Optionally, enable hybrid authentication, which
allows RADIUS filter-ID and
tunnel attributes to be used to dynamically assign policy roles and
VLANs to authenticating users (see Applying Policy Using Hybrid Authentication Mode).
Optionally, set captive portal to use HTTP
redirection to force a client‘s web browser to be redirected to a
particular administrative web page for authentication purposes (user
login and password), payment (for example, at an airport hotspot), or
use-policy enforcement (installing necessary software, agreeing to
terms of service (TOS), etc.) (see Captive Portal Redirection and Setting Up Captive Portal Redirection).
