AMX SVSi N2300 w/ M4300

Hi nmarques 

Thank you for your message, very practical to have your tech support file here. Sorry about your issue, be sure we are going to help you fix it right away. M4300 was tested with AMX on all points out of the box with default configuration (VLAN 1) so when creating another VLAN, exact same parameters must be like default VLAN 1.

The symptoms you are reporting and the logs for "timer expiry/removing membership" would indicate a deficiency with the IGMP max times. Like if the switch was "stopping" the stream for a moment until a new unsollicited report (join) is coming. You don't use the default value for IGMP Snooping and the IGMP Queries times, I can see it in your configuration.

Could you come back to the default values?

Typically for the IGMP Snooping VLAN Configuration:

set igmp groupmembership-interval 5 600
set igmp maxresponse 5 120

Typically for the Querier Configuration:

set igmp querier query-interval 30
set igmp querier timer expiry 100

Everything else seems pretty normal so I would like to see if the above is fixing your issue. Of course, if you want we can directly work on your configuration file if you send it to us at ProAVDesign@netgear.com. Just export it using Maintenance\Export\HTTP File Export\Text Configuration. One our our ProAV Engineers will directly make the changes in the configuration file and return it to you. If not successful, we will schedule a Zoom call and assist you hands-on asap.

Please let us know, I hope this helps -

Regards,
