Ubiquiti edge switch and streamer

Hi i plan to move my net to ubiquiti edge routers and switch. I understood that the preferred choiche for streamer is a cisco catalyst in a separate vlan with the upnp server. Do you think that same config with ubiquity can achieve same results?

@simon-in-suffolk i read with interests your posts. Please advise me

Yes, but it’ll need a Unifi rather than Cisco config script.

Just in case you run into an issue with the Edge router on my USG Pro 4 I needed to exclude my Naim streamers from IPS.

Switch I use a Cisco.

Absolutely the same results can be effectively achieved with a Ubiquiti switch. You don’t need to do anything specific… it’s plug and play.

However on the USG I would not use inspection based Intrusion Prevention… the signatures are not comprehensive enough and you will find things may stop working.

The early USG revisions there was no device exempt list under IPS caused a few issues, later Ubiquiti resolved this.

I was thinking about ethernet noise isolation which i don t know if it is at the same level of a catalyst

Sorry Tiberio what scripts do u mean?

Honestly you will be fine… sure they might ‘sound’ slightly different but that is more about tweaking.

I have a combination of Uniti and Cisco. Uniti USG , the 8 port POE 60w switch are the main data hub and this feeds to two othe Cisco 2960’s and two waps . Works well. I turned of IPS reduced bandwidth too much.

If you are going to create a music VLAN (as in your original post) then you’ll need to set it up. You’ll also need some form of routing if you want devices on your music VLAN to be able to communicate with devices on other networks.

There may be a menu driven interface that enables you to do this, but on Cisco and some other swathes (Juniper and HP), I’m used to scripting this. I thought the same applied to Ubiquiti switches,

I have never bothered with a music VLAN. I use an unmanaged HP switch, which I think is as good as it gets for connecting up my streamer. The Ubiquiti should work just as well.

I wouldn’t bother with a music VLAN, as with UPnP one would need to join the VLAN to a dedicated WLAN for the Naim app… all in all one wouldn’t be gaining much… unless you had a really large flat subnet that you wanted to split up.
You can experiment with creating an Ethernet vlan for your streamer to cut down broadcast and ARP processing noise but you will need to set up SSDP helpers on the router otherwise it will fail.
You are best to focus on the correct implementation of IGMP and contrary to Naim’s current company approach, in my opinion then separate your streamer transport from your DAC.

Please Simon give me some details:
1 in the eth vlan only the streamer or the upnp as well?
2 ssdp helpers enabled for other devices like smart tv outside the vlan?
3 explain better work with imp

Thanks a lot

There really is no point in over complicating this stuff.

It can be either… for it to have any real effect it’s only for the streamer, but you will need to programme the router to correctly route UPnP and SSDP. UPnP is not really designed to be routed.
The SSDP helpers are required as SSDP uses a multicast IP address and you need to programme the router to route the SSDP multicast group addresses between subnets. With out this the Naim app won’t discover your streamer or UPnP server.
IGMP is internet group management protocol… when IGMP snooping is enabled amongst other things it monitors and controls which switch ports and WLANs belong to which multicast groups, so unnecessary and load and processing is avoided to devices on your network.
As Garyi says, no real point in doing this unless second nature to you, as you really need to understand how routing and switching works in some detail and you need manageable devices.

Thanks. To résume:
Dedicated 1 host vlan only for the streamer and ssdp services active for upnp services browsing.
Igmp snooping active to avoid multicast eth noise

I agree with @garyi and @Simon-in-Suffolk, you can configure routers and switches to create a music only VLAN, but you need to program the router and switch to do it.

If your goal is to learn more about networking then this may be an interesting project, but if your goal is optimal sound quality then I wouldn’t bother. Streamers play music from buffers and on a home LAN these buffers are always well fed (unless something strange is happening). These buffers and other streamer design considerations remove the need for specialist network configuration.

Using good quality cables, such as inexpensive fully qualified Blue Jeans Cables Cat 5e or 6, will have more effect. Even then it won’t be dramatic like changing DACs, amplification or speakers. I think these type of changes to networks are only heard when you forget the music and listen analytically to the hifi.

If you really want to do this, then you need to enable IP Multicast Routing on your router, and I recommend setting Protocol Independent Multicast Dense mode by enabling IP PIM Dense mode on the routable multicast group interfaces/virtual interfaces on the router, ie connecting your streamer subnet to the UPnP subnet.
Remember to create the iP Unicast static routes on the router to allow unicast IP packets to route between the subnets, and don’t forget you will need a static next hop route on the router interface between the internet and streamer subnet if the streamer subnet is reached by passing through the UPnP subnet.
If you do achieve this you will have provided true Ethernet filtering for the streamer… whether you hear a SQ benefit may depend on how large and busy your home network is.

Ciao Simon i would like to do that but i plan to move to an ubiquity security gw and some switches and i don t know if they support this configuration

Yes I have no idea if the Ubiquiti security gateway supports multicast routing protocol and PIM. You will need to ask Ubiquiti… and then if it does you will need to create and load a bespoke .json file… if you want to do this you are probably better off having a small separate router say from Cisco to create the streamer subnet and route between it and your main subnet where your Upnp and WiFi reside.
