When ONT receives DHCP OFFER packet with proper DHCP Option 43 to the ip-host 1 interface (WAN0 on Ethernet routers), next it configures CWMP settings.

Example string of DHCP Option 43:

http://10.10.10.10:7547/tr069;halny;HalnY*123;SNType

Where:
http://10.10.10.10:7547/tr069 – URL of ACS Server
halny – ACS platform username
HalnY*123 – ACS platform password
SNType – optional parameter, available from V3.0.18 – defines the type of SerialNumber send in inform packets. Possible values:

• MAC
• ASCII_SN
• HEX_SN

Below there is an example on Mikrotik Router
Where:

• 172.17.61.249:7547/tr069 – ACS server IP address
• halny – login
• HalnY*123 – password

Below there is example on Dasan OLT
Where:

• 172.17.61.249:7547/tr069 – ACS server IP address
• halny – login
• HalnY*123 – password

ip dhcp option format CWMP
 attr 1 length-hidden variable value string http://172.17.61.249:7547/tr069;halny;HalnY*123;SNType

ip dhcp pool hlmgmt
