DtD walkthrough?
Hello all --

I am trying to build a tower-mounted two-radio setup as described on the "channel planning" part of the AREDN site.  I need to send PoE to the 2GHz and 5GHz radios at the top of my tower.  And I need the 2GHz and 5GHz radios to mesh together, which I understand is what DtD is for.  After several days of attempts I have not had success getting the two radios to talk to each other, although I know that each one of them is running separately.

I am now trying to simply prove the DtD concept on my workbench.  I have an hAPaclite and an hAPac3, both running AREDN 3.24.10.0.  I have plugged "port 5" of each device together.  (Maybe this is called a "back-to-back" setup?)  See picture:



I can access the AREDN dashboard of each device but I cannot seem to confirm whether DtD is working.  With the radios on, the devices mesh together.  I turned off the radio on the hAPac3 so that the only possible connection would be through the CAT5 cable.  But a ping test using the tool on the dashboard shows nothing -- the only result is "Ping Terminated."

 

Pictures of the AREDN dashboards for both devices:





I have zero networking experience and there's virtually no AREDN activity where I am, so I need a lot of help -- what should I do next to try to get DtD working?

k1zk: hAP-ac-lite and hAP-ac3
Reference ac3.png and aclite.png
In aclite.png is shown an (AREDN/'mesh') RF connection between the ac-lite and the ac3,
Yet, in the ac3.png image no RF radio appears configured.
Were these 2 images saved close to the same time?

IIRC, in AREDN firmware if there is both a DtD and a RF connection to the same node,
the DtD connection will be used and the RF connection ignored.

You have sufficient equipment to join your 2 GHz and 5 GHz tower radios if you configure 2 DtD ports on your ac3.
See attached image.
Use the POE injectors that came with your 2 and 5 GHz radios.
Connect the 2 and 5 GHz radios to port 4 and 5.

I hope this helps,
Chuck
