ONFIGURATION
Address discovery obtains the information listed in this menu either
through static entries configured in firmware by the user, or by
BOOTstrap Protocol (BOOTP) or Reverse Address Resolution Protocol
(RARP) from another source during system boot. The discovery protocol
you choose defines how much additional information you must provide.
If you choose static entries (local information), no information is
discovered; you must enter all IP addressing parameters yourself. If you
choose RARP, the communications server provides its Ethernet address
in an RARP request message. The boot server maps this address into the
corresponding IP address and returns it to the communications server in
an RARP reply message. The mapping resides in the “ethers” and
“hosts” databases, contained either in files under the /etc directory or in
Network Information Service (NIS) maps. BOOTP is similar to RARP
but can return more information.
The Address Discovery option also determines how the communications
server downloads files from the boot server. If BOOTP is used, the
filename to download is obtained from the BOOTP server. If RARP or
Local Information is used, the server attempts a TFTP download of the
file named in the Network Boot String parameter. Table 4-2 lists
Address Discovery Protocol parameter options and their meaning.
If you select a value that includes BOOTP, you must add a
corresponding entry to the bootptab file on the boot server. This file is
usually found in the /etc directory, but its location may vary depending
on your operating system and TFTP software.
