Control Relationship; How To Configure Cpd; Enabling Cpd Functionality - Cisco cBR-8 Configuration And Troubleshooting Manual

Control Point Discovery
3 UDP
4 IP
Note Since NLS is implemented on the UDP protocol, there is a potential of message loss. If messages are lost,
the controller will re-send the CPD request in any such event.

Control Relationship

A control relationship between a control point and a controller is identified as a function on a media flow that
passes through a control point. A control relationship is uniquely defined by a control relationship type (CR
TYPE) and control relationship ID (CR ID). The CR ID is provisioned on CMTS as well as the controller.
The table lists the supported CR TYPEs and corresponding pre-defined CR IDs
Table 19: Supported Control Relationship Types and Corresponding Control Relationship IDs
Control Relationship Type
CR TYPE = 1 (Lawful Intercept)
CR TYPE = 2 (DQoS)
CR TYPE = 3 (PCMM)

How to Configure CPD

Enabling CPD Functionality

To enable the CPD functionality, use the cpd command in global configuration mode. The CPD message
authentication is determined by NLS configuration.
