Hi Guys,
I thought that I come up with this. IGMP snooping is great feature but how about adding the IGMP version and the MLD snooping version to the management interface? Recently I used Dante a lot of times and I didn’t find a convenient way to show the MDB table. I ended up using SSH and tail-f /var/log/messages to see why my Dante network isn’t working when I enable IGMP snooping. I didn’t have success yet but I’m trying.
Have a nice day,
Adam
We’ve tested Dante successfully in our own labs, so hopefully you should be able to get to the bottom of the issue. If you want to look at the current IGMP state of the switch, do “cat /var/run/igmpd-state.json | jq” and you can see what IP addresses map to what ports.
Many thanks !
I found out that the PTPv1 clock is not forwarded to my laptop where Dante controller is open. The AVIO is on port 1, the laptop is on port 9 and the uplink is 16. I figured out that the index starts at 0.
It’s not confidential so I paste the output here:
root@NFR-S16:~# cat /var/run/igmpd-state.json | jq
