4.3 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.
Note:
Because a DHCP server can interact with a BOOTP client, you can use the DHCP
server to assign an IP address to the BOOTP client, without needing to configure any
BOOTP server.

4.4 Configuring a DHCP/BOOTP Client

Follow these steps to configure a DHCP/BOOTP client:
Enter system view
Enter VLAN interface view
Configure the VLAN
interface to obtain IP
address through DHCP or
BOOTP
To do...
system-view
interface vlan-interface
vlan-id
ip address { bootp-alloc
| dhcp-alloc }
Chapter 4 DHCP/BOOTP Client Configuration
Use the command...

Required
By default, no IP address
is configured for the VLAN
interface.
