Obtaining An Ip Address Dynamically; Protocols And Standards; Configuring An Interface To Dynamically Obtain An Ip Address Through Bootp - 3Com 4500G Family Configuration Manual

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.

Obtaining an IP Address Dynamically

A DHCP server can take the place of the BOOTP server in the following dynamic IP address
acquisition.
A BOOTP client dynamically obtains an IP address from a BOOTP server in the following steps:
1) The BOOTP client broadcasts a BOOTP request, which contains its own MAC address.
2) The BOOTP server receives the request and searches the configuration file for the corresponding
IP address and other information according to the MAC address of the BOOTP client. The BOOTP
server then returns a BOOTP response to the BOOTP client.
3) The BOOTP client obtains the IP address from the received response.

Protocols and Standards

Some protocols and standards related to BOOTP include:
RFC 951: Bootstrap Protocol (BOOTP)
RFC 2132: DHCP Options and BOOTP Vendor Extensions
RFC 1542: Clarifications and Extensions for the Bootstrap Protocol
Configuring an Interface to Dynamically Obtain an IP Address
Through BOOTP
Follow these steps to configure an interface to dynamically obtain an IP address:
To do...

—
Required
By default, an interface does
not use BOOTP to obtain an IP
address.
