Is this problem only because of Roon? I was hoping the 2960 was going to be plug and play,I do not use Roon, just the Naim App to access my Core and internet radio.
it’s just plug and play No-Q. But with Roon , it’s a specific problem. Only Roon, but not for everyone.
Simon will explain very probably.

The Cisco Catalyst switch should be plug and play on a healthy home network which I am sure is the vast majority of cases. However it is a commercial device that correctly uses specific protocols. If there is a fault or issue on your home network that was being ignored before because you were using cheap consumer equipment, you can’t assume industrial grade equipment will similarly ignore errors unless you tell it to!.
If you want the Catalyst device to act like a basic consumer device in this case and ignore IGMP, then you need to log in to the switch and disable global IGMP snooping.
Alternatively you leave IGMP snooping on… (recommended) and set an IGMP querier server on the switch…and this means the switch then handles the multicast group advertisement messages to replace any perhaps errant advertisers on the home network.
Hardly plug and play in this case, but you will only need this if your previous switch device was ignoring and papering over network faults…
or simply go back to using a basic consumer switch, which ignores and simply promiscuously broadcasts this data across your home network at the expense of increased processing load for hosts such as your streamer (which may affect SQ of course… but if the case you will have already become used to any possible SQ performance hit)
Roon can operate in ipv6 if available, and that can be more reliable for discovery techniques compared to IPv4 in some cases.
Wow…this could get complicated, thanks for the info Simon. I am not going to stress over it until the switch arrives.Right now I am not using any switch, just the modem supplied by my provider, and my Router.The Core/NDS are wired into the router,I also have a laptop wired into it. I did pick up two Cat5e, and two Cat6 cables to get me started.
Just to be absolutely clear, it isn’t a universal problem with Roon. The problem for me only occurs when I use the Roon Remote app on my iPad to connect to the Roon Core and control my music selection. I have no problem connecting to the Roon Core from my (ethernet connected) Windows 10 PC and the Roon app installed on this PC.

Hi Simon,
I have just logged on as admin to my Sky Q router and have discovered that IPv6 is already enabled on the router, which means that I will need to look elsewhere for a solution to my iPad connection problems. I am a little confused by the fact that when I reinstalled the Roon Remote app on my iPad yesterday, it connected for a period of 15 to 30 minutes before losing the connection completely.
I will try now to log into the switch (it was factory reset so I hope I will be able to do this - do you know what the default admin password is likely to be?) and try disabling global IGMP snooping since I have absolutely no idea of how to "set an IGMP querier server on the switch.
Did you say that disabling IGMP snooping would negate the possible SQ benefits of using a Cisco router? I could put up with this if I can get it to work with my iPad - my main reason for trying out the Cisco was that I need an extra (6th) port on the switch in my AV room and my current TP-Link switch only has 5. Any SQ improvement would have been a bonus.
By the way, I seem to remember you stating in another thread that you have Sky Q. If you do, and assuming that you are using the Sky Q router for your broadband access then your network setup might be similar (albeit probably more sophisticated) to my own. Have you not had any similar issues on Roon Remote access from your iPad?
There won’t be a password. What you will have to do is obtain a USB to Console cable (eBay), this is then connected to the 2960 and your PC, power cycle your 2960 and follow the prompt in the terminal window on your PC. There are guides from Cisco on how to do this if you do a search on Google.
All that’s then needed is to enable the switch as an IGMP Querier (IGMP snooping should be enable by default). Again a Google search will help here. No loss of SQ and everything gets found 
Strange! I have just reinstalled the Cisco switch in my network - this time with only the network cable (plugged into a different port) , Roon Rock NUC and Sonore microRendu connected to the switch, and so far no iPad Remote Roon connectivity problems.
I’ll give it a few hours then connect the rest of my devices and see what happens.

Yes, so the next thing to try is disabling the IGMP snooping on your Wifi access point settings on your Sky router…
It might be that has interoperability issues with the version of IGMP your advertiser on (possibly Roon Core on whatever OS/Platform it’s running on) is using.
Naim had a lot of issues with this in the early days with various home network devices/broadband routers misbehaving and SSDP.(as used by UPnP).
This does suggest to me a Sky router /Wifi access point issue. An alternate if really stuck is use a more general purpose Wifi access point connected to your switch… but try IGMP snooping disabling first on your Sky broadband router.
Thanks, but I am now hopeful I won’t actually have to make any changes at all.
My iPad Roon Remote control point has had no problems whatsoever connecting to my Roon Core today. It has been absolutely rock solid.
Simon,
I’m not sure if it’s a Sky router/Wifi access point issue or not, but I seem to have isolated the problem.
I have discovered by a process of elimination that the problem occurs whenever (and only when) I have my Sky Q TV box connected by ethernet to the Cisco switch. The problem occurs consistently.
Whenever I connect the TV box to the switch, iPad Roon Remote connectivity to the Roon core (attached to the same switch) is lost. Whenever I remove the ethernet connection to the Sky Q TV box the connection returns. This happens whichever port I connect the TV box to, and I am using a cat 6 ethernet cable.
Does this make any sense to you at all? It doesn’t make any logical sense to me. Could it be a faulty cat 6 cable? I’ll try swapping cables when I have some time later on.
A bit of a pain, but at least I appear to have found a consistent contributory factor for the issue.
Just substituted a cat 5 cable that was lying around for the Sky Q TV box connection and although it appeared to work for a little bit, connectivity was lost after about a minute. As soon as I unplug the cat 5 cable Roon Core connectivity from my iPad is restored.
So it doesn’t appear to be an issue with the ethernet cable but it does appear to be an issue that relates in some way to the Sky Q TV box, and the issue occurs both when the box is switched on and when it is in standby mode.
If you have a Sky router and a Sky Q box, are they connected via their own built in ‘Ethernet over mains’ as this might be causing issues? Just a shot in the dark, but in some cases I’ve heard that this is activated without the customer being aware that it even exists.
Thanks Chris,
Are you sure that Sky Q has an inbuilt ‘Ethernet over mains’ capability? I cant see any reference to this when I log into the router as Admin. There are 2 ethernet sockets on the Sky Q box. I run two cat6 ethernet cables from the box - one to the (now Cisco) switch in my AV room and the other to a TP-Link switch (that I may eventually replace with a Cisco switch) in my study which functions as my main music room.
To be honest, I don’t know if all Sky boxes/routers have them. I’ve had a couple of their routers, and haven’t come across it myself, but then I don’t have a Sky Q TV thing. It just occurred to me that if you did have one running, it might cause a conflict if you try to run proper Ethernet or WiFi at the same time, quite apart from any interference it might be spreading all over the place.
Thanks Chris.
Just been told by the Sky support desk that although older Sky boxes used to have inbuilt powerline adapters for connectivity to each other, this is no longer the case. Sky Q boxes use wifi for connectivity and no longer have inbuilt powerline adapters.
A good suggestion though.
Good to hear that they’ve ditched the powerline stuff. Good luck!!
Hi, sorry it no makes sense to me, other than perhaps you have devices on your home network using different versions of IGMP… and the devices will try and use lowest common version, and that might be causing an issue. I connect my Sky Q boxes to my Catalyst switches and I don’t experience your issues, with Roon or anything else… so can’t really comment further without looking at debug.
As far as inbuilt SkyQ powerline adapters I switch mine off (of course) … it’s done in the installer settings/secret menu. Sounds like on the new SkyQ models this is by default?
As far as using two SkyQ switch ports… I wouldn’t… connect your devices back to your Cisco switch for reliability / correctvIGMP snooping etc. Definitely best not to daisy chain for best reliability.
Cheers
Simon
I see a few of you mention connecting Sky boxes to the 2960,I thought the whole purpose of using the 2960 was to ONLY connect your audio gear to it?
Looks as though you have a slightly older version of the SkyQ box. When I go into the installer settings (secret) menu, there is no powerline option choice at all - I have seen screenshots of the powerline option(on or off) in older boxes, but it’s simply not there any more which is obviously a good thing. The other options on the same page are identical to those on the older boxes.
By the way, I don’t actually daisy chain switches. My two switches (located in different rooms) are both connected directly to the SkyQ router.
