Hi, I migrated from a WiSM2 to a 9800-40 an redid the managment-netowrk for the APs too. It was a single VLAN before, and now it is a VLAN per distribution layer, were the L2 for the buildings on that distribution layer usually terminate. It is IPv6 only now, so a /64 per VLAN, and the APs for the buidlings the DL is responsible for in it (depending on size, anything from 100-250 APs).
Controller address gets to APs via DHCPv6.

Part of this upgrade will include redesigning our AP management network(s)—currently, we have about 500 APs spread across 3 different /24's. As we move towards an in-room design in our residence halls and provide denser 5GHz coverage throughout campus in the coming years, we expect the number of APs to grow by quite a bit. I am interested in how others have sized your AP management networks? I have not found any concrete guidance from Cisco and various recommendations elsewhere range from /25 to /21. Larger ranges would of course be easier to manage, but at the same time we don't want to introduce issues related to broadcast traffic. Thanks for any input that you can provide.
