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 HPE 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 0127687474703A2F2F3136392E3235342E37362E33313A373534372F61637320313233342035363738
