Configuring Ip Parameters - HP Jetdirect 250M User Manual

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
Configuration.
Note If the HP Jetdirect print server is not configured with
an IP address within two minutes after power on, a
default value of 192.0.0.192 will be assigned. Because
this address is not valid, it should be reassigned with a
valid IP address.
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.
