26 DHCP/BOOTP CLIENTCONFIGURATIONIntroduction to DHCPClientAfter you specify a VLAN interface as a DHCP client, the device can use DHCP toobtain parameters such as IP address dynamically from the DHCP server, whichfacilitates user configuration and management.“Obtaining IP Addresses Dynamically” on page 282 for the process of how aDHCP client dynamically obtains an IP address through DHCP.Introduction to BOOTPClientAfter you specify an interface as a bootstrap protocol (BOOTP) client, the interfacecan 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 filefor each BOOTP client on the BOOTP server. The parameter file containsinformation such as MAC address and IP address of a BOOTP client. When aBOOTP client sends a request to the BOOTP server, the BOOTP server will searchfor the BOOTP parameter file and return it to the client.A BOOTP client dynamically obtains an IP address from a BOOTP server in thefollowing way:1 The BOOTP client broadcasts a BOOTP request, which contains its own MACaddress.2 The BOOTP server receives the request and searches for the corresponding IPaddress according to the MAC address of the BOOTP client and sends theinformation in a BOOTP response to the BOOTP client.3 The BOOTP client obtains the IP address from the received response.n Because a DHCP server can interact with a BOOTP client, you can use the DHCPserver to assign an IP address to the BOOTP client, without needing to configureany BOOTP server.Configuring aDHCP/BOOTP Client Table 215 Configure a DHCP/BOOTP clientOperation Command DescriptionEnter system view system-view -Enter VLAN interface view interface Vlan-interfacevlan-id-
