BOOTP Table File Entries
An entry in the BOOTP table file
similar to the following:
hphub16M:\
ht=ether:\
ha=080009123456:\
ip=190.40.101.22:\
sm=255.255.255.0:\
gw=190.40.101.1:\
vm=rfc1048
Definitions of the table entry fields:
hphub16M
is a user-defined symbolic name to help you find the correct section of the
bootptab file. If you have multiple hubs that will be using BOOTP to get their
IP configuration, you should use a unique symbolic name for each hub.
ht
is the "hardware type" tag. For the HP 10Base-T hubs, set this to ether (for
Ethernet). This tag must precede the ha tag.
ha
is the "hardware address" tag. Use the hub's 12-digit MAC address.
ip
is the IP address to be assigned to the hub. Enter the address in the dotted-
decimal format as shown in the example on the previous page.
sm
is the subnet mask of the subnet in which the hub is installed.
gw
is the IP address of the default router (or gateway) that allows the hub to
communicate with systems that are not on the local network segment. If there
is no default router, do no include this tag.
vm
is a required entry that specifies the BOOTP report format. For the HP 10Base-
T hubs, you must set this parameter to rfc1048.
Notes for the bootptab file:
Blank lines and lines beginning with the pound sign (#) are ignored.
Make sure you include a colon (:) and a backslash (\) as a continuation
indication at the end of each line except the last one. Each record is a
single line. The colon (:) separates fields in the record. The backslash (\)
indicates the current record continues on the next line as if there were no
carriage return and linefeed characters.
Spaces are not allowed between the characters on a line.
Names, such as hphub16M must begin with a letter and can only contain
letters, numbers, periods, or hyphens.
for an HP Hub-16M would be
