Definitions of Managed Objects for SNA NAUs using SMIv2

RFC 1666                       SNANAU MIB                    August 1994


   This MIB module does not support:

   o    creation of links,

   o    activation or deactivation of LUs, nor

   o    activation of sessions.

3.1.  Applying MIB II to managing SNA NAUs

   This section identifies how MIB II objects, specifically the MIB II
   system group will be used in SNMP-based management of SNA NAUs.  The
   MIB II system group applies to the SNMP Agent.  The following object
   is from the MIB II system group:

   sysUpTime:  clock in the SNMP Agent/proxy-Agent; expressed in
           TimeTicks (1/100s of a seconds).

   This MIB module uses the TimeStamp TEXTUAL-CONVENTION which is
   defined in the SNMPv2 Textual Conventions (RFC 1443 [6]) as "the
   value of MIB II's sysUpTime object when a specific occurrence
   happens." The specific occurrences related to SNA NAU management are
   defined in this MIB module.

3.2.  SNANAU MIB Structure

   The SNANAU MIB module contains three groups of objects:

   o    snaNode - objects related to Node configuration, monitoring and
        control.

   o    snaLu   - objects related to LU definition, monitoring and
        control.

   o    snaMgtTools  - objects related to specific management tools well
        known in SNA environment.

   These groups are described below in more detail.

   The objects related to PUs and LUs are organized into two types of
   tables: the Admin and Oper tables.

   The "Admin" table contains parameters which are used by a Management
   Station to affect the operation of the SNA service.  Some parameters
   are used to initialize and configure the SNA service at the next
   startup, while others can take effect immediately.  A Management
   Station can dynamically define SNA resources (PUs, LUs) by creating
   new entries in the Admin table. It uses a special object, AdminState,
