Some key issues must be considered when designing a wireless LAN environment. First, the controller redundancy design should be carefully analyzed. Wireless LAN Controllers (WLCs) can be configured for dynamic redundancy or deterministic redundancy. With deterministic redundancy, the access point is configured with a primary controller, a secondary controller, and a tertiary controller. This requires a lot of planning but it offers good predictability and faster failover times. Dynamic controller redundancy uses Light Weight Access Point Protocol (LWAPP) to load balance access points across WLCs.
Another issue that must be analyzed in the design process involves the management of radio . . .
