3.1 Introduction to DHCP Client
After you specify a VLAN interface as a DHCP client, the device can use DHCP to
obtain parameters such as IP address dynamically from the DHCP server, which
facilitates user configuration and management.

3.2 Introduction to BOOTP Client
After you specify an interface as a Bootstrap Protocol (BOOTP) client, the interface can
use BOOTP to get information (such as IP address) from the BOOTP server, which
simplifies your configuration.
Before using BOOTP, an administrator needs to configure a BOOTP parameter file for
each BOOTP client on the BOOTP server. The parameter file contains information such
as MAC address and IP address of a BOOTP client. When a BOOTP client sends a
request to the BOOTP server, the BOOTP server will search for the BOOTP parameter
file and return it to the client.
A BOOTP client dynamically obtains an IP address from a BOOTP server in the
following way:
1) The BOOTP client broadcasts a BOOTP request, which contains its own MAC
address.
2) The BOOTP server receives the request and searches for the corresponding IP
address according to the MAC address of the BOOTP client and sends the
information in a BOOTP response to the BOOTP client.
3) The BOOTP client obtains the IP address from the received response.
