I need a little nudging to the correct answer. We have grown too large to put a static IP on every customer radio. I need to start having the radios grab a DHCP address. On every tower, we have a management VLAN with a /23 of private space. The second /24 of that space is now going to be a DHCP server in the Mikrotik. APs, switches and backhauls still get statics from the first /24.
Great. What I want to do is have Sonar automatically acquire (or learn) that IP address that is served to the SM. Sonar knows about the /23 subnet. It knows about the /24 pool in that /23 subnet. It knows the DHCP server and the DHCP server identifier for that /24. It also knows the MAC address of every SM and we attach that to a customer.
So, how do I get Sonar to know that some new SM pulled 10.10.7.200 from the Mikrotik and then show me that in the inventory so we can click on it and manage the radio? I feel like I am close.
For customer IPs, we do Option 82 with a batcher and that works great but I don’t think I need to use a batcher and a DHCP script here, do I? Until now, 100% of management IPs are hard coded so this is easy - we just type the IP into Sonar for that inventory item and everything is great. Until you have 100’s and 100’s of devices out there. And we had to break up management subnets to quiet down management traffic…
