ENWW TCP/IP Overview 89

Configuring IP Addresses

TCP/IP configuration parameters (such as IP address, subnet mask,

default gateway) can be configured on the HP Jetdirect print server

in a variety of ways. These values can be configured manually

through HP-supplied software, or they can be automatically

downloaded using DHCP or BOOTP each time the print server is

turned on.

Dynamic Host Configuration Protocol (DHCP)

DHCP allows a group of devices to use a set of IP addresses that are

maintained by a DHCP server. The device or host sends a request

to the server, and if an IP address is available, the server assigns

it to that device.

BOOTP

BOOTP is a bootstrap protocol used to download configuration

parameters and host information from a network server. BOOTP

uses UDP for its transport. In order for devices to boot and load

configuration information into RAM, they must communicate

through the bootstrap protocol BOOTP as a client with their server.

To configure the device, the client broadcasts a boot request packet

containing at least the hardware address of the device (HP

Jetdirect

print server hardware address). The server answers with a boot

reply packet containing the information the device needs

configure.
