Restrictions for Multiservice Activation in Access-Accept Message
If one of the service activations fails, all unprocessed services from the Access-Accept message will be ignored, and any services from the Access-Accept message that have been activated will be deactivated.
A two-stage application process exists when applying a quality of service (QoS) policy via a service in an Access-Accept message. The first stage involves parsing the policy and sending the policy value to the dataplane. The second stage involves the application of the QoS policy on the dataplane. In the instance where stage one is completed successfully, but stage two fails, the relevant service can indicate that the activation was successful.
