The Node module has one entity, the global node entity, which crowns the
   hierarchy represented in the entity model described by the Digital Network
   Architecture. All other entities are subordinate to the Node entity. When
   enabled, each node is visible to all other nodes on the network. Access to
   a node's entities must be made through the node.

   The following shows the hierarchical relationship of the Node global entity
   to all of the other local entities.

                             Node
                              Event Dispatcher
                              Alias
                              Session Control
                              NSP Transport
                              OSI Transport
                              Routing
                              MOP
                              CSMA-CD
                              FDDI
                              DDCMP
                              HDLC

   The node entity is the only entity in the Node module.

1  –  character

     IMPLEMENTATION

         Particular DECnet implementation of the node. You cannot modify this
         characteristic.

     VERSION

         Version number of the network management architecture specification to
         which the implementation conforms.  You cannot modify this
         characteristic.

     MAXIMUM LISTENERS ( OSF/1 only)

          Maximum number of CMIP listeners that the node supports.  Zero
          specifies an unlimited number of listeners.  You cannot modify this
          characteristic.  The characteristic has no meaning on OPEN VMS

     LISTENER_TEMPLATE ( OSF/1 only)

          Name of the OSI transport template to be passed through the CMIP
          listener to session control.  You cannot modify this characteristic.

     SECONDARY NAMES

          Lists the set of secondary fullnames the node might have due to more
          than one nameservice.

2  –  counters

     CHANGES OF ADDRESS

         Number of times the node's address has changed.

     CHANGES OF ID

         Number of times the node's ID has changed.

     IDROM CHECK FAILURES

         Number of times an IDROM was checked for consistency and was found to
         be in error.

     RENAMES

         Number of times the node has been renamed.  See the rename command.

3  –  status

     FUNCTIONS ENABLED

         Functions that are currently enabled for the node.  See the enable
         command.

     ID

         Indicates the unique 48-bit ID of the node.

     STATE

         State of the node.

         BOOTING - The node is attempting to downline load. You cannot manage
                   the node in this state. If the boot process is successful,
                   the node enters the off state. This function is only
                   supported on OpenVMS.

         DEAD -    The node is unusable and unmanageable as the result of a
                   power failure or similar event. The node must be rebooted.
                   This function is only supported on OpenVMS.

         OFF -     The node is manageable, but not all of its functions are
                   enabled.

         ON -      All of the node's functions are enabled, and the node is
                   fully manageable. The on state is the normal operating state.
