X435-24P-4S IGMP Query Issues

Joe10 — Tue, 22 Aug 2023 22:29:03 GMT

So we are using s X435 with the AVB feature lic installed with our new AV system. The system is using visionary duet2 encoders/decoders along with Crestron components. I setup a AV VLAN with IGMP query and snooping, but the video will not hold a signal according to AV install vendor, if only works if he supplies a IGMP query from his laptop. I assigned VLAN IP to IP 192.168.1.1. The ports not assigned to this AVB VLAN or using both our VOIP and Data VLANs.

I am not sure what we are missing. There solution is to add a router that can perform IGMP. But if I understand it right the switch should be doing this when the VLAN has an assigned IP. I have provided the outputs from these commands <sh igmp vlan TAVB>, <sh vlan tavb>, <sh port 2 info det>.

Hi @Joe10,

Regarding the show port vlan, where are connected the AVB devices ?

Are you sure for vlan TAVB tagged on the ports ?

Regarding the igmp config part, please follow the links I shared you.

The connected devices are scattered across VLAN on ports 1-22, I believe it is a total of 10 Visionary Duet encoders/decoders.

I did previously do the IGMP config stuff. Reading through your AVB links was educational but raised a lot of questions and made me question how our other AV systems are handling this as none of the network specific components are dishing out a IGMP query signal but they are a more complicated AV setup, using a mix of BIMAP, Kramer, Crestron and Extron components.

From what I can tell we will probably end up adding a router to the VLAN that can supply an IGMP query signal.

For VLAN tavb, I see that the switch is elected as querier. For simplicity, you can run this command:

show igmp vlan tavb | include Querier
Learned multicast addresses(Last Querier=x.x.x.x):
Querier UpTime: 6 days 4 hours 7 minutes 1 second

This will tell you if there is a querier for that VLAN or not. Then proceed to check the streams:

show igmp snooping vlan tavb
Router Timeout : 260 sec
Host Timeout : 260 sec
Igmp Snooping Fast Leave Time : 1000 ms

VLAN tavb (100) Snooping=Enabled
Group Sender Age
224.10.10.25 10.5.142.13 19
224.10.10.25 10.5.142.23 39
224.10.10.25 10.5.142.25 47

The last column is important here. It will count up to Query Interval : 125 sec + a max of Max Response Time : 10 sec, so between 125 and 135 seconds. If the counters carry on to more than 135, something is wrong (for "normal groups, don't mind the 239.255.255.x groups). This can also be seen in the other switches attached to the VLAN if any.

I do see some 224.0.0.251 (PTP timing) sessions that refresh after slightly longer than 135 sec, like 155 sec tops, but that seems normal. Your video and audio streams should definitely go back to 0 after reaching 125-135.

When the AV guy starts the querier on the computer, does the VLAN reported querier change? What version if IGMP do you use? This can be a major issue. Normally, IGMP v2 is the easiest to work with.

Unfortunately nothing is talking at the moment so I did not get full results. I did work with Extreme yesterday and we enabled AVB and updated to the most current version of EXOS 31.x patch 98, and they verified the query is present which is what I thought. So now I am in a holding pattern until the AV vendor can be on site again and see if anything we did makes a difference.
