Redirecting Unauthenticated Subscriber Traffic: Example
In the following example, Layer 4 redirection is configured in the service policy map BLIND-RDT. This
policy is applied to all sessions at session start and redirects subscriber TCP traffic to the server group
called PORTAL. At account log-in, the subscriber is authenticated and the redirection is unapplied.
Service-policy type control DEFAULT-IP-POLICY
