The ISG copies the service policy named Parent currently applied to the session and creates a transient
copy named New_Parent. While the parent shaping rate, as previously shown, changes to 120,000, the
shaping rate displayed in the transient New_Parent policy is the old rate of 10,000, as seen in the
following example. The child policy remains unchanged.

Setting the Shaping Rate Using a CoA Message

This configuration example uses a RADIUS CoA message to change the shaping rate of a session and is
based on the following ISG configuration:
ISG Original Policy
class-map match-any Premium
!
policy-map Child
!
policy-map Parent
!
ip access-list extended Premium_Dest
permit ip any 192.168.6.0 0.0.0.255
permit ip any 192.168.5.7 0.0.0.64
The following Cisco VSA is configured in a user profile on RADIUS. This VSA adds the class-default
class to the QoS policy attached to the subscriber session for outbound traffic and shapes the
class-default class to 120,000 bps.

The ISG receives the following RADIUS CoA message. Notice that the above Cisco VSA configured in
the user profile is present in the Access-Accept message.
