CWMP configuration methods

Configuring ACS and CPE attributes through DHCP

In a CWMP network, the DHCP server is mainly used to notify the ACS location and authentication
information to the ACS. DHCP server configuration includes the following tasks:
Configuring a DHCP address pool for allocating IP addresses to CPEs.
•
• Configuring the DNS server.
Configuring the Option 43 field to notify the ACS information to CPEs.
•
The following describes how to configure the option 43 field:
You can configure ACS parameters for the CPE on the DHCP server through DHCP Option 43. When
accessed by the CPE, the DHCP server sends the ACS parameters in DHCP Option 43 to the CPE. If the
DHCP server is an HP switch that supports DHCP Option 43, you can configure the ACS parameters at
the CLI with the command option 43 hex 01length URL username password, where:
length is a hexadecimal string that indicates the total length of the URL, username, and password
•
arguments. No space is allowed between the 01 keyword and the length value.
URL is the ACS address.
•
username is the ACS username.
•
• password is the ACS password.
When you configure the ACS URL, username, and password, follow these guidelines:
The three arguments take the hexadecimal format and the ACS URL and username must each end
•
with a space (20 in hexadecimal format) for separation.
The three arguments must be input in 2-digit, 4-digit, 6-digit, or 8-digit segments, each separated by
•
a space.
For example, to set the ACS address to http://169.254.76.31:7547/acs, username to 1234, and
password to 5678, you can configure as follows:
<Sysname> system-view
[Sysname] dhcp server ip-pool 0
[Sysname-dhcp-pool-0] option 43 hex 0127 68747470 3A2F2F31 36392E32 35342E37 362E3331
