2 Introduction
This document describes a model for managing pseudo wire services
for transmission over a packet Switched Network (PSN). This MIB
module is generic and common to all types of PSN.
This document is closely related to [FRMWK], describing the
transport and encapsulation of L1 and L2 services over any type of
PSN and MPLS respectively, creating a Pseudo Wire (PW) service.
This document describes the MIB objects that define the generic
pseudo wire association to the PSN and pseudo wire configurations
that are not specific to the carried service. A PW type field will
be used to point to the relevant service MIB tables, described in
other documents. Such document is available currently for CEP
services [CEPMIB]. A similar PSN type field will point to PSN
specific modules, for example [PWMPLSMIB].

3 Terminology
This document uses terminology from the document describing the PW
framework [FRMWK].
"Adaptation" refers to the method of adapting a "foreign"
communications protocol such that it can be carried by a packet
switched net (the PSN). For example, in a CEP service the foreign
protocol is SONET/SDH and the PSN is MPLS.
"PSN Tunnel" is a general term indicating a virtual connection
between the two PW edge devices. In practice, it is not limited to
path oriented types of PSNs like MPLS; an example is IP PSN.
Since a PW service is bi-directional, a PW service requires two
uni-directional tunnels from a uni-directional oriented PSN (MPLS
for example).
4 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
described in STD 15, RFC 1157 [RFC1157]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[RFC1905].
o A set of fundamental applications described in RFC 2573 [RFC2573]
and the view-based access control mechanism described in RFC 2575
[RFC2575].

Information Base
A more detailed introduction to the current SNMP Management
Framework can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. Objects in the MIB
are defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of
machine readable information is not considered to change the
semantics of the MIB.
4.1 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, an OBJECT IDENTIFIER, an
administratively assigned name, names each object type. 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 also refer to
the object type.
5 Feature Checklist
The PW MIB (PW-MIB) is designed to satisfy the following
requirements and constraints:
- The MIB is designed to be extensible to all types of PSNs. PSNs
specific MIBs will be defined in additional documents.
- The MIB supports manually configured VCs.
- The MIB supports the VC ID and Group ID.
- The MIB supports point-to-point PW connections. Point-to-
multipoint connections are for future study.
- The MIB enables the use of any emulated service. Emulated
service specific MIBs will be defined in additional documents.
- The MIB enables both strict and loose incoming VC lookup. In
strict mode, only VC carried inside explicitly configured or
signaled tunnels are accepted in path oriented PSNs. In no path
oriented PSNs, the source address of the received packet must be
checked in strict mode.

6 PW-MIB usage
The MIB structure for defining a PW service is composed from three
types of modules.
The first type is the PW-MIB module, which configures general
parameters of the VC that are common to all types of emulated
services and PSNs.
The second type of modules is per PSN module. There is a different
module for each type of PSN. These modules associate the VC with
one or more "tunnels" that carry the service over the PSN. These
modules are defined in other documents; see for example
[PWMPLSMIB].
The third type of modules is service-specific module, which is
emulated signal type dependent. These modules are defined in other
documents; see for example [CEPMIB].
[PWTC] defines some of the object types used in these modules.
6.1 PW-MIB usage
- The VC table (pwVcTable) is used for all VC types (ATM, FR,
Ethernet, SONET, etc.). This table contains high level generic
parameters related to the VC creation. A row is created by the
operator for each PW service.
- Based on the PSN type defined for the VC, rows are created in
PSN specific module(for example [PWMPLSMIB]) and associated to the
VC table by the common VC index.
- Based on the VC type defined for the VC, rows are created in
service-specific module (for example [CEPMIB]) and associated to
the VC table by the common VC index.
- The MIB includes performance parameters collection common to all
types of PW.
6.2 Relations to the ifTable
The PW VC itself is not an ifIndex as it's own, however in many
cases the VC is associated via the MIB tables to an ifIndex the VC
is emulating. This ifIndex may represent a physical entity - for
example a PW emulating a SONET path as in CEP. The VC itself is not
an ifIndex, however the MIB associate the VC to the ifIndex of the
path to be emulated. In some cases, the VC will be associated to an
ifIndex representing a virtual interface. An examples is VPLS
service where the PW emulates a logical interface of a (logical)
bridge. The physical ports association to the VPLS service instance
is defined in non-PW MIBs in this case.
Zelig et al Expires March 2002 [page 5]
Pseudo Wire (PW) Management February 2002
Information Base
Note that the ifIndex that carry the VC toward the PSN is in
general not explicitly configured via PW MIB modules except in rare
cases. In most cases the VC is carried inside a PSN tunnel, and the
interfaces carrying the tunnel are specified in the related MIBs
that control the PSN tunnels.
6.3 Example of MIB usage
In this section we provide an example of using the MIB objects
described in section 8 to set up a CEP VC over MPLS PSN. While this
example is not meant to illustrate every permutation of the MIB, it
is intended as an aid to understanding some of the key concepts. It
is meant to be read after going through the MIB itself.
In this example a PW service for CEP is configured over an MPLS PSN
(MPLS-TE tunnel). It uses LDP as in [TRANS] for service set-up.
In PW-MIB:
In pwVcTable:
{
pwVcIndex 5,
pwVcType CEP,
pwVcOwner signaling,
pwVcPsnType mpls,
pwVcPriority 0,
pwVcInboundMode loose,
pwVcPeerAddrType ipv4,
pwVcPeerAddr 1.4.3.2, -- In this case equal to the
-- peer LDP entity IP addr
pwVcID 10,
pwVcLocalGroupID 12,
pwVcControlWord false, -- Control word not to be sent
pwVcLocalIfMtu 0, -- Do not send ifMtu parameter
pwVcLocalIfString false, -- Do not signal if string
pwVcRemoteGroupID 0xFFFF, -- Will be received by
-- maintenance protocol
pwVcRemoteControlWord notKnownYet,
pwVcRemoteIfMtu 0,
pwVcRemoteIfString "",
pwVcOutboundVcLabel 0xFFFF, -- Will be received by
-- maintenance protocol
pwVcInboundVcLabel 0xFFFF, -- Will be set by signaling
pwVcName "Example of CEP VC",

pwVcDescr "",

pwVcAdminStatus up,

}
The agent now create a row in pwVcMplsTable [PWMPLS] based on the
VcIndex, that is configured with MPLS specific values:
In pwVcMplsTable:
{
pwVcMplsMplsType mplsTe,
pwVcMplsExpBitsMode outerTunnel,
pwVcMplsExpBits 0,
pwVcMplsTtl 2,
...
}
The operator now associates the VC with an outgoing TE tunnel:
In pwVcMplsOutboundTable:
{
pwVcMplsOutboundIndex 0, -- The first row
-- for this VcIndex
pwVcMplsOutBoundLsrXcIndex 0, -- MPLS-TE
pwVcMplsOutboundTunnelIndex 500,
pwVcMplsOutboundTunnelInstance 0,
pwVcMplsOutboundTunnelLclLSR 1.2.3.4, -- Always
-- the LSR ID of the current node.
pwVcMplsOutboundTunnelPeerLSR 1.4.3.2
pwVcMplsOutboundIfIndex 0, -- MPLS-TE
..
}
pwVcMplsInboundTable is not used because loose LDP set-up is used.
pwVcMplsMappingTable entry will be created by the agent once the
LDP control session will be finished and will enable easy lookup
for the VcIndex from knowledge of VC label or tunnel.

8 Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
No managed objects in this MIB contain sensitive information.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is
no control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the
use of the User-based Security Model RFC 2574 [RFC2574] and the
View-based Access Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
