11.10 CWMP
The CPE WAN Management Protocol (CWMP) is a messaging protocol designed for communication between the CPE
devices and the management system. Specifications for this protocol are written by The Broadband Forum (formally DSL
Forum) in technical reports, and the TR-069 defines the messaging format based on XML for communicating using CWMP
Up to NMS release 11.0 SP2, the discovery process and also all NMS supported operations used CLI or SNMP to communi-
cate to the devices. In NMS release 11.0 SP3 and SP5, however, TR-069 operations can be performed on a Comtrend CPE
device. (Refer to 5.7.6.) Although not all operations are implemented initially, there is a generic TR-069 client application
implemented that can be used to execute any of the TR-069 operations described in the specification.
To access this tool, select under the Tools menu CWMP Browser. Refer to the following figure.
FIGURE 11-7 CWMP Browser - Initial Screen
If any devices managed using TR-069 (Comtrend only in release 11.0 SP5) have been discovered using the NMS, they will
appear in the Device pull-down. The Connection URL is the URL on the CPE the Auto Configuration Server (ACS) can use
to initiate a connection. (This is done when using the Comtrend Boot Configurator.) Also, the IP address of the ACS (the
NMS being used) must be provisioned by accessing the device (using the client’s browser, for example). Error messages may
occur if these are not present.
The tabs and buttons follow the operations of the TR-069 specification.
