Wireless Access

Can anybody enlighten me as to why or why I shouldn't use DHCP reservations for my APs?  Seems the management/monitoring would be much easier to with a somewhat static address.  Any caveats I'm overlooking?

Personal preference IMHO. If you want to know just what each APs IP is, or want to assign them via reservations, then that shouldn't cause any issues

The ip address of the AP in a controller-based environment does not matter, really.  The controller will have the last registered ip address of an access point if it goes down.

The biggest caveat I see is this can quickly become painful to manage in a large environment. You'd have to make sure everyone is following the same process to create the reservation and maybe more importantly, remove it when the time comes. Some sort of automation could definitely help.

Might just be easier to rely on DNS and the controller.

The Aruba system was designed specifically NOT to rely on static ip addresses or DHCP reservations  Access points automatically register in DNS via dynamic DNS.
