2-19Remote Annex 6300 Hardware Installation Guide
Chapter 2 Installing the Remote Annex 6300
The Remote Annex 6300 supports the BOOTP and RARP protocols.
Use these protocols to obtain boot information from a UNIX host
without requiring any manual set-up on the Remote Annex 6300.
❑ BOOTP allows a diskless client to determine its IP address,
the IP address of the server, and the name of the file to be
loaded into memory.
❑ RARP maps a hardware address into an IP address.
The ROMs invoke this system of acquiring boot information when a
boot is initiated and the Remote Annex 6300 is not initialized. Under
this condition, the Remote Annex 6300 first tries to get boot
information via BOOTP or RARP.
If all requests fail, the Remote Annex 6300 will return to the ROM
monitor (if in Test mode) or continue the auto-initializing procedure
indefinately (if in Normal mode).
BOOTP
For a successful BOOTP retrieval, a bootpd must be running on a host
on the same network as the Remote Annex 6300 and must have the
appropriate information in the bootptab file. The Remote Annex
6300’s
BOOTP implementation adheres to rfc951, rfc1048, and rfc1084.
A sample bootptab file entry used to initialize the Remote Annex 6300
named terminator looks like this:
remoteannexdefault:\
:sm=255.255.255.0:gw=132.245.22.66:\
:hn:vm=auto:to=-18000:
terminator:\
:ht=1:ha=00802d004879:ip=132.245.22.226:\
