Dear Community,

a few words to us...

We are not a B&O dealer nor are we extensive B&O users. We are a specialized on high secure LAN/WLAN. 

For our current issue the customers B&O partner has no answer. Allow me to scratched the scenario.

- To avoid high amount of multicast traffic and to secure the networks we have segregated  the network into following VLAN:

- xx.xx.100.xx Management Netwoork

- xx.xx.105.xx VoIP

- xx.xx.107.xx KNX

- xx.xx.108.xx .MultiMedia

- xx.xx.109.xx General network traffic including WLAN APs

- xx.xx.110.xx Gateway network

Inter VLAN routing is enabled, the network switch acts as ta gateway for each VLAN. 

Out network client operates in total 12 B&O network drives speaker system, 4 B&O absolutely high TV sets. All controlled by the B&O App.

The B&O dealer insists that the App is unable to handle the devices if it is out site the Multimedia VLAN.

It must be in the same subnet as the devices. It does make sense when in a small environment but not in a network as scratched. The dealer suggested that the customers changes WLAN SSID when he wants to control multimedia. A situation which is definitely inacceptable. Is there any path we might go to solve the issue? I almost cannot believe that there is no way to manage B&O devices via routed IP traffic.  

The dealer has delivered a multiroom system.

Any idea is more the welcome.

KInd regards

Uwe

I can not answer your question, but maybe you can find some inspiration/some hints in this document:

Thanks a lot for your reply and documentation recommendation! I'll work myself through the document.

Cheers

Hi Millemissan,

I read through the document. As a workaround BeoLink might be an option. Instead of the native B&O App a KNX App could perhaps replace the native app. At least the user would be able to control his devices out site of the media vlan. Only disadvantage is the extra effort involved. I'll call the dealer tomorrow and listen to what he has to say. Though I would prefer a smart network solution by B&O.

Cheers

Uwe

Can you not do a dhcp reservation for the MAC address assigned to the app device?

And put that on the multimedia vlan?

That wouldn't help to solve the issue. The client has a multiroom setup which we have designed to run in its own VLAN but the App doesn't reach the devices because MAC addresses are layer 2 and routing takes place on layer 3. Do you see our dilemma? The WLAN SSID is for all purposes, traffic is controlled by services and routed accordingly. I have the feeling that currently there is no solution unless the system architecture is changed to support such a setup. All network devices in the same subnet might work on small home network but not in a professional network environment. On the other hand our B&O product knowledge is to little and there4 we count on the B&O dealer but in this case he is overstrained. 

Cheers

With Draytek router it could be done.

having tagged and untagged traffic (B&O) sharing across some ports.

https://www.draytek.co.uk/support/guides/kb-vigor-8021qvlan?highlight=WyJ2bGFuIiwiJ3ZsYW4nIiwiJ3ZsYW4iXQ==

 

I would set up your VLANS as per this section,

 

VLAN with a mix of 802.1Q tagged VLANs and untagged VLANs

 

but the only compromise is to have all the Multimedia untagged to suit the B&O components but you could restrict the access of the untagged network say to one port of the router..

I do see the issue.

So there’s no way to put all B&O devices on their on VLan?

Why not create a VLAN for B&O only?

We are using an HPE ARUBA 5400 series switch. We already make use of tagged and untagged VLAN. However - we give it a try with some Layer 2 approach. I'll post any result here. Most likely by the end of the week.

Thanks for the reply!

Cheers
