BOOTP Service
The bootpd Configuration File
Adding Client and Relay Data to bootpd
Configuration File
To allow a client to boot from your local system or to allow a boot
request to be relayed to the appropriate boot server, you must add
information about the client to the bootpd configuration file. This file
contains client entries and relay entries. Client entries provide the
information necessary to allow clients to boot from your system. Relay
entries provide the information necessary to relay a boot request to one
or more bootpd servers.
The information that you need to collect for these types of entries is
explained in the next two sections.
Collecting Client Information
To make an entry for the client in the bootpd configuration file, you
need to collect information about the client such as the following:
• Name of the client’s system.
• Type of network interface hardware (IEEE 802.3 or Ethernet).
• Client’s hardware address.
• Client’s assigned IP address.
• IP address mask that identifies the network where the client resides.
• Address of the gateway for the client’s local subnet.
• Name of the boot file that the client will retrieve using TFTP.
Collecting Relay Information
To make a relay entry for the client in the bootpd configuration file, you
need to collect information such as the following:
• Name of the client’s system.
• Type of network interface hardware (IEEE 802.3 or Ethernet).
• Client’s hardware address.
• Subnet mask used to identify the network address where the client
resides.
• Address of the gateway that connects the client’s local subnet to the
intended BOOTP server’s subnet.
• IP addresses of the BOOTP servers to which the local system will
relay the client’s boot request.
• Threshold value, which is the number of elapsed seconds since the
client’s first request.
• Maximum number of hops that the client’s boot request can be
