M4300-28G-PoE+ & Tivo
Greetings - We just upgraded from a M4100 to the M4300 (GSM4328PB), flashed the latest firmware on the 4300 to 12.0.2.20. We have a Tivo Bolt and a number of Tivo Mini Vox 4K's at our facilit...
Thanks to Laurent's help we solved the problem. Great support and incredibly responsive.
For future reference and for anyone coming across this thread - for Tivo to work across an M4300 you need to disable IGMP snooping and MLD snooping. Tivo, like a lot of consumer IOT devices, assumes a flat, "stupid" network for discovery.
Hi Jon
There must be IGMP snooping still going on that is preventing TIVO required "flooding". I am sorry about that, but we will need your tech-support file for further troubleshooting on our side. Can you export this file from the switch and send it to me using Private Message?
Please refer to this KB for exporting the tech-support file:
- Log in to the command line interface of the switch and from enable mode run the command show tech-support.
- Using GUI/Web interface, go to Maintenance - Upload / Export - HTTP File Upload / HTTP File Export.
- In the File Type drop-down menu, choose Tech Support and click Apply.

Hi Jon,
Thank you very much for all of your collaboration during the troubleshooting. We have learned something and this will be very useful for the Community.
M4300 models are NETGEAR top-of-the-line 1G, 10G and 40G switches with stacking and NSF (non-stop forwarding). Main applications include server and storage interconnect, convergent access layer and SMB core. But, Pro-AV is another core application for M4300s. These switches come with pre-configured L2 multicast and this is unique in the market, because it streamlines audiovisual deployments: video-over-IP endpoints largely rely on IGMP Snooping, Querier, Fast Leave etc. for transporting video streams over Ethernet networks. As a Founding Member of the SDVoE Alliance, NETGEAR commits to the SDVoE standard and all Pro-AV alliance members can leverage M4300 switching products that are easy to set up and use to provide the backbone network for their audio-video products.
Thanks to you, Jon, we discovered that IGMP and MLD Snooping features that are enabled by default in M4300 models, interfere with Tivo "consumer-grade" solutions that are not IGMP compliant.
Here are the necessary steps for removing IGMP and MLD preconfigured features from M4300:
- Using the Web GUI for instance, Switching \ Multicast \ IGMP Snooping \ Querier VLAN Configuration: delete the line "VLAN ID 1 - Querier Mode Enable - Querier VLAN Address 0.0.0.0"
- Switching \ Multicast \ IGMP Snooping \ Querier Configuration: set "Disable" for "Querier Admin Mode"
- Switching \ Multicast \ IGMP Snooping \ IGMP VLAN Configuration: delete the line "VLAN ID 1 - Admin Mode Enable - Fast Leave Admin Mode Enable etc."
- Switching \ Multicast \ IGMP Snooping \ Configuration: set "Disable" for "Admin Mode" and for "Validate IGMP IP header"
- Switching \ Multicast \ MLD Snooping \ Configuration: set "Disable" for "Admin Mode" and for "Proxy Querier Mode"
- Switching \ Multicast \ MLD Snooping \ MLD VLAN Configuration: delete the line "VLAN ID 1 - Fast Leave Admin Mode Enable etc."
- Maintenance \ Save Config: check the box "Saving all applied changes" and click APPLY at the bottom right
Thanks again, Jon!
