Failure to Manage CPE Using CWMP

Failure to Manage CPE Using CWMP


The fault symptoms are as follows:
  • The router cannot set up a connection with the ACS.
  • The ACS fails to issue configurations to the router.


  1. Check that there is a reachable route between the router and ACS.

    Run the ping command on the router to ping the ACS.

    • If the ping fails, check the route configuration.
    • If the router can ping the ACS, go to step 2.

  2. Verify the CWMP settings on the router.

    Run the display cwmp configuration command to check whether the CWMP function is enabled and the ACS's URL, user name, and password are correctly set.

    <Huawei> display cwmp configuration
      CWMP is enabled
      ACS URL:               
      ACS username:                    hwcpe
      ACS password:                    %$%$gw1.QU~4M1I@RDF>b/VP,@7.%$%$
      Inform enable status:                 disabled
      Inform interval:                      600s
      Inform time:                          -
      Wait timeout:                         30s
      Reconnection times:                   3

    If the CWMP settings are incorrect, modify them based on Table 5-4, and run the undo cwmp enable and cwmp enable commands to re-enable the CWMP function.

    Table 5-4  CWMP settings
    Item Method

    Configure the URL used by the router to connect to the ACS. Run the cwmp acs url url command in the CWMP view.
    Configure the user name used by the router to connect to the ACS. Run the cwmp acs username username command in the CWMP view.
    Configure the ACS's password used by the router to connect to the ACS.
