Network Architecture with 4 Power Beam 300 radios and Three Switches
I am trying to set up a proof of principle demo using 4 Ubiquiti Power Beam 300 radios in a PTP backhaul with a relay site.  I have three Netgear 105eV2 switches with VLANs per AREDN docs. My questions are:
  • Do the settings look reasonable per the drawing attached?
  • Is this the proper way to put the radios back to back since they only have one Ethernet connection?
  • Can I run the relay switch in a "dumb switch" without the VLANS?
  • What is the IP relationship between the Radio and the Switch.  Is the switch receiving DHCP from the radio?
Thanks for the help.  This is a great forum.

Four radios and three switches

Do the settings look reasonable per the drawing attached?
Yes.

Is this the proper way to put the radios back to back since they only have one Ethernet connection?
That is 'a' proper way. That is a good way because you will be able to expand the PtP site
with cameras or RPis or ...
If you are not going to expand the PtP site:
The back-to-back radios could be connected with a simple ethernet cable between the POE's LAN port.

Can I run the relay switch in a "dumb switch" without the VLANS?
Yes. You may even obit the switch. See above.

What is the IP relationship between the Radio and the Switch. Is the switch receiving DHCP from the radio?
The switches do not request nor require an IP address of itself.
The "Client's WiFi" devices' WAN port will request (DHCP) an IP address from the VLAN connected node.

Actually, in your proof-of-principle, no switches are needed. Neither VLAN nor simple.
The WiFi router's WAN ports simply connect to the POE's LAN ports.
In this scenario, access will be by associating with the WiFi routers' AP or LAN ports only.

PTP Link with relay
Thanks very much for the reply Chuck.  We will expand the network in the future and it sounds reasonable that this can help.  You expertise is greatly appreciated.

If you don't have a need to
If you don't have a need to put any clients in the middle, you can just run a cable between the power injectors for the hop in the middle. Do not put a dumb switch in the middle. Use a small smart switch like the Ubiquiti EdgeRouter X or another compact managed 802.1q capable switch. The difference is that you'll have a cost of 1.0 on the hops, whereas with the smart-switch you'll see a cost of 0.1 per ethernet hop, and the ability to "add LAN clients" to either of the two radios or both. Two PtP hops isn't going to show you what it can do like a pair of PtP and three clients. The caveat here is that you're planning to connect a wireless access point to a radio, which has the effect of allowing any station to communicate with AREDN, as opposed to using AREDN firmware in radios as clients. Let me know if I can be of assistance or introduce you to others in the area who may assist your exploration. 73, Kris KE4AHR Birmingham, AL
