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.
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.
This section covers these topics:

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 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.
