BOOTP Table File Entries
An entry in the BOOTP table file /etc/bootptab for an HP
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 |
| 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 |
| Ethernet). This tag must precede the ha tag. |
ha | is the “hardware address” tag. Use the hub’s |
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.
