The Cisco WLC is great at many services, but providing historical information is not one of them. Cisco would refer you to Prime Infrastructure or DNA Center for historical WLC, client or AP information. And collecting data is the strong point of these other products. The Reports section over at Prime Infrastructure is loaded with all sorts of archived information and statistics and the landing page broadcasts loudly where potential trouble spots are at. But what if you don't have easy access to Prime or DNA Center? One useful feature if you manage hundreds of Access Points is the AP Join information found under the Statistics category. Here the last known join time of an AP is recorded as well as its current status of Joined/Not joined. If you start seeing complaints about poor wireless or for just a quick health checkup of the Access Points this is a great place to check out right from the WLC homepage.
