Configuring IP Parameters

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 (for
example, through Telnet, the embedded Web server, the arp and
ping commands, and HP management software), or they can be
automatically downloaded using DHCP or BOOTP each time the
print server is turned on. For configuration methods, see
Chapter
3.
When powered on, a new HP Jetdirect print server that is unable
to retrieve a valid IP address from the network will automatically
assign itself a default IP address. The default IP address will depend
on the type of network to which the print server is connected. On a
small private network, a technique called link-local addressing is
used to assign a unique IP address in the range of 169.254.1.0 to
169.254.254.255, which should be valid. On a large or enterprise
network, a temporary address of 192.0.0.192 will be assigned until
it is properly configured for your network. The IP address
configured on your print server may be determined by inspecting
the Jetdirect configuration page for the print server.

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
to configure.
