Usage guidelines
Upon startup, the DHCP client obtains an IP address and the specified server IP address. Then it
contacts the specified server, such as a TFTP server, to get other boot information.
If you execute this command multiple times, the most recent configuration takes effect.

Usage guidelines
The DHCP server fills the customized option with the specified ASCII string, hexadecimal number, or
IP addresses, and sends it in a response to the client.
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.
