Figure 57: Example of Encapsulated Vendor Specific Option
Mediatrix units store one type of information in vendor specific options: IP addresses with optional port
number. The layout for storing IP addresses is explained in section
“Entering IP Addresses” on page 132 .
Vendor Class ID
When using the vendor specific option, first define a Vendor Class ID for the Mediatrix 1204 (not supported in
Windows NT servers). A Vendor Class ID can be used by DHCP clients to identify their vendor type and
configuration. When using this option, vendors can define their own specific identifier values to convey a
particular hardware or operating system configuration or other identifying information.
Where vendor classes are used, the DHCP server responds to identifying clients by using option code 43, the
reserved option type for returning vendor specific information to the client.
DHCP servers that do not interpret this option type are expected to ignore it when it is specified by clients.
Please refer to your DHCP server’s documentation to learn how to create a new vendor class.
Creating Vendor Specific Information
Once the Vendor ID Class is created, place the proper values in the 43 option of the DHCP server. The 43
option contains sub-options that are encapsulated (according to the format described in RFC 2132).
If the option is not in the DHCP server, the Mediatrix 1204 uses an invalid value (0.0.0.0:0).
Please refer to your DHCP server’s documentation to learn how to create vendor specific information. See
“Entering IP Addresses” on page 132 for more details on the syntax to use.
Site Specific Options
Site specific options are non-standard DHCP options specific to the network where the Mediatrix 1204 is used.
You are responsible to allocate an option number (between 128 and 254) for each information element to be
stored.
Mediatrix units store one type of information in site specific options: IP addresses with optional port number.
The layout for storing IP addresses is explained in section
“Entering IP Addresses” on page 132 .
Figure 58 is an example of site specific option #146, containing address 192.168.0.1.
Figure 58: Site Specific Option Example
When using the site specific option, you can place the values in the site specific options of your choice in the
DHCP server. You must then enter the values in the proper MIB variables.
Please refer to your DHCP server’s documentation to learn how to create site specific information. See
“Entering IP Addresses” on page 132 for more details on the syntax to use.
