000Mbps auto-sensing half/full duplex switched ports
All ports suppport auto MDI/MDI-X cable detection
Fully compliant with IEEE 802.3, 802.3u, 802.3x, 802.3ab
Non head-of-line blocking architecture
Full-duplex IEEE 802.3x flow control and half-duplex backpressure with intelligent port-based congestion detection and broadcast rate control
This IEEE compliant is compatible with sonos STP requirements?
Thanks

It should be fine. It's an unmanaged switch which should simply flood STP traffic transparently.
I have not experienced any issues with the EG008W.
I never touch the STP on my switch in the living room. Maybe a litltle tweak in the RSTP could help.

I've actually taken some notes on the GS108T (although my notes are for the -200)
While it shouldn't necessarily require the RSTP step, it does seem to require the IGMP Snooping set to enabled.

Hi there,
We have had a lot of problems on many of our client sites recently.
The key to fixing these has been to set all of our managed switches with a low bridge priority.
set them to:
- switch one: 4096
- switch two: 8192
- switch three: 12288
- etc. incrementing in multiples of 4096
This will ensure that the Sonos is not the root bridge.
Mr Sonos,
Could you please set your default bridge priority to something really high?
Because Sonos MAC addresses start with 00:0E they are pretty much always the lowest MAC and will win the BRIDGE PRIORITY BATTLE by default which will lead to issues in the network because the switches will do what the Sonos tells them.
Also do we need to have IGMP snooping running for best Sonos performance? will this help to contain the multicast traffic to sonos only devices?
Is there some online training that your dealers can do that will teach us about the advanced aspects of Sonos network best practice?
Thanks.
Gerard.

FYI the bridge priority is set at 0x9000 (36864) for all Sonos players/bridges except for the first unit to be registered, which has a priority of 0x8000 (32768).
Also do we need to have IGMP snooping running for best Sonos performance? will this help to contain the multicast traffic to sonos only devices?
I seem to recall that people had problems when IGMP snooping was enabled, as SSDP traffic wasn't being forwarded correctly.

Hello,
Thank you for the explanations regarding STP.
I have well understood that SONOS ZonePlayers can be connected to Ethernet switches that do not support Spanning Tree as long as the Ethernet switches do not interfere with the STP BPDU packets transmitted between ZonePlayers.
Does this guarantee that connections will be done using the wired network?
In other words:
I have a very simple Ethernet network with a unique central switch to which RJ45 wall plugs are directly connected. My goal is to connect the Sonos ZP to the RJ45 wall plugs and be sure that the network used will be the wired one and not the Sonos Wireless Network.
Does this imply to use a manageable switch to be able to set a higher STP priority for/to the wired links?
Or with a simple switch (that does not support STP but do not interfere with the STP BPDU) the Sonos ZPs will deactivate all the wireless links?
Thank you for your help,
Regards,
Ced

A dumb switch would not add to the path cost, which means that the Sonos units will prefer the wired link over the wireless. Usually problem arises with managed switch that uses RSTP path costs, which would be higher than the wireless links. In those cases, you must manually reconfigure the managed switch to use classic STP or manually set the path costs for the Sonos ports to decent values.

I have now tried to battle with STP and Sonos. My network switches are all netgear gs108t v1 + v2 and gs716t. I have two sonos components a zp90(connect) and a play:1. Theese are connected to different switches. On the play:1 the port on the switch goes into discarding state, port cost is set to 10.
Does anyone know if flow control should be enabled for the ports Sonos components are wired into?
Linksys by default sets all ports to 'none' for flow control instead of auto.
Just curious if this would help my situation. I have occasional hiccups with the STP settings where my system becomes unresponsive, but I'm trying to isolate STP issues that could possibly be causing my Linksys LAPAC1750PRO WAP's to stop working.

The Linksys EG008W that was mentioned earlier has been discontinued, any suggestion on a currently available alternative?
After many years of troubles and endless hours of trying to reconfigure my switches and numerous fine updates on the SONOS software providing good features to us customers, I still wonder why SONOS never provided a feature allowing to switch from the very old IEEE 802.1D-1990 standard (the one proposing the cost to be 19 for 100MB link) to the more recent version of 1998 which would be more in line of nowadays default settings off the shelf switches are using.
Is there a reason why?

My guess is that this is just a legacy, but requires big changes to work as expected. The players calculates a dynamic path cost depending on the wireless signal quality, and to "adjust" this according to 802.1W standards is probably not as straight forward as one would expect.
Changing this would also break all current installations, as well as breaking backward compatibility with 802.1d-only switches (although, I would guess that these are rare today). Best option would be to make this configurable, but that is another complexity added to a system that strives for simplicity. There's probably a reason that most modern switches has a "classic" mode available too, maybe because there is still a big need for it.
Another reason could be that the linux kernel only seem to support 802.1d, and 802.1w seems to be available as a separate daemon. This might not integrate well with how the Sonos player operates, or add to much memory footprint to be usable in these limited devices, who knows.
Now, I only use 1 switch, and didn't have an issue reconfiguring it to work well with Sonos. It simplifies it a bit if you can isolate all your Sonos gear to 1 switch, but you should be able to correctly configure multiple switches as well, as long as you can lower the path cost for uplinks as well.
While it shouldn't necessarily require the RSTP step, it does seem to require the IGMP Snooping set to enabled.

Well, had my network go down today with a storm. Was working fine but I noticed that the Playbar network cable was unplugged. Plugged it in and down it went (I have another unit plugged in).
Now I had three gs108tv2's in a chain, all with stp enabled, however this did not seem to work. Set them up as shown above and now it's working perfectly again ! Cheers.
Sorry for resurrecting an old thread, but these ancient path costs used by Sonos has resulted in me having to disable WiFi on the new CONNECT I just added to my system (like I've had to do on other Sonos units). Without doing so, the Sonos desperately wants to use the crappy wireless link (minimum 60% duty cycle on all 2.4Ghz channels due to urban density) to the nearest neighbor instead of the wired Ethernet available to it. And since my topology is root switch distribution switch Sonos, it's not a simple matter to fudge the port cost on the distribution switch, since the cost of the link from root to distribution still dwarfs the cost Sonos applies to the wireless interference. (Sonos is showing 802.1W costs received from its wired neighbor (which does RSPT) and not even trying to scale that down to 802.1D much less the ancient 802.1D values it is using.)
Basically, I have one wired Sonos device with WiFi enabled to feed the one wireless PLAY:3 unit I have and then the rest of the wired devices I've had to disable WiFi because of the broken STP costs. The current STP costs are used by pretty much all switches at this point, and have been for years. Sonos really needs to get with the times on this one. And it won't cause backwards compatibility issues, since the modern costs are higher than the ancient STP costs Sonos uses. And since Sonos requires all devices to be on the same firmware level, they'd calculate equally as they do today, even if you had a really old wired switch topology in between them using the lower costs.

Hello I really need your Help because you seem the best on SONOS products in the world.
If you could read the poor french forums and all the people crying for what I know now to be a broadcast storm !
I am so happy to finaly be able to put a name on my problem.
Anyway now I need you help to solve it because I don't have a managable switch with STP. Is there a quick and easy solution on the config menus of the players ?
Do i have to disable WIFI to all my RJ45 wired SONOS players ? Would it help or my only solution is to buy new switches with stp manageable ?
Excuse my english and thx for you help

Charlie, what is the model of network switch that you have? There are some unmanaged switches that block STP, though they are not common.
Deactivating the wireless on your wired Sonos players might also work, but leave it enabled on only one of them, so any wireless players can still connect.
----------
French Translation from Google... Hopefully it's accurate. :)
Charlie, ce qui est le modèle de commutateur de réseau que vous avez? Il y a des commutateurs non administrables qui bloquent STP, si elles ne sont pas communs.
Désactiver le sans fil sur vos lecteurs Sonos câblé pourrait également fonctionner, mais le laisser activé sur un seul d'entre eux, de sorte que tous les joueurs sans fil peuvent toujours se connecter.
