3.7 Setting Up via BOOTP server

The TCP/IP BOOTP daemon on the server supports one or more remote devices. When the PrintServer is powered on, it broadcasts an initialisation request to all LAN systems. The BOOTP server receives the hardware address and looks for a match of the hardware address in the BOOTPTAB file. The BOOTP server has a BOOTPTAB file which is a correspondence file for hardware addresses and IP addresses. When the matching hardware address is located, the BOOTP server sends back (using UDP protocol) an IP address, a subnet mask and other information to the PrintServer in order to activate the unit. The data flow is as follows:

1.Upon startup, the remote device broadcasts its MAC address. (The universal MAC address is stated on the rear panel of the remote device). Upon receipt of this broadcast, the BOOTP server makes a reply.

2.The BOOTP daemon searches for a corresponding MAC address in the BOOTPTAB configuration file. If a match is found, the BOOTP daemon returns an IP address and other pieces of information defining the unit in the network.

BOOTPTAB Device Entry

Each device has its own special entry. In this entry the name of the device, MAC address etc. are given. References may also be given to a bootfile (bf).

NOTE: Do not confuse BOOTPTAB file with bootfile (bf).
