Configuring the CWMP connection interface
A CWMP connection interface is an interface that connects a CPE to the ACS. The CPE sends an Inform
message carrying the IP address of the CWMP connection interface, and asks the ACS to establish a
connection through this IP address; the ACS will reply the CPE with a response message to this IP address.
Generally, the system automatically obtains a CWMP connection interface through a certain mechanism.
However, if the obtained interface is not the one that connects the CPE to the ACS, the CWMP
connection will fail to be established. In this case, you must specify the CWMP connection interface
manually.
