ABSTRACT: PSF/6000 : Valid configurations for supporting
TCP/IP ethernet 3900's

Customer is planning to install TCP/IP 3900 driven by PSF/6000. Print
data will be sent to the PSF/6000 server from multiple HP/UX machines.
The HP machines the PSF/6000 server and the 3900 will all be connected
via a PlainTree intelligent ethernet switching hub. My understanding of
this hub is that it is capable of providing a full 10 MB pathway between
any two devices.
After reading the announce letters for PSF/6000 and 3900 TCP/IP my
client has the following questions:
1) Will the PSF/6000 and the 3900 TCP/IP connection work with the
proposed intelligent hub? Will it work with any intelligent hub?
2) Will any make of TCP/IP software that supports LPR/LPD work for the
transfer of the print stream from the HP to the PSF server or must
the TCP/IP software be an IBM product? The client seems particularly
concerned about support for IP stacks (of which I am completely
unfamiliar) - are there network software issues we need to understand
or will any flavor of TCP/IP and any hub hardware work? For the
record, the announce letters lead us to believe that different makes
of hub hardware and software will work successfully as long as we
build a valid ethernet network - is this right?
A:
We have not done any official testing of PSF/6000 or the 3900 TCP/IP
attachment with hub hardware. We followed industry standards in the
design for the 3900 TCP/IP Ethernet attachment, so if PlainTree did as
well, then it should work. As far as PSF/6000 goes, it has nothing to
do with communications at all; it just sits as a backend to the normal
AIX spool. AIX implemented their remote printing capability (LPR/LPD)
following the industry standard RFC 1179, so I believe you should be
okay there as well.
We do have customers printing today from HP9000s running HP/UX to
PSF/6000-attached printers, including 3900-OW1s that are Ethernet-
attached without problems. I can give you the IBM contact for one
account if you'd like a reference. I do not know if that customer's
network uses hubs or not. (The enhanced LPR sample code that we supply
for OEM UNIX systems has been tested successfully on an HP/UX system,
so not only can you print, with this sample C code compiled there, your
customer will have the capability of passing parameters to PSF/6000
if they so desire.)
