A switch in line breaks the capabilities of the backhaul to drop the Ethernet to force the IGP to reconverge immediately.

If I had to guess when someone says they don’t want a switch up top, its probably because of a practical consideration. Its why we didn’t put Netonix up there. We wanted simple. The “switch” part of the S16 is non “thing” to us. The VLANs are needed only because BHs are in it and OSPF needs to have an interface to address, etc. Rip apart and S16 and add Sync Forrest !

What I keep hearing from customers is that they want to run a multistrand cable up the tower and have an all in one box at the top which they terminate the cable into, hook up power to it, and then run short jumpers to their radios. I've heard this from enough different customers that it seems like a common desire. They all seem to want the box to do media conversion and power injection and sync, with remote control and not much more. When quizzed about just doing a switch and an injector up top, they all expressed how this was unacceptable. At this point I'm looking at feasability. I'm not sure if this will ever see the light of day, a lot depends on the amount of R&D required.

We have a handful of 450s, 25 320s, and a dozen or so 900s where we use the SyncBox. Been very pleased so far with the reliability of the S16 POE. We VLAN APs in one group and BH’s each on their own VLAN, and bring it down the fiber. If we have other devices with fiber, we bring them down on their own fiber (off the same MST). Of course there is core router with fiber inputs only being used (with the exception of the sitemonitor which I may have to buy a media converter for just to isolate the electrical connection into the router. So, as far as anything up top, I would think it would have to be some form of switch, or it would be quite kludgy.

I've torn a couple apart that use a fairly easy to use chipset. But only available in commercial temperature range. Some of the battle here is figuring out the vendors who do this type of stuff. I want to avoid switches since I want this as transparent as possible, but I might end up having to go there. I have another secret weapon in my arsenal but I'm hoping I don't have to go there since that's more software and software takes time.

I'm looking at various options to build a tower-top box to simplify the fiber up the tower with syncronized radios at the top.. Think a multiport ubiquiti fiberpoe with sync over power and a gps receiver built in, along with tower-top management. I don't want to include a switch up top - most people want as little as possible up there, and I'd rather keep the whole thing as simple as possible - I'd rather just use a copper-to-sfp chipset, but I haven't found any which I feel comfortable integrating. So I need to tear some more of the units apart to figure out what chipsets are available. -forrest On Thu, Mar 30, 2017 at 8:12 AM, Adam Moffett < dmmoff...@gmail.com > wrote: <blockquote> RB260.
