H3C Technologies H3C MSR 50 - Manual (Page 93)

ACS may assign some ACS and CPE attributes to the CPE, depending on the CWMP implementation in
your network. Support for these configuration modes varies with attributes. For more information, see
"
Configuring CWMP at the CLI ."
Configuring ACS and CPE attributes through ACS
An ACS performs autoconfiguration of a CPE through remote management. For the primary configurable
parameters, see "Autoconfiguration."
Configuring ACS and CPE attributes through DHCP
You can configure ACS parameters for the CPE on the DHCP server by using 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 H3C device 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 length 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, configure the ACS address as http://169.254.76.31:7547/acs, username as 1234, and
password as 5678, as follows:
<Sysname> system-view
[Sysname] dhcp server ip-pool 0
[Sysname-dhcp-pool-0] option 43 hex 0127 68747470 3A2F2F31 36392E32 35342E37 362E3331
3A373534 372F6163 73203132 33342035 3637 38
In the option 43 hex command:
• 27 indicates that the length of the subsequent hexadecimal strings is 39 characters.
• 68747470 3A2F2F31 36392E32 35342E37 362E3331 3A373534 372F6163 73 corresponds to
the ACS address http://169.254.76.31/acs.
• 3132 3334 corresponds to the username 1234.
• 35 3637 38 corresponds to the password 5678.
• 20 is the end delimiter.
