NAX Traffic crushing network
|
OK, we have a take over site that we are partnering with the original integrator that lost his installer/programmer.? The system was designed around a SWAMP +2 expanders linked via fiber.? Due to the inability to get the extenders, they upgraded to using 3 DM-NAX units on a flat network.? The house network is all unifi, accept for the router which is a Ubi edge router.? The issue that I am seeing, is like death by a 1000 cuts.? It doesn't show up initially, but when it does it will progressively get worse.? The NAX starts crushing the broadcast traffic on the network, which in turn screws with otherwise stable peripherals.? Wifi speeds go in the tank, crestron peripherals, like the CAEN-BLOCK-CENCN2's show online but none of the CLX modules have net lights.? Network printers stop working and other misc issues.
Just wondering if it is the Unifi or if we were to VLAN for connection to the 2nd ethernet port on the NAX would fix the issue.? Thoughts, knowledge or suggestions.? This site is 4 hours away on the tip of a peninsula and I will be going back up to complete this week.? Just wondering if I should be bringing parts. |
¿ªÔÆÌåÓýThe Unifi switches will not handle anything NVX or NAX.? Those switches will need to be replaced in order for the network to stay up. ? Pat M ? ?

Hey John,
I haven't fully thought this thru yet, but I think that if you just set up the streaming ports on the NAX units to a separate switch and then use the other/non-streaming ports for control on the main network - basically a hardware wall between the two communication types... This is not the ultimate solution, but it could get you done for now... Tom Brady (not the Quarterback!) at Crestron would be the guy to review this with, Send me an email if you want his contact info... |

It is only Ubiquiti's Unifi line that cannot handle multicast traffic. I have several NVX installations using Ubiquiti's Edge line with no issues.? I would imagine that NAX traffic would not be quite as taxing as NVX.

However, it is best to route all multicast traffic through a single switch as there is no IGMP snooping on multicast router ports. If you have several switches, you have to make sure there is sufficient bandwidth on the uplink ports to handle all multicast traffic.? For NVX you will quickly run out of bandwidth on those uplink ports. casey@...

NAX and NVX are essentially the same in the network guidelines for switch configurations. When they were initially released I was told to use the NVX documentation for switch config. There's a lot of NAX traffic, especially when you have multiple units because every input and every zone output is a stream (18 per unit), which I believe is on by default. You can defeat this in the NAX setup by turning off auto initiation, in effect lessening the traffic.? You still need a capable and properly configured network but this might get you over the hump.
