While configuring a bootstrap protocol (BOOTP) client, go to these sections for

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 addresses
■
through a BOOTP relay agent, the BOOTP server cannot be a Windows 2000
Server or Windows 2003 Server.
You are not recommended to enable both the DHCP client and the DHCP
■
Snooping on the same device. Otherwise, DHCP Snooping entries may fail to
be generated, or the BOOTP client may fail to obtain an IP address.
After you specify an interface of a device as a 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 originates a request to the BOOTP server, the BOOTP server will
search for the BOOTP parameter file and return the corresponding configuration
information.
Because you need to configure a parameter file for each client on the BOOTP
server, BOOTP usually runs under a relatively stable environment. If the network
changes frequently, Dynamic Host Configuration Protocol (DHCP) is applicable.
n
Because a DHCP server can interact with a BOOTP client, you can use the DHCP
server to configure an IP address for the BOOTP client, without any BOOTP server.
