Huawei ONT DHCP option CWMP (acs, tr-069)

Option43 is the another way to change the ACS URL. If ACS URL is set to http://test1.com:111 but Opion43 changes it to  http://test2.com:222 . ONT will choose http://test2.com:222  to find ACS. This option43 usually be setted from the DHCP Server which offer the IP address for ONT TR069 WAN.But i don’t think you can transfer credentials.If we want our ONT can connect to an ACS.  The first thing is a TR-069 WAN which IP address should be pingable to the ACS.

ACS URL  for example: http://tr069.mgts-spdop.ru:13029

which is just contains an address and a listening port  for ACS.

ACS User name /Password are used  for HTTP-based authentication of the CPE.

Note that on a factory reset of the CPE, the value of ACS User name /Password might be reset to its factory value. If an ACS modifies the value of this parameter, it SHOULD be prepared to accommodate the situation that the original value is restored as the result of a factory reset.   

The ACS URL which we see in the WEB page .TR-098 data model defines it :

InternetGatewayDevice.ManagementServer.URL

The other parameters define in the Object of InternetGatewayDevice.ManagementServer.

Such as Username | Password  

ConnectionRequestUsername

ConnectionRequestPassword

Just refer to the ACS Username Password Connection Request User Name and Password So ACS can get or config all the parameters from the remote side by find the TR069 nodes through TR069 Method.
