Configuring Acs Attributes; Configuring The Preferred Acs Attributes - HP 5920 Configuration Manual

Configuring ACS attributes

You can configure two sets of ACS attributes for the CPE: preferred and default.
• The preferred ACS attributes are configurable from the CPE's CLI, the DHCP server, and ACS. For
an attribute, the CLI- and ACS-assigned values have higher priority than the DHCP-assigned value.
The CLI- and ACS-assigned values overwrite each other.
The default ACS attributes are configurable only from the CLI.
•
The CPE uses the default ACS attributes for connection establishment only when it is not assigned a
preferred ACS URL from the CLI, ACS, or DHCP server.

Configuring the preferred ACS attributes

Assigning ACS attributes from the DHCP server
You can use DHCP option 43 to assign the ACS URL and ACS login authentication username and
password.
If the DHCP server is an HP device, you can configure DHCP option 43 by using the option 43 hex
01length URL username password command.
length—A hexadecimal number that indicates the total length of the length, URL, username, and
•
password arguments, including the spaces between these arguments. No space is allowed
between the 01 keyword and the length value.
URL—ACS URL.
•
username—Username for the CPE to authenticate to the ACS.
•
password—Password for the CPE to authenticate to the ACS.
•
NOTE:
The ACS URL, username and password must use the hexadecimal format and be space separated.
The following example configures the ACS address as http://169.254.76.31:7547/acs, username as
1234, and password as 5678:
<Sysname> system-view
[Sysname] dhcp server ip-pool 0
[Sysname-dhcp-pool-0] option 43 hex
