Configuring Layer 4 Redirection in a Service Profile or User Profile on the AAA
Server
The Layer 4 Redirect feature can be configured as a Cisco vendor-specific attribute (VSA) in a user or
service profile on an authentication, authorization, and accounting (AAA) server. This attribute can
appear more than once in a profile to define different types of redirections for a session and can be used
in both user and service profiles simultaneously.
SUMMARY STEPS

What to Do Next
If you configure ISG Layer 4 redirection in a service profile, you may want to configure a method of
activating the service profile; for example, control policies can be used to activate services. For more
