For example, you can use the User Class Option to configure all BluStar 8000is in the Accounting Department with differ-
ent user preferences than the BluStar 8000is in the Marketing Department. A DHCP server uses the User Class option to
choose the address pool for which it allocates an address from, and/or to select any other configuration option.
An administrator can configure the “
dhcp userclass
” parameter via the configuration files.
To Configure DHCP Option 77 User Class:
Use the following procedure to configure DHCP Option 77 User Class on the BluStar 8000i.
Using Options 159 and 160
In addition to DHCP Option 66, the BluStar 8000i also supports DHCP Options 159 and 160. The BluStar 8000i uses the
following order of pre\cedence when deriving the configuration server parameters: 43, 160, 159, 66.
An administrator can override this order of precedence by setting the
“dhcp config option override”
parameter. Set-
ting this parameter results in the BluStar 8000i only using the chosen DHCP option and ignoring the other options.
For more information about setting DHCP download preference, see
Configuration Server Download Precedence
.
To Configure DHCP Download Options on the BluStar 8000i:
Use the following procedure to configure DHCP Option Override on the BluStar 8000i:
Configuration Server Download Precedence
An administrator can set the BluStar 8000i’s download precedence to ignore DHCP,
(only during the boot when the
remote configuration server is contacted)
and
use the following precedence instead:
1.
DHCP *,
2.
Configuration URI, and then,
3.
Direct configuration.
* DHCP is first unless it is disabled (override = “-1”)
To configure the download precedence, you use the option value “-1” as the value for the “
dhcp config option override
”
parameter in the configuration files. Setting this parameter to “-1” causes all DHCP configuration options to be ignored.
Notes:
•
If the User Class is not specified (left blank) in the DHCP request packet, the BluStar 8000i does not send the User Class
DHCP Option 77.
•
Multiple User Classes inside a DHCP Option 77 are not supported.
•
DHCP Option 77 may affect the precedence of DHCP Options, dependent on the DHCP Server.
