Configuring CWMP

CWMP is available in release 231 1P04 and later versions.

Overview

CPE WAN Management Protocol (CWMP), also called "TR-069," is a DSL Forum technical specification
for remote management of home network devices.
The protocol was initially designed to provide remote autoconfiguration through a server for large
numbers of dispersed end-user devices in DSL networks. However, it has been increasingly used on other
types of networks, including Ethernet, for remote autoconfiguration.

CWMP network framework

Figure 1 shows a basic CWMP network framework.

A basic CWMP network includes the following network elements:
• ACS—Autoconfiguration server, the management device in the network.
CPE—Customer premises equipment, the managed device in the network.
•
DNS server—Domain name system server. CWMP defines that the ACS and the CPE use URLs to
•
identify and access each other. DNS is used to resolve the URLs.
DHCP server—Assigns ACS attributes along with IP addresses to CPEs when the CPEs are powered
•
on. DHCP server is optional in CWMP. With a DHCP server, you do not need to configure ACS
attributes manually on each CPE. The CPEs contact the ACS automatically when they are powered
on for the first time.
The device is operating as a CPE in the CWMP framework.
