2101.0. "DECswitch/IPX config questions..." by ANGLIN::BERNDT () Tue Mar 14 1995 11:41

    We are configuring a large FDDI/Ethernet network for a "major airport"
    in the Chicago area... We are competing against Cisco and have some
    specific questions about the DECswitch 900EF in a Novell Netware
    environment:
     
    1.  The support of Novell Netware 4.1.  The preferred packet format is
    the Netware 802.2 version.  I have provided an excerpt out of the
    recent Network Buyers Guide that shows 802.2 and 802.3 format support.
    Does this include Novell?  What is the setup at the client (on
    ethernet) and the server (on FDDI) when Netware 802.2 format support
    is required? 
     
    2. Future migration is planned away from the IPX protocol to TCP/IP.
    I have yet to determine if the customer is on the Internet, I suspect
    not.  There are only three server location planned with an increase in
    client population toward 1000 Netware clients.  As this network will
    be composed of translation bridges and is highly controlled, is there
    any downside to this approach?  We have discussed addressing for TCP.
    This seems to be the proper selection of the subnet mask to 
    allow the proper number of clients and the extent of support by
    Netware. 
     
    I need to wrap these issues up quickly as this is a fast track project
    that is expected to fly through the approval process... 
    
    Thanks in advance for any/all responses... ITASCA::BERNDT  DTN:446-2514

	Using 802.2 format, you need configure nothing on the DECswitches to make IPX work. It's only when using the 802.3 format, also referred to as "Raw 802.3 IPX", that you need to flip a switch on all DECswitches called the Raw IPX switch. Of the 3 Novell formats, it is the only one that has caused problems for customers, and should be stayed away from. I'm having trouble understanding your other question. You mention a move away from IPX to TCP/IP, then mention translational bridging, and then ask whether this is the proper subnet mask. If the question is, is it OK to use bridges with IP rather than routers, the answer is yes as long as there aren't too many end stations. 1000 stations in multiple subnets would probably require at least a couple routers to operate stably.
