BOOTP client configuration only applies to 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.
z
You are not recommended to enable both the DHCP client and 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.

BOOTP Application
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, DHCP is more suitable.
