Configuring the CWMP connection interface
The CWMP connection interface is the interface that the CPE uses to communicate with the ACS. To establish a CWMP connection, the CPE sends the IP address of this interface in the Inform messages, and the ACS replies to this IP address.
Typically, the CPE selects the CWMP connection interface automatically. If the CWMP connection interface is not the interface that connects the CPE to the ACS, the CPE fails to establish a CWMP connection with the ACS. For example, an incorrect CWMP connection interface selection occurs when the following conditions exist:
The CPE has multiple Layer 3 interfaces.
The IP addresses of the CWMP connection interface and the ACS are not in the same subnet.
In this case, you need to perform this task to manually set the CWMP connection interface.
To configure the CWMP connection interface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CWMP view. | cwmp | N/A |
3. Specify the interface that connects to the ACS as the CWMP connection interface. | cwmp cpe connect interface interface-type interface-number | No interface is specified as the CWMP connection interface. |
