Netgear GS724Tv4 - Data Storms

  • October 17, 2020

My home network uses a Netgear GS724Tv4 managed switch.

My Sonos gear comprises:

  1. Connect: Bedroom, Series ID: C100, WM: 0. OTP: 1.1.1(1-17-5-zp90-2.1)
  2. Play:3: Kitchen, Series ID: A100, WM: 0, OTP: 
  3. Beam: Sitting Room, Series ID: A100, Audio In: , WM: 0
  4. Play:1: Sitting Room (RS), Series ID: A200, WM: 0
  5. Play:1: Sitting Room (LS), Series ID: A101, WM: 0, OTP: 
  6. Sub: Sitting Room, Series ID: A101, WM: 0, OTP: 

This all works beautifully. But in my garden shed (connected via a 50m ethernet cable to the managed switch) I also have 2 Sonos 5’s (wired daisy chain).

I seem to be suffering data storms as the 5’s keep disappearing. 

My key Managed Switch settings are:

  • Spanning Tree State: Enable
  • STP Operation Mode; STP
  • Forward BPDU while STP disable: Enable
  • Bridge Priority: 0
  • Bridge Max Age (secs): 20
  • Bridge Hello Time (secs): 2
  • Bridge Forward Delay (secs): 15
  • Spanning Tree Maximum Hops: 20
  • CST Port Configuration (All ports) : STP Status : Enable, Fast Link: Disable, BPDU Forwarding: Enable, Path Cost :10,  External Port Path Cost: 10

 

Any help HUGELY appreciated please.

What other Sonos units are wired to the switch? 

You talk of “2 Sonos 5’s (wired daisy chain)”. The only 5/Five which has dual ports is the old Play:5/gen1. Is this what you mean?

With multiple devices already wired through the switch I doubt you have a conventional broadcast storm. I assume it’s a plain Ethernet cable straight between the switch and the first P:5. Hopefully you’ve checked that the cable itself isn’t faulty?

Indeed it’s a brand new cable and in fact I actually laid no less than 4 cables and I get the same issue with them all.  The fives work perfectly when In the house.   The way they keep disappearing from the controller app on both phone and Mac is so odd, and that only

occurs when actually playing music.

 

I have also connected a TP-link wire less access point daisy chained off the last Five in the shed which is providing a good WIFI service according to my phone (and of course allows the Sonos phone app to work.

It’s possible that one of the Play:5s is connecting to the house wirelessly and the cable is being ignored.

Go to http://x.x.x.x:1400/support/review, substituting the IP of one of the wired house players, e.g. the Beam.

Click on Network Matrix and locate the rows representing each of the shed Play:5s. They should contain grey cells, except for the left column. If not, we’ll have to do some more digging.

Annoyingly the 2nd Five (called “Gym”) is not always visible.  The other one called “Defect” is showing as grey although on saying that I notice one of  the columns calls itself ‘undefined’?

Looks to me (from my router’s device table) like the Fives are:

“Defect”: 00:0E:58:59:C6:CE 192.168.8.167

“Gym”: B8:E9:37:2F:FE:02 1192.168.8.163

The “undefined” columns are (a) “Gym”, which has gone AWOL, and (b) the 5GHz radio of “Sitting Room”, which is quite normal.

You said the 5s were daisy-chained. Which way around? “Defect” is showing as (a) wired and (b) tertiary, which suggests it’s not connected directly to the switch.

If “Gym” is the one connected to the switch it would suggest it’s malfunctioning at the Sonos application level, but still able to switch an Ethernet signal. In that case try a factory reset.

I was trying to disable wifi on both Fives today.  I was able to do that for GYM but not DEFECT.  They are both eBay purchases so it is quite possible one of them is not perfect. This arvo I switched the order so that the long ethernet cable connects from managed switch to DEFECT, then DEFECT to GYM then GYM to the TP-L WAP.  Right now my Mac SONOS App shows all devices except the one called DEFECT (which is the one which I can't disable WIFI for):
