TCP/IP Configuration 27
When the HP JetDirect print server is powered on, it broadcasts a
BOOTP request that contains its MAC (hardware) address. A
BOOTP server daemon searches the
/etc/bootptab
file for a
matching MAC address, and if successful, sends the corresponding
configuration data to the JetDirect print server as a BOOTP reply.
The configuration data in the
/etc/bootptab
file must be properly
entered. For a description of entries, see “Bootptab File Entries”.
The BOOTP reply may contain the name of a configuration file
containing enhanced configuration parameters. If the HP JetDirect
print server finds such a file, it will use TFTP to download the file
and configure itself with these parameters. For a description of
entries, see “TFTP Configuration File Entries“. Configuration
parameters retrieved via TFTP are optional.
Note HP recommends that the BOOTP server be located
on the same subnet as the printers it serves.
BOOTP broadcast packets may not be
forwarded by routers unless the routers are
properly configured.
CAUTION Community names (passwords) for your printer are
not secure. If you specify a community name for
your printer, select a name that is different from
passwords used for other systems on your network.
