DTCP Messages Used for Subscriber Secure Policy
You can use DTCP to provision traffic mirroring on the router by sending DTCP messages from the mediation device to the router.
There are three types of DTCP messages:
- ADD—Triggers mirroring of subscriber secure policy sessions. You include an attribute that triggers the router to begin mirroring a subscriber session. You can also include attributes that identify where to send the mirrored session data and how to uniquely identify traffic when simultaneous intercepts are active. The ADD message also provides instructions to populate fields in the encapsulation header for packets sent to the mediation device.
- LIST—Requests information about sessions that are currently being mirrored. This information is returned in a LIST response.
- DELETE—Removes a subscriber mirroring trigger or can be used to disable all mirroring.
