Configuring the CWMP Connection

Procedure

1. Run system-view

   The system view is displayed.

2. Run cwmp

   The CWMP view is displayed.

3. Run cwmp acs url url

   The ACS's URL to which the CPE connects is specified.

   To use the HTTPS URL, you must configure SSL authentication.

   You can also configure a DHCP option to specify the ACS URL. However, if DHCP packets carrying this option are interrupted, the ACS URL will leak, causing security risk. Use this method only in a secure network environment.

4. (Optional) Run cwmp permit interface { interface-type interface-number } &<1-5>

   Physical interfaces on the CPE to which the ACS can connect are specified.

   By default, the ACS can connect to all the physical interfaces on the CPE.

5. (Optional) Run cwmp cpe connect interface interface-type interface-number

   The CWMP connection interface is specified.

   Generally, a CPE obtains a CWMP connection interface from all the interfaces to which the ACS has reachable routes. If the obtained interface does not connect the CPE to the ACS, CWMP connection fails to be set up. Therefore, a CWMP connection interface needs to be specified manually.

6. (Optional) The CPE can use the following methods to send inform messages:
   • Sending inform messages periodically
   1. Run cwmp cpe inform interval enable

      The CPE is enabled to periodically send inform messages.

      By default, the CPE does not periodically send inform messages.

   2. Run cwmp cpe inform interval seconds

      The interval at which a CPE sends inform messages is set.

      By default, a CPE sends an inform message every 600 seconds.

   • Sending an inform message at a specified time
   1. Run cwmp cpe inform time time

      The time when a CPE sends an inform message is set.

      By default, no time is specified for the CPE to send an inform message.

   You can configure either one or both methods.

7. (Optional) Run cwmp cpe inform product-class device-type

   The actual product type of the CPE is added to the session initiated by the CPE to the ACS.

   By default, the session initiated by the CPE to the ACS contains the product type AccessRouter.

8. (Optional) Run cwmp cpe connect retry times

   The maximum number of attempts the CPE can make to retry a connection is set.

   By default, the maximum number of attempts is 3.

9. (Optional) Run cwmp cpe wait timeout seconds

   The connection timeout interval is configured for the CPE. If no data is transmitted within the timeout interval, the connection between the CPE and ACS is torn down.

   By default, connection timeout interval is 30 seconds.

10. (Optional) Run cwmp ip-change inform disable

    The device is disabled from informing the ACS of an IP address change event.

    By default, when the IP address of a device changes, the device does not inform the ACS of this event.

    This command takes effect only on IP addresses reachable to the ACS.
