300-120 WLSI: Implementing Cisco Wireless Advanced Solutions

A controller-hosted internal LWA portal uses the built-in login pages and web server, so it can be deployed quickly, requires no separate external portal infrastructure, and is comparatively simple to configure and operate. Those properties make it fast, inexpensive, and easy. Scalability is not an inherent advantage because portal hosting and processing remain tied to controller capacity; use-case-specific portals generally require customized or external portal hosting.
