37 BOOTP CLIENT C ONFIGURATIONWhile configuring a bootstrap protocol (BOOTP) client, go to these sections forinformation you are interested in:■ “Introduction to BOOTP Client” on page 605■ “Configuring an Interface to Dynamically Obtain an IP Address throughBOOTP” on page 606■ “Displaying and Maintaining BOOTP Client Configuration” on page 606■ “BOOTP Client Configuration Example” on page 606n ■ BOOTP client configuration only applies to Layer 3 Ethernet interfaces(including sub-interfaces) and VLAN interfaces.■ If several VLAN interfaces sharing the same MAC address obtain IP addressesthrough a BOOTP relay agent, the BOOTP server cannot be a Windows 2000Server or Windows 2003 Server.■ You are not recommended to enable both the DHCP client and the DHCPSnooping on the same device. Otherwise, DHCP Snooping entries may fail tobe generated, or the BOOTP client may fail to obtain an IP address.Introduction to BOOTPClientBOOTP Application After you specify an interface of a device as a BOOTP client, the interface can useBOOTP to get information (such as IP address) from the BOOTP server, whichsimplifies 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 originates a request to the BOOTP server, the BOOTP server willsearch for the BOOTP parameter file and return the corresponding configurationinformation.Because you need to configure a parameter file for each client on the BOOTPserver, BOOTP usually runs under a relatively stable environment. If the networkchanges frequently, Dynamic Host Configuration Protocol (DHCP) is applicable.n Because a DHCP server can interact with a BOOTP client, you can use the DHCPserver to configure an IP address for the BOOTP client, without any BOOTP server.
