HP-UX IP Address and Client Management Administrator's Guide HP-UX 11i v2, HP-UX 11i v3

Collecting Client Information
To insert an entry for the client in the /etc/bootptab file, you need to collect the following
information about the client:
• Host name — the name of the client’s system.
• Hardware type — the type of network interface.
• Link level address — the client’s hardware address.
• IP address — the client’s assigned Internet address.
• Subnet mask — the mask (IP address) that identifies the network where the client resides.
• Gateway address — the gateway from the client’s local subnet.
• Boot file — the name of the file that the client retrieves using tftp.
Collecting Relay Information
To make a relay entry for the client in the /etc/bootptab file, you need to collect the following
information about the client:
• Host name — the name of the client’s system.
• Hardware type — the type of network interface (IEEE 802.3 or Ethernet).
• Link level address — the client’s hardware address.
• Subnet mask — the mask that is used to identify the network address where the client resides.
• Gateway address — the address of the gateway that connects the client’s local subnet to the
BOOTP server’s subnet.
• Boot servers for client — the boot servers to which the local system relays the client’s
bootrequest.
• Threshold value — the number of seconds since the client sent its first request.
• Maximum hops — the maximum number of hops that the client’s bootrequest can be
forwarded.
Understanding Boot File Configurations
A configuration entry is a single line in the following format:
hostname:tag=value:tag=value:...tag=value
Each client parameter is defined with a two-character case-sensitive tag followed by the equals
sign (=) and the tag’s client-specific value. A colon separates each tag=value parameter
definition. bootpd uses these tags and values to recognize a client’s bootrequest, supply
parameters in the bootreply to the client, or relay the bootrequest.
For example, parameters for the BOOTP client xterm01 are represented with the following entry
in the /etc/bootptab file:
xterm01: ht=ether: ha=080009030166: ip=15.19.8.2:\
sm=255.255.248.0: gw=15.19.8.1: bf=/xterm01
This entry gives bootpd the following information about xterm01:
• Hardware type is an Ethernet network interface.
• Hardware address is 080009030166.
• IP address is 15.19.8.2.
• Subnet mask is 255.255.248.0.
• The address of the gateway is 15.19.8.1.
• The file /xterm01 must be retrieved with TFTP.
