Hello,
I'm writing to find out if anyone else out there is using the 3Com
NetBuilder II for managing their campus networks (or similar). I've
been searching through the back archives for 1994, and found mostly
information on Cisco and Wellfleet. We've had a 3Com NetBuilder II
since last spring, but have just recently been told to try to put the
thing to some use. Currently it's bridging our IP traffic (network "51"
for clarity), and routing IPX traffic (all 12 ports have a different
NetWare network number, we use the building numbers for the campus as
network numbers). We enabled IPX routing so as to keep the traffic
local to each building/port, and only go across the router when accessing
a service from another building/port (I hope, we are an old mainframe/COBOL
shop converting to a UNIX machine). We currently have 4 class C IP
addresses available to the campus, and we have 1 allocated to the
"administrative" network (51), and another currently in use by the student
and "academic" network (48). The academic network covers the whole campus,
and connects the buildings by a Kalpana switch (ie. no routing). They now
have to access another class C (since "48" has topped out), and need to
route/segment. What we'd like to do is use the NetBuilder to break the
4 class C networks apart (2 in use, 2 for future) by port. For example, have
one port/fiber run to a building for administrative data, the other for
academic data (students), and to all the administrative side to access
the academic side, but not vice versa (ie. don't allow any student's to
access the administrative network). From looking at the examples in the
NB manuals I cannot tell of this is possible. What we'd need is to
assign a network "51" number to administrative ports, and one of the other
class C addresses to the academic ports, and route. The examples were
pretty cut-n-dry in that there was usually one router, two ports, and
two networks (one on each side of the router). Ours is a star/tree
scenario with the router at the top/base of the whole thing feeding
the buildings. Since we have 28 different buildings, and 4 class C
addresses, I'd have to have repetition somewhere... just don't
understand if I can do it...
If anyone is using a 3Com, or has similar experiences setting up a
campus-type LAN (or similar business equivalent), I'd love to hear
from you, and get some real-life examples.
Thanks for any/all information,
Take care,
-Rich
