CWMP configuration

CWMP overview

The CPE WAN Management Protocol (CWMP) is initiated and developed by the Digital Subscriber's
Line (DSL) Forum. CWMP is numbered TR-069 by the forum, and is thus also called the TR-069 protocol.
CWMP is designed to be applied to DSL access networks, which are hard to manage because devices
are located at the customer premise, dispersed, and large in number. CWMP makes the management
easier by using an auto-configuration server (ACS) to perform remote centralized management of
customer premises equipment (CPE).
A large-sale data center network has similar network environment as a DSL access network, so you can
use CWMP to remotely configure, manage, and maintain the switches in batches in the data center
network.
The switch support the CWMP protocol. When starting up for the first time to access the network, an H3C
switch functions as a CPE and automatically downloads the configuration file from the ACS. Compared
with traditional manual configuration, remote and unified configuration by using CWMP offers the
following benefits:
Deployment of unified configuration to switches providing the same services. This reduces
•
workloads and improves configuration deployment efficiency.
Auto-configuration of access switches. This enables the switches to access the network after startup
•
without the need of manual configuration and reduces costs.
Pre-generation of the configuration file. This reduces the error probability of manual configuration.
