Defines the mapping between a communication controller device and
    its corresponding Internet interface. Each mapping or controller
    definition is stored as a record in the configuration database.

    To modify an existing controller definition, you must delete the
    old controller definition from the configuration database (using
    the DELETE COMMUNICATION_CONTROLLER command) and then define
    the new controller definition (using the DEFINE COMMUNICATION_
    CONTROLLER command).

    Internet devices are uniquely identified using 2-character names.
    The first character is determined by the /INTERNET_INTERFACE
    qualifier. The second character is determined by the controller
    type you specify with the /TYPE qualifier, as follows:

    Controller
    Type             Second Character of Interface Name

    ETHERNET         E
    FDDI             F
    PPP              P
    SERIAL           L
    TOKEN_RING       T

    For example, with the following command, the communication
    controller EW maps to the interface WE:

    TCPIP> DEFINE COMMUNICATION_CONTROLLER EW -
    _TCPIP> /INTERNET_INTERFACE=W /TYPE=ETHERNET

    Related commands: LIST COMMUNICATION_CONTROLLER,
    DELETE COMMUNICATION_CONTROLLER, all INTERFACE commands

1  –  Parameters

 controller

    Required.

    Specifies the OpenVMS device name of the communication controller
    (as displayed by the DCL command SHOW DEVICE) to be mapped to an
    Internet interface. For examples of communication controllers
    with their corresponding Internet interfaces, refer to the
    LIST COMMUNICATION_CONTROLLER command. For more information on
    configuring network interfaces, refer to the HP TCP/IP Services
    for OpenVMS Management manual.

2  –  Qualifiers

2.1    /DESCRIPTION

       /DESCRIPTION=text

    Optional. Default: None.

    Optional text describing the communication controller.

2.2    /INTERNET_INTERFACE

       /INTERNET_INTERFACE=character

    Required.

    Specifies the first character of the Internet interface name.
    If you prefer using a standard name, call your HP support
    representative.

2.3    /TYPE

       /TYPE=(option[,...])

    Required.

    Specifies the communication controller type and cluster
    attribute. You must specify one of the following communication
    controller types: ETHERNET, FDDI, PPP, SERIAL, or TOKEN_RING.

    Optionally, specify the CLUSTER attribute to indicate that the
    interface can join an Internet cluster. To enable a cluster alias
    (alias host identifier) with an interface, use the SET INTERFACE
    /CLUSTER command.

    1.TCPIP> DEFINE COMMUNICATION_CONTROLLER ES -
      _TCPIP> /INTERNET_INTERFACE=S /TYPE=(ETHERNET,CLUSTER) -
      _TCPIP> /DESCRIPTION="DESVA-Class Ethernet Adapter"

      Defines the OpenVMS device ES as the Internet interface SE,
      which can join an Internet cluster.
