Redirecting Subscriber Traffic Using Intelligent Service Gateway Layer 4 Redirect
You may want to configure a method of activating the service policy map; for example, control policies
can be used to activate services.
Configuring Layer 4 Redirection in a Service 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 one time in a profile to define different types of redirections for a session and can be
used in both user and service profiles simultaneously.

DETAILED STEP
Command or Action
Step 1
Add the Layer 4 Redirect VSA to the user profile or
subscriber profile on the AAA server.
Example:
Cisco-AVPair = "ip:l4redirect=redirect to
{group server-group-name | ip ip-address [port
port-number]} [duration seconds] [frequency
seconds]"
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.
