We keep the wireless MAC of all radios (Cambium and Non-Cambium) in our records, and recently we have been adding some cnMaestro integration to our records system using the REST API. Unfortunately for ePMP radios, this means that I'm unable to query the wireless MAC directly since cnMaestro only allows queries for the LAN MAC.
Being able to use the wireless MAC when making requests through the cnMaestro REST API would make things a lot nicer. Right now, I have an ugly "workaround" of subtracting 1 from the MAC address if our records have "ePMP" in the model name, though if we can query with both that would be a bit more flexible.
