How to prevent NVY traffic to go out of M4300 ?
Hi I have a system where I use the M4300 for Crestron NVX system (Video over IP system). So far the NVX system on the M4300 works perfect but I have an issue. To be able to control NVX devices I...
Thank you, vincelaus
To answer your questions in the right order:
- Correct, please apply the "Video" profile to all ports. Don't create a new profile, it doesn't seem to me you need it. Instead, in the AV UI, go to Network Profiles\Configure page. Find the Configured Profiles table in the middle of the page. You should see Default VLAN 1 in the table. Use the three little dots on the right, and select Edit. In the popup edit window, find the Template dropdown menu, select it, find Video and select it. Click Apply to close the popup window. If you now see Video under "AV template" in the List of configured profiles, you're good. Click Save on the upper right.
- Yes, go to Multicast page, select the port going to the main network, and use the dropdown menu to select "Block". Click Apply. A small block icon will appear on the switch representation image, at the top of the page. Click Save (blue button) on the upper right again. So does all of it survives to the reboots.
- Yes, unlike M4250 or M4350, M4300 doesn't have Auto-Trunk and Auto-LAG enabled by default. You need to manually enable both in the AV UI. It's easy. At the top of the page "Network Profiles\Configure', toggle on Auto-Trunk. Click Save on the upper right. Next, go to Link Aggregation page, and toggle on Auto-LAG. Click Save again on the upper right.
- Auto-LAG will take care of everything for you, don't worry. Yes, for multicast, don't touch the Default L2 hashing algorithm, it's optimized to parse traffic based on multicast groups (Multicast MACs). Just connect the switches together with 2, 3, or 4 10G in between. For instance, the 2 10G copper ports using CAT6A cables. Or the 2 10G SFP+ ports using 10G DAC cables. Or all four ports all together if really you have that much traffic expected.
I think you're all set! Have a great weekend.
Hi vincelaus ,
Don't worry, it is going very simple.
Please upgrade your M4300 to the latest firmware from here M4300 FW
NETGEAR IGMP Plus prevents any flooding outside of M4250/M4300/M4350/M4500 switches, so there are two possible root cause for the flooding to the main LAN:
- Misconfiguration on the M4300 switch, maybe you created a VLAN and used port based IGMP settings instead of IGMP Plus at the VLAN level only. If so, we need to help you reconfigure, please send your tech-support file (IT GUI Maintenance\Export\HTTP File Export\tech-support in the dropdown menu; or AV UI Diagnostic\Support Diagnostics) to ProAVDesign@netgear.com with a link to this thread
- IGMP Plus is correctly configured at the VLAN level, or you just using the VLAN 1 which is already pre-configured with IGMP Plus. In that case, the network switch (main network) you are uplinking to wrongly advertizes itself as a mutlicast router, and then the M4300 switch has no choice by sending all the multicast to it. Several solutions of course, but the easiest is: go to the AV User Interface (left login when pointing your browser to the switch Management IP address), go to Multicast, select the uplink port you are using to the main network, and configure "Block Multicast" on it. Apply, then Save. There will be no multicast anymore through that port.
To your other question: No! Don't stack please. Stacking also floods multicast between switches. Please make sure you activate Auto-Trunk and Auto-LAG in your existing M4300 switch, and in your new M4300 switch. It's much better to LAG the two switches, with IGMP Plus containing the multicast just right between the two switches. Of course, please calculate how many streams will traverse and calibrate your LAG (2x10G? 4x10G?) right to allow for non-blocking communication between the two switches.
With two switches it can be very worthwhile to use the Engage controller.
Maybe a good occasion to start fresh, factory-default your existing M4300 switch, onboard the new one with it - and use Engage to configure your VLAN 1 with the Video profile all right for NVX. Auto-LAG and Auto-Trunk will do their magic!
