Using a Vendor Class

It is recommended to define a vendor class on the DHCP server, thus enabling server and
phone to exchange vendor-specific data exclusively. The data is disclosed from other clients.
In the following, the configuration of vendor classes is explained both for a Windows DHCP
Server and for Unix/Linux.
Configuration of the Windows DHCP Server
For DHCP servers on a pre-SP2 Windows 2003 Server:
>
Windows 2003 Server contains a bug that prevents you from using the DHCP
console to create an option with the ID 1 for a user-defined vendor class. In-
stead, this entry must be created with the netsh tool in the command line (DOS
shell).
You can use the following command to set the required option (without error
message), so that it will appear in the DHCP console afterwards:
netsh dhcp server add optiondef 1 "Optipoint element 001"
STRING 0 vendor=OptiIpPhone comment="Tag 001 for Optipoint"
The value "Siemens" for optiPoint Element 1 can then be re-assigned using the
DHCP console.
This error was corrected in Windows 2003 Server SP2.
1. In the Windows Start menu, select Start > Programs > Administrative Tools > DHCP.
2. In the DHCP console menu, right-click the DHCP server in question and select Define
Vendor Classes... in the context menu.
3. A dialog window opens with a list of the classes that are already available.
