Title: Dante Clock Issues
Post by: Aske Just on April 23, 2019, 09:43:00 AM
Hello!
Ive been experiencing some issues with our dante system clocked to external source.

Every hour my system loses lock on wordclock and all or most of my units is temporarily muted. This causes us to lose 1-2 sec of audio every hour. 2-3 days ago it would happen on the 36th minute mark of every hour. Today we are experiencing it on the 40th minute mark, so its drifting a bit.

Sync and Network is looking fine according to the documentation and the tools provided by the Dante Controller. How do i continue from here?

All help is welcomed warmly!

This is the output from the log:

You need to use your real name in this forum, and you need tick SYNC TO EXT in Controller; you don't specify having done that. And if you have not done Dante Certification online, you will learn a lot about Dante clocking there.

Thank you Very much sir!
I have updated my profile with my name.
The Cl3 is set to external clock in the controller.

Assuming all network settings are good. Put Wordclock directly into the pix 270 set as it as preferred master and check sync to external, uncheck the cl3 sync to external and remove the wordclock from the cl3. Be slightly nervous that you are relying on the video department for your Dante sync!

Thanks for your reply!
Before the configuration we are in now, i have tried something similar. But the pix is having some strange issues.

1. If you set the pix to external clock. It doesnt recieve any audio signals. All meters are silent.
2. If you set the pix to recieve clock/sync from dante it gives an error saying sync is not present on the current  setting?

As it is now, the pix is set to recieve wordclock from the sync in bnc on the back. The controller still says "dante" under clock. Unplugging the bnc will make it give an error. Its like the software of the pix doesnt communicate well with the rest of the dante.

Have you experienced anything like this?

Well.... Its what it says on my drivers license. Feel free to find me on facebook :(

I think i have found one, if not THE solution to my problem...

I know i said the network connection was fine, but frustrated with not having anywhere to go for clues to the source of my issue, i downloaded the software for my Yamaha Switch (SWP1-8MMF)

In there you can see bandwidth, ips and so on. I then notice alot of clients on the port that i have my Pix Recorder plugged in. I see iphones, laptops and what not....

I then see that on the back of the pix, it has been connected to our production wifi-router with a ethernet cable to the secondary dante port... Then it hits me that all the IPs on all my dante units have been dictated by the DHCP on the work, wifi. So none of them followed the 169.254.x.x but instead the subnet and vlan provided by the pfsense gateway.  The reason is probably that someone wanted to access the Pixnet Web-Ui of the pix recorder, but apparently these two ethernet ports also acts as a switch, so suddenly the entire Dante network was controlled by the DHCP server of the Pfsense.

If the pfsense was the culprit behind these hourly timeouts i dont know yet, but this is a step forward anyways! Will update when i hopefully dont see any errors again.

Thanks to everyone who has given me input in this matter.

The pfsense May be the culprit but the dhcp server probably not.  We run a mixed network that includes Dante and a dhcp server with no problems - I would look else where in your pfsense settings and consult the Audinate network info on what Dante needs....

I highly doubt that’s your problem. Worst part about how audinate teaches their classes is how they encourage everyone to use those link-local addresses. They need to work on that. You be smart to either a. USE a dhcp server (on purpose- I know, I’m a mad man), or b. assign static ips all the way around. If you assign static’s it wouldn’t  matter if someone put 1 or 20 dhcp servers on your network.

If a clock master drops out a new one should be automatically elected without any input from you.

IIRC one of the early Dante chipsets could not use Static IPs.   By the time the chipsets were updated to accommodate static IPs the SOP to use link-local had been set.

It also goes against Audinates sales pitch of it being relatively plug and play.

I had a customer recently (on their own) try to get StageMix working for a QL console, and instead of plugging the Home Router into the mixer, they pluged into the switch.   That link-local dante setup kinda went crazy.  This is of course because they only had the control room equipment on, and not the amp racks as they were just testing things.   Once it did work (or didn't, I don't know) the the router was disconnected and when the amps were turned on...nothing worked.   We don't use link local addressing for Dante chips anymore.

That’s what I’m saying, it’s fraught with errors. I think static’s are the safest but I’ve heard personally of 3-4 incidents where a rogue dhcp server made it onto a network and shut it down. Static’s are immune to the dhcp server but of course they’re more labor intensive. I always set mine up with statics.

Didn’t mean to hijack, but I think this is an important discussion when it comes to Dante.

Well i think the important part here is the "on purpose". The culprit was indeed the pfsense and the dhcp. Im not saying it wouldnt work, if set up properly, but how it ended up here was the Dante units being controlled by the´pfsense forcing ip-ranges and assigning vlan that was dedicated to the work-related wifi, and with that alot of settings not consciously meant for the dante network. Everything is working fine here now. Latency, clock and everything is in perfect order. I am back to syncing our Rsio64 form external wordclock produced by a rosendahl nanosync. That box is permanently powered and on UPS.

But again thanks to everyone helping me out, especially that guy doubting my Danish name  ;)

You could check de pfsense dhcp server lease time. My bet is it is set at 3600 secs, thus releasing the ip adres every hour.
