Table 3-2 Tags for Defining Relay Options in bootptab

DescriptionTag Name

List of boot servers to which the client’s bootrequests will be forwarded. The list can contain

individual IP addresses, hostnames, or network broadcast addresses.

Client’s hardware address.

Mask for the link level address. This value is combined with the ha value to determine a match for

a group relay entry. If you specify this tag, you must also specify the ha and ht tags.

Maximum number of hops for the entry. Default is 4.

Client’s hardware type. For information on supported hardware types and the corresponding values,

type man 1M bootp at the HP-UX prompt. If used, this tag must precede the ha tag.

Specifies previously listed entry that contains tag values that are shared by several client entries.

A relay entry can contain relay parameters for an individual system or for a group of systems.

If a BOOTP client does not have an individual entry in the BOOTP server’s /etc/bootptab

file, the group relay entries are searched. The first group relay entry that matches the BOOTP

client is used.

Examples of Adding BOOTP Clients

This section shows examples of adding entries to the /etc/bootptab file. The first example

shows how to configure a BOOTP server for an HP 700/X terminal. The second example shows

how to configure a BOOTP server to relay a client’s bootrequest to another server.

Example 1: Adding an HP 700/X Terminal as a Client

Figure 3-1 shows the network configuration for this example.

Figure 3-1 Example Configuration: HP 700/X Terminal as Client

You must add the following information to the /etc/bootptab file on the BOOTP server

(hpserver):

xterm01: hn: ht=ehter: ha=080009030165: \

ip=15.19.8.37: sm=255.255.248.0: \ gw=15.19.8.1: ds=15.19.8.119: bf=/xterminal

To verify the new /etc/bootptab entry, do the following on the BOOTP server:

1. Add the ba (broadcast address) tag to the entry so that the bootreply is not sent directly to

xterm01. This allows the bootpquery diagnostic tool to intercept any bootreply packets

for xterm01.

xterm01: hn: ht=ether: ha=080009030165: \

ip=15.19.8.37: sm=255.255.248.0: \ gw=15.19.8.1: ds=15.19.8.119: bf=/xterminal: ba

2. Run the bootpquery tool to check how bootpd on your local system responds to a request

from xterm01. For the example configuration, you can enter the following (as superuser):

/usr/sbin/bootpquery 080009030165 -s hpserver
