9 Configuring CWMP
9.1 Overview
CPE WAN Management Protocol (CWMP) provides a general framework of unified device management, related message
specifications, management methods, and data models, so as to solve difficulties in unified management and maintenance of
dispersed customer-premises equipment (CPEs), improve troubleshooting efficiency, and save O&M costs.
CWMP provides the following functions:
 Auto configuration and dynamic service provisioning. CWMP allows an Auto-Configuration Server (ACS) to
automatically provision CPEs who initially access the network after start. The ACS can also dynamically re-configure
running CPEs.
 Firmware management. CWMP manages and upgrades the firmware and its files of CPEs.
 Software module management. CWMP manages modular software according to data models implemented.
 Status and performance monitoring. CWMP enables CPEs to notify the ACE of its status and changes, achieving
real-time status and performance monitoring.
 Diagnostics. The ACE diagnoses or resolves connectivity or service problems based on information from CPEs, and
can also perform defined diagnosis tests.
The CWMP function is supported only on AP320, AP330, AP120, AP530, AP630 (IDA) V1.0, AP630 (IODA) V1.0,
AP520 V1.0, AP530-I V2 V1.0, AP130-W V1.0, AP630 (CD), and AP520 (DA).
Cloud AC system is not supported on AP530-I v1.x, AP220-E (v2.x), AP220-E (M) (v2.x), AP620 (v2.x), AP620-H(C)
(v2.x), AP220-I, AP220-SI or AP220-E(C).
