IPX UPGRADE FOR NETWARE SERVERS 1.0a README FILE

This README file contains key information about the IPX (TM) Upgrade for 
NetWare (R) Servers 1.0a software that is not available elsewhere. This 
file covers the following topics:

- Product Overview  
- Product Interoperability
- Product Restrictions 
- Incompatibility with Other Products
- Product Configuration

Because this product contains fixes for the IPX Upgrade for NetWare 
Servers 1.0 software, this README file does not contain the installation 
instructions for this software. The installation and configuration 
instructions are provided in the IPX Upgrade for NetWare Servers 1.0 
Installation and Configuration Guide, which is included with this update 
package.


PRODUCT OVERVIEW 

IPX Upgrade for NetWare Servers 1.0a runs on NetWare 3.11, NetWare 3.12, 
NetWare 4.01, and NetWare 4.02, and includes both RIP/SAP and NetWare 
Link Services Protocol (TM) (NLSP (TM)) support. You can run NLSP on any 
IPX (Internetwork Packet Exchange (TM)) network: NetWare clients, servers, 
and third-party IPX routers all interoperate with Novell (R) NLSP routers.

The routing capabilities of IPX have been enhanced to meet a number of
customer requirements.  This software upgrades any NetWare 3 (TM) server, 
NetWare 4.01 server, or NetWare 4.02 server to the latest IPX router, 
except for systems running NetWare MultiProtocol Router (TM) 2.x software 
or NetWare 3 SFT III (TM) software.  

Features new to the IPX Upgrade for NetWare Servers 1.0a software include
the following:
 
- Ability to bind multiple NICs to a single network number and load sharing,
  particularly useful when connecting two or more interfaces on a file server
  to an Ethernet switch.
 
- SNMP instrumentation for IPX, RIP/SAP, and NLSP, along with an IPX console,
  IPXCON.NLM.  In addition, ASN.1 copies of the MIBs are included for 
  integration into SNMP management consoles.

- NetWare Link Services Protocol software, a new link state routing 
  protocol for IPX that greatly reduces routing overhead and provides more 
  diagnostics on the operation of IPX and IPX routing.

- IPXPING.NLM, a utility that tests connectivity between systems running
  IPXRTR.

- Use of the NetWare 3.12 and NetWare 4 (TM) hashing algorithm for RIP/SAP 
  processing, a method that greatly reduces CPU utilization on NetWare 3.11 
  in large IPX RIP networks.
 
- Ability to turn off routing on servers with multiple NICs.
 
- Filtering of NetBIOS packets, enabled by a SET command.

This release of IPXRTR corrects a problem with load balancing. If you
want to use load balancing, the Maximum Number of Path Splits parameter 
must be set to a value greater than 1 and less than 9. Use a text editor 
to add the following line to the GLOBAL section of the SYS:\ETC\NLSP.CFG 
file:

   MaxPaths = <value>;
  
A new SET command has been added for additional configuration of load 
balancing when a server has multiple binds to the same LAN without 
going through a router. The syntax of the new SET command is:

   SET LOAD BALANCE LOCAL LAN = <OFF/ON>

This SET command should be used in two instances. Turn on load
balancing if a server is connected to a LAN on multiple interfaces
and the interfaces are either on the same media or attached to
different ports of a switch.  Turn off load balancing if a server has
multiple interfaces to two segments of the same LAN that is also
bridged. The default value is off.

The values of 0, -1, and -2 should never be used as IPX network
numbers. These values are reserved.

PRODUCT INTEROPERABILITY

Every effort has been made to identify Novell and third-party products 
that require RIP or SAP to operate. Other Novell or third-party products 
that have not yet been identified might also require RIP or SAP. If you 
have a product that loses connectivity through a Novell NLSP server, 
complete the following steps:

1. Unload IPXRTRNM and IPXRTR by issuing the following 
   commands from the server command line:

   UNLOAD IPXRTRNM <Enter>

   UNLOAD IPXRTR <Enter>

2. Reload IPXRTR in RIP/SAP-only mode and IPXRTRNM by 
   issuing the following commands from the server command 
   line, which will return the IPX router to the default RIP/SAP-
   only mode: 

   LOAD IPXRTR <Enter>

   LOAD IPXRTRNM <Enter>

3. Check whether connectivity returns to the product.

   If connectivity returns, then the product requires RIP or SAP to 
   function. Contact Novell Technical Support at 1-800-NETWARE 
   (1-800-638-9273) if you discover any such products. 


PRODUCT RESTRICTIONS 

IPX Upgrade for NetWare Servers 1.0a is provided with the following 
restrictions:

- IPX Upgrade for NetWare Servers 1.0a does not provide support for 
  NetWare MultiProtocol Router 2.x software. Do not install IPX Upgrade 
  for NetWare Servers 1.0a on a server or router running NetWare 
  MultiProtocol Router 2.x, NetWare WAN Links (TM) 2.0, or NetWare 
  MultiProtocol Router Plus 2.x.

- This software does not provide support for systems running NetWare 3
  SFT III systems. A revision to SFT III supporting NLSP is available 
  in NetWare 4.1.

- SERVMAN configurations for IPX RIP/SAP and SAP filtering do 
  not take effect with this product.

- Before installing IPX Upgrade for NetWare Servers 1.0a on a 
  NetWare 4.01 server, you must install patch UPD296 to upgrade
  DS.NLM, your NetWare Directory Services (TM) (NDS (TM)) NLM (TM) file. 
  This update is included in the DISK1\SERVER.401 directory when IPXRTR 
  is unzipped. The disk also includes an ASCII file, UPD296.TXT, which 
  includes installation instructions. 

  Without this patch, NDS can spuriously call the "router down" 
  event. If the NLSP router goes down, the following message 
  appears on the system console:

  IPXRTR: IPX link state router down. 

  If this message appears, restart the server. This error can occur 
  when you use NetWare 3.11 or NetWare 3.12 utilities to manage the 
  bindery on the NetWare 4.01 server. It can also occur when you
  install other products on the server.

- IPXRTR.NLM fails to load if IRWASM.NLM is already loaded. If 
  you intend to run IPXRTR.NLM on the same system as NetWare 
  SNA Links (TM) 1.0 software, ensure that the LOAD IPXRTR command 
  line precedes the LOAD IRWASM command line in your AUTOEXEC.NCF file. 


INCOMPATIBILITY WITH OTHER PRODUCTS 

In certain configurations, the Intel* EtherExpress* TPE ISA hub driver 
1.12 incorrectly identifies its MAC address to the NetWare server. 
Other NLSP systems on the LAN notice the error and display the 
following message:

    A mismatched source node/data-link address *address*/
    *address* in hello packet on circuit <circuit name> from 
    <system name>.

This error causes connectivity loss and occurs when you have loaded 
two master hub boards on a single NetWare server. To prevent the 
problem, load only one master hub board per NetWare server. Simply 
unbinding IPX from the board is not sufficient. If more than one hub 
driver is loaded, the problem persists.


PRODUCT CONFIGURATION

To simplify adding the LOAD commands to your AUTOEXEC.NCF file, the 
installation process inserts the appropriate lines into the file and 
comments them out. To cause the commands to be executed each time the 
system is restarted, select the commented lines you want to run and 
remove the comment characters. 

The LOAD line options are documented in the IPX Upgrade for NetWare 
Servers 1.0 Installation and Configuration Guide. 


LOADING SNMP

When you load SNMP provided with the IPX Upgrade for NetWare 
Servers 1.0a software on a NetWare 3.11 server, the following messages 
are displayed on the console:

    SNMP: Could not register the SNMP NCP extension ID. 

    SNMP: Agent will not be able to handle SNMP over NCP 
    traffic. 

Ignore these messages. 


PRODUCT MIBs

IPX Upgrade for NetWare Servers 1.0a includes three new product MIBs that
you can integrate with Novell and third-party network management software.
These ASN.1 text files are included on Disk 1 in the REFMIBS directory if you 
have made floppies; otherwise, they are located in the DISK1\REFMIBS 
directory. Refer to the documentation for these products for information 
about installing additional MIBs.  


CREATING THE INSTALLATION DISKETTES

The IPX Upgrade for NetWare Servers 1.0 Installation and Configuration
Guide provides instructions for installing this software. Use the following
procedure to create the installation diskettes:  

1. When IPXRTR.EXE was unzipped, it created a batch file (MAKE_IPX.BAT) and 
   the following three directories: 

   - IPXSERV1 
   - IPXSERV2 
   - DISK1 

   If you want to install the software from your hard drive, proceed to 
   Step 4. 

2. If you want to install the software from diskettes, use the DOS FORMAT 
   command to format two high-density diskettes (3.5-inch or 5.25-inch).  

   The FORMAT command asks you for the label to give the diskette
   (not the label you paste on the diskette). Because the MAKE_IPX.BAT file 
   will relabel the diskettes, the labels used when formatting the diskettes 
   are unimportant.


3. If you want to install the software from diskettes, use the following 
   command to run the batch file and create diskettes on the A: drive:

      MAKE_IPX A:
   
4. If you have a NetWare 4.01 server, complete the following substeps. 
   If you do not have a NetWare 4.01 server, continue with Step 5.
 
   A. Access UPD296.EXE in the DISK1\SERVER.401 directory.
 
   B. Copy the UPD296.EXE file to the same directory as the SERVER.EXE
      and type
 
      UPD296 <Enter>
 
      This removes the old version of NetWare Directory Services
      from SERVER.EXE and inserts the new version in its place.
 
   C. UPD296 copies the original SERVER.EXE to SERVER.OLD and then
      patches SERVER.EXE. To revert to the original version of NetWare
      Directory Services, rename SERVER.OLD to a .EXE extension and
      then execute that program.
 
   D. Copy the updated SERVER.EXE to all file servers in the NDS tree.
      (This is possible because Novell licensing is no longer handled
      through SERVER.EXE.)
 
5. Follow the instructions in the PostScript* manuals you printed (described
   in the README found in IPXDOC.EXE). 

   To install the software directory from the server's hard drive, change 
   the path to <VOLUME>:<DIRECTORY>\IPXSERV1 in place of the step that 
   tells you to insert the IPX Upgrade for NetWare Servers Disk 1 into 
   the disk dive.

NOTE: If you receive the message, "IPXRTR: IPX link state router down"
on the system console, verify that Step 4 was done correctly.
