1  DEFINE
 

2  COMMUNICATION_CONTROLLER
   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

3  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.
 

3  Qualifiers
 

/DESCRIPTION

      /DESCRIPTION=text

   Optional. Default: None.

   Optional text describing the communication controller.
 

/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.
 

/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.
 

3  Examples

   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.
