4.  Object Definitions

SNA-NAU-MIB DEFINITIONS ::= BEGIN

-- This MIB module contains objects necessary
-- for management of the following SNA devices: PU types 1.0, 2.0, 2.1
-- and LU types 0, 1, 2, 3, 4, 7.  It also contains generic objects
-- which can be used to manage LU 6.2.

-- Naming conventions in this document:
-- The following names are used in object descriptors according to
-- SNA conventions.
-- The name 'PU' or 'Node' is used to describe Node type 1.0, 2.0 or
-- 2.1.
-- The name 'LU' is used to describe Logical Unit of type 0,1,2,3,
-- 4,7 or 6.2.

        MAX-ACCESS  not-accessible
        STATUS  current
        DESCRIPTION
                "This table contains objects which describe the
                configuration parameters for an SNA Node.  Link
                specific configuration objects are contained in
                a separate MIB module (e.g., SNA DLC MIB)

                corresponding to the link type.
                The table snaNodeAdminLinkTable contains objects
                which identify the relationship between node instances
                and link instances.

                The entries (i.e., rows) in this table can be created
                by either an Agent or a Management Station.
                The Management Station can do this through setting
                the appropriate value in the snaNodeAdminRowStatus.

                The snaNodeAdminRowStatus object describes the
                status of an entry and is used to change the status
                of an entry.  The entry is deleted by an Agent based
                on the value of the snaNodeAdminRowStatus.

                The snaNodeAdminState object describes the desired
                operational state of a Node and is used to change the
                operational state of a Node.  For example, such
                information may be obtained from a configuration file.

                How an Agent or a Management Station obtains the
                initial value of each object at creation time is an
                implementation specific issue.

                For each entry in this table, there is a corresponding
                entry in the snaNodeOperTable.
                While the objects in this table describe the desired
                or configured operational values of the SNA Node, the
                actual runtime values are contained in
                snaNodeOperTable."

          SYNTAX  TimeStamp
          MAX-ACCESS  read-only
          STATUS  current
          DESCRIPTION
                  "The timestamp of the last
                  change made to any object in the snaNodeLinkOperTable,
                  including row deletions/additions.

                  This object can be used to reduce frequent
                  retrievals of the snaNodeLinkOperTable by a
                  Management Station. It is expected that a
                  Management Station will periodically poll this
                  object and compare its current value with the
                  previous one.
                  A difference indicates that some Node operational
                  information has been changed. Only then will the
                  Management Station retrieve the entire table."

snaNodeStateChangeTrap NOTIFICATION-TYPE
          OBJECTS  { snaNodeOperName,
                  snaNodeOperState }
          STATUS  current
          DESCRIPTION
                  "This trap indicates that the operational state
                  (i.e., value of the snaNodeOperState object) of a Node
                   has changed. The following variables are returned:
                    snaNodeOperName - current name of the Node,
                      with the instance identifying the Node; and,

                  The value of snaNodeOperState indicates the current
                  state after the activation attempt.
