Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in TCP/IP-based internets.
   In particular, it defines objects for managing networks using Layer 2
   Tunneling Protocol (L2TP).

1.0 Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet Community.
   In particular, it describes managed objects used for managing L2TP
   devices.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.0 The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o An overall architecture, described in RFC 2571 [RFC2571].

   o Mechanisms for describing and naming objects and events for the
     purpose of management.  The first version of this Structure of
     Management Information (SMI) is called SMIv1 and described in STD
     16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
     [RFC1215].  The second version, called SMIv2, is described in STD
     58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC
     2580 [RFC2580].

   o Message protocols for transferring management information.  The
     first version of the SNMP message protocol is called SNMPv1 and
     described in STD 15, RFC 1157 [RFC1157].  A second version of the
     SNMP message protocol, which is not an Internet standards track
     protocol, is called SNMPv2c and described in RFC 1901 [RFC1901] and
     RFC 1906 [RFC1906].  The third version of the message protocol is
     called SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572
     [RFC2572] and RFC 2574 [RFC2574].

   o Protocol operations for accessing management information.  The
     first set of protocol operations and associated PDU formats is
