Usage guidelines
The DHCP server fills the customized option with the specified ASCII string, hex string, or IP addresses,
and sends it in a response to the client.
If you use the option command with the same code specified, the most recent configuration takes effect.
You can customize options for the following purposes:
• Add newly released options.
• Add options for which the vendor defines the contents, for example, Option 43.
