1.0  The SNMPv2 Network Management Framework

   The SNMP Network Management Framework presently consists of three
   major components.  They are:

      RFC 1902 [2] which defines the SMI, the mechanisms used for
      describing and naming objects for the purpose of management.

      STD 17, RFC 1213 [4] defines MIB-II, the core set of managed
      objects for the Internet suite of protocols.

      STD 15, RFC 1157 [5] and RFC 1905 [6] which define two versions of
      the protocol used for network access to managed objects.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.

1.1  Object Definitions

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the subset of Abstract Syntax Notation One (ASN.1)
   defined in the SMI.  In particular, each object type is named by an
   OBJECT IDENTIFIER, an administratively assigned name.  The object
   type together with an object instance serves to uniquely identify a
   specific instantiation of the object.  For human convenience, we
   often use a textual string, termed the descriptor, to refer to the
   object type.

2.0  Overview

   This memo identifies the set of objects for configuring, monitoring,
   and controlling Data Link Switches.

2.1  Relation to Interface Group (RFC 1573) [8]

o   ifIndex is used as the index into dlswIfTable, which shows and
    controls the interfaces that DLSw is active on.

o   Local entries in the MAC address and NetBIOS (NB) name caches can
    point to an ifEntry to indicate the interface through which DLSw can
    reach that MAC address or NB name.  See the objects
    dlswDirMacLocation and dlswDirNBLocation.

o   Local entries in the circuit table use ifIndex to indicate the
    interface through which DLSw is connected to the local end station.
