Hi
I’m new to Extreme Switches and Exos, but was recommended the product from a supplier. I’m trying to run a Riedel AES67 Network (intercom) over it.
The X440 model is the recommended and sold by Riedel themselves, but I can’t get it to work with more then 1-2 intercom panels. Everything else is reachable by the config network, problem also shifts after a new power sequence on the units.
I’ve tried to google for hours and tried different configs. At the moment I’m running only one vlan with nothing else connected to the switch.
My question is: Is there any documentation on how to configure a X440 to support AES67 traffic?
Solved! Go to Solution.

AES67 is a protocol for transmitting audio over IP, much like Dante. It has nothing to do with encryption (as I first thought, like AES128 and AES256).
I suspect the you're having IP addressing problems in your Riedel equipment. AES67 can communicate using multicast and then you can see that kind of problem if multiple sources transmit on the same multicast address. Do you have an IP addressing plan for your Riedel equipment and are you experienced in configuring and using that gear?
You need:
- One separate IP address for each AES67 box
- All IPs need to be in the same subnet (for example 10.0.0.x (x=1..254) with netmask i.e. 255.255.255.0)
- If using multicast, each sender (AES67 unit) needs to transmit each stream/channel using a separate multicast address (much like an IP address)
There should be no special config in a switch needed to support AES67 traffic except if you need IGMP snooping. In that case you need an IGMP querier, which can be the X440 switch (I think it supports it and needs no license for it). IGMP snooping with no querier is easily identified as multicast streams will work for a few minutes and then stop working, which doesn’t sound like the problem you're having.
I do hope this wasn’t too low-level. It’s hard to determine the competence level of someone with a total of 1 post 🙂

Have you already been in contact with Riedel? If they sell X440 as supported hardware, then they will know how to configure it properly. I don’t know anything about the technical details of AES67 to help you troubleshoot it.
Which firmware are you running?
