HP DECnet-Plus for OpenVMS allows you to run DNA and OSI
    applications over an IP network backbone.  Applications
    include those supplied by HP, third-party applications, and
    user-written applications.

    RFC 1006 and RFC 1859 (formerly known as RFC 1006 Extension)
    are standards of the Internet community.  RFC 1006 defines
    how to implement ISO 8073 Class 0 on top of TCP.  Hosts that
    implement RFC 1006 are expected to listen on TCP port 102.

    RFC 1859 defines how to implement ISO 8073 Transport Class 2
    Non-use of Explicit Flow Control on top of TCP.  Hosts that
    implement RFC 1859 are expected to listen on TCP port 399.

    The DECnet over TCP/IP feature (RFC 1859) allows traditional
    DECnet applications (such as MAIL, CTERM, and FAL) to accept
    IP names and addresses.  The OSI applications over TCP/IP
    feature (RFC 1006) allows OSI applications (such as FTAM and
    VT) to accept IP names and addresses.

1  –  Configuring

    Methods of configuring OSI over TCP/IP and DECnet over TCP/IP
    depend upon the operating system in use.

1.1  –  Tru64 UNIX

    Running OSI applications over TCP/IP (RFC1006) is automatically
    enabled when you install and configure DECnet.  To enable DECnet
    over TCP/IP (RFC1859), you can either run "decnetsetup advanced"
    and answer "yes" to the question "Do you want to configure DECnet
    over TCP/IP?" or you can run dxdecnetsetup, select the advanced
    format, and select the "Configure DECnet over TCP/IP" option.

1.2  –  OpenVMS

    If you want to use OSI applications over TCP/IP and/or DECnet
    over TCP/IP, invoke NET$CONFIGURE with the ADVANCED option,
    and select Option 4 ("Configure Transports") to configure (or
    reconfigure) the OSI transport.  You can then create a new
    OSI transport NCL script (or replace the old script).  You
    must also include Domain in your Session Control naming search
    path by selecting Option 2 to rename your node.  This is
    described in Section 2 of the Applications Installation and
    Advanced Configuration Manual.

    For the changes to take effect, either disable the OSI
    transport entity (if it exists) and invoke the new OSI
    transport NCL script, or reboot the system.

    NCL> disable osi transport
    NCL> do sys$manager:net$osi_transport_startup.ncl

    Also, ensure that TCP/IP is started on the node and that the
    PWIP driver is loaded.

    When configuring RFC 1006, RFC 1859, or both, each element in
    the OSI transport entity's set of RFC 1006 listener ports
    attribute corresponds to a TCP listener port.  By default,
    NET$CONFIGURE sets the OSI transport RFC 1006 listener ports
    attribute to { 102, 399 }.  Port 102 is required for RFC 1006,
    and port 399 is required for RFC 1859.

2  –  Additional Template Creation (OpenVMS)

    To create RFC 1006 or RFC 1859 templates in addition to the
    default templates, use Option 4 under the NET$CONFIGURE
    ADVANCED option.  When the procedure asks if you want to
    create additional OSI templates, answer yes.  Then select
    RFC 1006 as the network service.

    The RFC 1006 port number attribute of the OSI transport
    template subentity must contain a TCP port number that is
    one of the chosen RFC 1006 or RFC 1859 listener ports.  The
    default value for the RFC 1006 port number attribute is 102.
    If you create an OSI transport template subentity to use
    with DECnet over TCP/IP (RFC 1859), then set the RFC 1006
    port number attribute of that template to 399.

3  –  Disabling (OpenVMS)

    DECnet-Plus only attempts to locate TCP/IP if the RFC 1006
    listener ports attribute set of the OSI Transport entity is
    not empty.

    To disable OSI over TCP/IP (RFC 1006) and/or DECnet over
    TCP/IP (RFC 1859), you can discontinue listening on the
    appropriate port(s).  Port 102 applies to RFC 1006, and
    Port 399 applies to RFC 1859.

    For example, this will disable both RFC 1006 and RFC 1859:

    NCL> disable osi transport
    NCL> remove osi transport rfc1006 listener ports {102,399}
    NCL> enable osi transport
