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
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.
