It's in the User Guide. You can use option 43, or if you set a domain via option 15 (the "Domain" field in Mikrotik DHCP) then it tries "cnmaestro.domain"

My problem turned out to be that if you've already set a URL for CnMaestro then it won't use the DHCP provided option. But in theory, if we're plugging in one at default settings it should get the URL from DHCP.

Is anybody successfully setting the CnMaestro URL via Option 43 on ePMP?

I've set up a Mikrotik DHCP server in accordance to these instructions: http://community.cambiumnetworks.com/t5/cnMaestro/Microtik-Routerboard-DHCP-configuration-for-onboarding-devices/m-p/56012#M26 <http://community.cambiumnetworks.com/t5/cnMaestro/Microtik-Routerboard-DHCP-configuration-for-onboarding-devices/m-p/56012#M26>

Option 60, 43, and Domain are all set, but the cnMaestro URL is never actually changed on the ePMP devices, neither on a DHCP renewal or a reboot. I can confirm via packet capture the options are being sent to the ePMP. I don't see any attempt to connect to the CnMaestro server on premises, but I do see them doing DNS lookups for cloud.cambiumnetworks.com.
