                          DECrouter 2000 V1.2 Release Notes

          This document contains information not included elsewhere in
          the DECrouter 2000 documentation. This information includes
          hints about using the DECrouter 2000, software changes and/or
          documentation changes.

          This document is intended for use with Version 1.2 of the DE-
          Crouter 2000.

          READ THESE NOTES BEFORE INSTALLING OR USING THE SOFTWARE.


          1  The DECrouter 2000 Documentation Set

          The DECrouter 2000 documentation set consists of the following:

          o  DECrouter 2000 Installation Procedures (for VAX/VMS and
             ULTRIX systems)

          o  DECrouter 2000 MS-DOS Installation Procedures

          o  DECrouter 2000 Management Guide

          o  DECrouter 2000 Problem Solving Guide

          o  DECrouter 2000 Release Notes (Online)

          o  Routing and Networking Overview

          2  New Features for V1.2

          This version of the DECrouter 2000 has the following new fea-
          tures:

          o  Support for MS-DOS and PC DOS operating systems as load hosts

          o  Support for ULTRIX systems on RISC processors as load hosts

          o  Support for using 2 lines at 384 Kbps and 3 lines at 256 Kbps
             on the DEC MicroServer (DEMSA)

                                                                         1

 






          o  If you are running the DECrouter 2000 on a DEC MicroServer-SP
             (DEMSB), note that:

             o  The supported maximum line speed is 64 Kbps. This replaces
                the previous maximum line speed of 19.2 Kbps.

             o  The 16 node limit on the number of local Ethernet connec-
                tions no longer applies. Previously, the DEMSB supported
                only 16 local Ethernet connections.

          3  Software Changes

          The following sections describe the software changes for this
          release.

          3.1  DEMSA Line Configuration

          If you are running the DECrouter 2000 on a DEMSA, the DECrouter
          2000 Version 1.2 supports the following line configurations:

               Number of lines     Maximum Speed             Ports
                                  (bits per second)
                     4                  64K               0, 1, 2, 3
                     3                 256K                 0, 1, 2
                     2                 384K                   0, 1
                     1                 2.084M                   0

          During the ROUSETUP procedure, you are prompted for details of
          the lines you want to use with the DECrouter 2000 on a DEMSA.
          The display is as follows:

               Type   Number of lines    Maximum Speed        Ports
                                       (bits per second)
                1           4                 64K           0, 1, 2, 3
                2           2                256K              0, 1
                3           1                2.084M              0

               Type [1]:

          2

 






          If you require 3 lines with a maximum speed of 256K, you must:

          1. Select Type 1 (4 lines)

          2. Only use ports 0, 1, and 2.

          If you select Type 2 (2 lines), the maximum line speed is now
          384K and not 256K.

          3.2  Changing the Executor Type

          You should not change the executor type of your DECrouter 2000
          while the system is running. If you wish to change the executor
          type, run ROUPERM in order to change the permanent database and
          reboot your system.


          3.3  Use of Service Passwords

          As the DECrouter 2000 system is on an open network - the Eth-
          ernet - it can be controlled from any node on that network.
          Service passwords give some degree of protection to a DECrouter
          2000 system. If the DECrouter 2000 does not have this protec-
          tion, any node on the same LAN could reload, dump, or trigger
          the system.
          A service password is a hexadecimal number that, if defined,
          must be specified by the user when they:

          o  Use the TRIGGER or LOAD commands from a VAX/VMS or ULTRIX
             host node

          o  Use the MOP TRIGGER command from an MS-DOS load host node

          o  Connect a terminal on a host node as a remote console

          The DECrouter 2000, as supplied, has no password defined. This
          allows you to install and configure the system. After doing
          this, you are recommended to define a password. Refer to Ap-
          pendix C in the DECrouter 2000 Problem Solving Guide for de-
          tails.

                                                                         3

 









          3.4  Using the DECrouter 2000 V1.2 over T1/G.703 Lines and
               Satellite Links

          The DECrouter 2000 V1.2 supports use of T1/G.703 high-speed
          lines and satellite links.

          To use a T1/G.703 or a satellite link with this product, you
          must:

          o  Configure your DECrouter 2000 following the procedures de-
             scribed in the DECrouter 2000 installation procedures.

          o  Check that the RECEIVE BUFFERS parameter for the line is set
             to 256.

          o  Check that the MAXIMUM TRANSMITS parameter for the circuit is
             set to 255.

          o  Fit a suitable DSU/CSU converter between the DECrouter 2000's
             RS422 or V.35 and the high-speed link.

          o  Set the clocking on the DCE.

          o  Ensure that you are using the correct length cable for the
             line interface.

          If you are using a T1/G.703 link, you must also check that the
          HIGH SPEED ENABLED parameter has been set using the ROUPERM
          program.

          If you are using a satellite link over lines with a maximum
          speed of 384Kbps or less, do NOT set the HIGH SPEED ENABLED
          parameter. The HIGH SPEED ENABLED parameter need only be set for
          lines with a maximum speed greater than 384Kbps.

          4  Documentation Changes

          The following sections describe the documentation changes for
          this release.

          4.1  Routing and Networking Overview

          There is a new version of the Routing and Networking Overview
          for this release. If you are an existing DECrouter 2000 user,
          please remove the old Routing and Networking Overview manual and
          insert the new one into your documentation binder.

          4.2  Software Version

          The covers of the DECrouter 2000 Management Guide, DECrouter
          2000 Installation Procedures for VMS and ULTRIX load hosts,
          and the DECrouter 2000 Problem Solving Guide state the software
          version as V1.1. This should be read as V1.2.

          All of the information documented in these manuals is valid for
          the DECrouter 2000 V1.2.

          4.3  Pre-Installation Information

          In the DECrouter 2000 Installation Procedures, Digital suggests
          that you complete Table 1-3 Pre-Installation Information before
          installing the product. To find the load host service circuit
          name(s), start NCP (the Network Control Program) on your load
          host and enter the following command:

               NCP> SHOW KNOWN CIRCUITS

          The display shows the load host service circuit name listed
          under Circuit. For example, QNA-0.

          The DECrouter 2000 Management Guide describes how to start NCP
          on VMS and ULTRIX load hosts.


                                                                         5

 






          4.4  Tailoring the Installation

          Section 4.2 of the DECrouter 2000 Installation Procedures in-
          cludes the sentence "Refer to Chapter 3 of the DECrouter 2000
          Installation Procedures for further details".

          This should read, "Refer to Chapter 5 of the DECrouter 2000
          Installation Procedures for further details".

          4.5  Ethernet Controller Type for VMS Load Hosts

          Page 3-6 of the DECrouter 2000 Installation Procedures lists
          DEBNT as an Ethernet controller that can be used for VMS load
          hosts.

          The DEBNT is not supported on VMS V5.0 or later. It is supported
          on VMS V4.7.

          4.6  Location of Release Notes for VMS Load Hosts

          Page C-1 of the DECrouter 2000 Installation Procedures lists the
          location of these Release Notes as SYS$COMMON:[DECSERVER]. This
          information is incorrect, as they are located in SYS$HELP.

          4.7  Installation and Configuration Procedures for ULTRIX Load
               Hosts

          The following sections give additional information on installing
          and configuring the software for ULTRIX load hosts. They should
          be read in addition to the information given in the DECrouter
          2000 Installation Procedures.








          6

 






          4.7.1  Checking Disk Space

          To check disk space on an ULTRIX load host system, enter the
          following command:

               df /usr

          From the display, check the number of free Kbytes listed in the
          Kybtes Free field.

          Table 1-1 of the DECrouter 2000 Installation Procedures shows
          how much disk space is needed to install the software.

          4.7.2  Checking mop_mom

          Section 4.1 of the DECrouter 2000 Installation Procedures in-
          structs you to check that the mop_mom process is running before
          you install the software.

          To check that the mop_mom process exists on your system, enter
          the following command:

               ls /etc/mop_mom

          If an error message is displayed, you need to install MOP
          from the DECnet-ULTRIX kit on your load host system, before
          installing the DECrouter 2000 software.

          4.7.3  Starting mop_mom

          Section 4.1 of the DECrouter 2000 Installation Procedures de-
          scribes how to start the mop_mom process. To ensure that mop_mom
          is started each time the system is rebooted, Digital recommends
          you edit the /etc/rc.local file to include the following startup
          command:

               /etc/mop_mom


                                                                         7

 






          4.7.4  Checking DECnet and NCP

          Section 5.1.1 of the DECrouter 2000 Installation Procedures
          recommends that before you run the rouconfig procedure, you
          perform the following checks:

          o  Ensure that DECnet is running on your load host node

          o  Ensure that ncp (the Network Control Program) is installed

          To check that DECnet is running and that ncp is installed, enter
          the following command:

               ncp show known circuit

          If DECnet and ncp is installed, the command displays a Known
          Circuit Volatile Summary. To ensure that DECnet is running,
          check that the display shows the State of the circuit is ON.

          If an error message is returned, DECnet-ULTRIX is either not
          installed or started. Refer to the DECnet-ULTRIX documentation
          set for more information.

          4.7.5  ULTRIX man pages

          The apropos database is not updated on installation. Therefore,
          the commands apropos and man -k will not show any information
          relating to rouperm and the DECrouter 2000. To overcome this,
          you must rebuild the file /usr/lib/whatis by entering the system
          manager command:

               catman -w

          4.8  MS-DOS Load Host Management and Problem Solving

          The DECrouter 2000 Problem Solving Guide and DECrouter 2000
          Management Guide are designed for VAX/VMS and ULTRIX users
          and do not mention MS-DOS load hosts. However, most of the
          procedures documented in these manuals can be used on an MS-DOS
          system.

          8

 






          The following procedures cannot be used on an MS-DOS system:

          o  The DECrouter 2000 Management Guide describes how to use NCP
             (the Network Control Program) to configure the DECrouter 2000
             volatile database. With an MS-DOS load host, only the NCP
             SHOW command can be used to display information about the
             DECrouter 2000. See the DECnet-DOS Network Management Guide
             for more information.

          o  The DECrouter 2000 Problem Solving Guide describes how to
             set up a VAX/VMS or ULTRIX host node as a remote console. An
             MS-DOS load host cannot be used as a remote console.

          o  The DECrouter 2000 Problem Solving Guide describes how to
             permit the load host to receive and display events generated
             by the DECrouter 2000. Personal computer load hosts cannot
             receive events from a running DECrouter 2000. Therefore,
             event logging must be directed to a VAX/VMS or ULTRIX node.





















                                                                         9
