We deploy one AP vlan per closet to avoid spreading vlan across closets. Majority of the subnets are /27 and /26 depends on the number of APs required at that location.

We went from all of our APs in one large broadcast domain, to a bunch of much smaller segments when we moved to routed that were sized on need. Now that we are moving into the world of SDA, we are again putting them all into 1 large IP subnet. In all cases we were/are using DHCP reservations so that we know the IP/hostname of an AP. The answer to this lies in your network itself and your IPAM solution. Whatever makes sense so long as the AP can get to the controller. -- Cheers, Jeff From: The EDUCAUSE Wireless Issues Community Group Listserv <[email protected]<mailto:[email protected]>> on behalf of Donald Ambrose <[email protected]<mailto:[email protected]>> Reply-To: The EDUCAUSE Wireless Issues Community Group Listserv <[email protected]<mailto:[email protected]>> Date: Thursday, June 18, 2020 at 7:38 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Re: [WIRELESS-LAN] AP Management Network Size Caution: This email was sent from someone outside of the University of Lethbridge.

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.
