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.
This memo specifies a MIB module in a manner that is both compliant to
the SNMPv2 SMI, and semantically identical to the peer SNMPv1
definitions.

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
hosts.
1.1 Change Log
This section tracks changes made to the revisions of the Internet
Drafts of this document. It will be *deleted* when the document is
published as an RFC.
3 November 1997
The following changes were made for the version of the document dated
3 November 1997. These changes were made at the request of the L2TP
working group.
(1) Removed L2TP protocol stack instancing.
(2) Tunnel and Session table now extensions of ifTable.
(3) Added IP/UDP transport tables.
(4) Several objects were removed and a number of new
objects added.
(5) Sections 1.1, 2.1, 3.0, 5.0 and 6.0 added.
(6) Module Compliance information added.
2.0 The SNMP Network Management Framework
The Internet-standard Network Management Framework consists of several
components. They are:
RFC 1902 which defines the SMI v2, the mechanisms used for
describing and naming objects for the purpose of management.
RFC 1213 defines MIB-II, the core set of managed objects for the
Internet suite of protocols.
Calhoun, Reddy, Vroman, Wheeler, Caves expires March 1998 [Page 2]
INTERNET DRAFT November 1997
RFC 1157 and RFC 1905 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.
2.1. 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 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.
3.0 Overview
The objects defined in this MIB are to be used when describing Layer
Two Tunneling Protocol (L2TP) tunnels. The L2TP protocol is defined in
[6]. This MIB consists of two groups of scalar objects and several
tables:
l2tpConfig
This group of objects contains scalar configuration parameters
defining the overall or global operational characteristics of L2TP.
l2tpStats
This group of objects contains scalar status and statistics
information describing the current state of L2TP.
l2tpTunnelConfigTable
This table contains objects that can be used to configure the
operational characteristics of a single L2TP tunnel.
l2tpTunnelStatsTable
This table contains objects that can be used to describe the
current status and statistics of a single L2TP tunnel.
l2tpSessionStatsTable
This table contains the objects that can be used to describe the
current status and statistics of a single L2TP tunneled session.
l2tpUdpConfigTable
This table contains objects that can be used to configure the
operational characteristics of the IP/UDP transport layer for L2TP.
l2tpUdpStatsTable
Calhoun, Reddy, Vroman, Wheeler, Caves expires March 1998 [Page 3]
INTERNET DRAFT November 1997
This table contains objects that can be used to describe the
current status and statistics of the IP/UDP L2TP tunnel transport.
3.1 Relationship to the Interface MIB
This MIB contains several tables which are extensions to the ifTable
MIB described in [7]. A L2TP tunnel and each of the PPP sessions
multiplexed within it are represented as separate identifiable
interface sub-layers. The tunnel and session interfaces appear in the
ifStackTable at different sub-layers depending on the functionality
the tunnel endpoint is providing for each session. At the LAC end of a
tunnel endpoint the tunnel interface appears 'above' the session
interfaces. At the LNS end of a tunnel endpoint the tunnel interface
appears 'below' the session interfaces.
Calhoun, Reddy, Vroman, Wheeler, Caves expires March 1998 [Page 4]
INTERNET DRAFT November 1997
In the example diagram below, the interface layering is shown as it
appears at the LNS. Note that the L2TP tunnel interface is at the
bottom of the interface stack when the transport layer for L2TP is
IP/UDP. This is because tunneled traffic is forwarded to its
destination based on routing policy. However L2TP over transports
other than IP/UDP may define further sub-layer interfaces below the
tunnel interface.
In both diagrams the acronym "LSIF" is used to indicate "L2TP Session
I/F".

The following example diagram illustrates the interface layering as it
might occur at the LAC. In this case the tunnel interface is at the
top of the interface stack for L2TP over IP/UDP.

Except where noted below, all objects MUST be supported from the
ifGeneralInformationGroup and ifPacketGroup. Also the objects from
these groups for L2TP tunnel interfaces MUST be supported in the
following manner.
ifTable
ifType - Tunnel and session types to be assigned.
Calhoun, Reddy, Vroman, Wheeler, Caves expires March 1998 [Page 5]
INTERNET DRAFT November 1997
ifMtu - Dependant upon the transport mechanism.
ifInOctets - Octet count of all control and payload
packets received on the tunnel interface.
ifInUcastPkts,
ifInDiscards,
ifInErrors - Apply to payload packets only.
ifOutOctets,
ifOutUcastPkts,
ifOutDiscards,
ifOutErrors - Apply to both control and payload
packets.
ifXTable
ifInMulticastPkts,
ifInBroadcastPkts,
ifOutMulticastPkts,
ifOutBroadcastPkts - Are not supported. An appropriate
SNMP error MUST be returned.
The ifFixedLengthGroup, ifHCFixedLengthGroup or the ifRcvAddressGroup
are not relevant to L2TP tunnel or session interfaces.
