1 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 defines a MIB module that can be
used to manage pseudo wire (PW) services for transmission over a
packet Switched Network (PSN) [RFC3931][RFC4447]. This MIB module
provides generic management of PWs which is common to all types of
PSN and PW services defined by the IETF PWE3 Working Group.
Comments should be made directly to the PWE3 mailing list at
pwe3@ietf.org.

2 Terminology
This document adopts the definitions, acronyms and mechanisms
described in [RFC3985] and [RFC3916]. Unless otherwise stated, the
mechanisms of [RFC3985] apply and will not be re-described here.
3 The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7
of RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. MIB objects are
generally accessed through the Simple Network Management Protocol
(SNMP). Objects in the MIB are defined using the mechanisms
defined in the Structure of Management Information (SMI). This
memo specifies a MIB module that is compliant to the SMIv2, which
is described in STD 58,RFC 2578 [RFC2578], STD 58, RFC 2579
[RFC2579] and STD 58, RFC 2580 [RFC2580].
4 PWE3 MIB modules Architecture
The MIB structure for defining a PW service is composed from three
types of MIB modules.
The first type is the PW-STD-MIB module, which configures general
parameters of the PW that are common to all types of emulated
services and PSN types.
The second type of modules is PSN type specific module. There is a
different module for each type of PSN. These modules associate the
PW with one or more "tunnels" that carry the service over the PSN.
These modules are defined in other documents.
The third type of modules is service-specific module, which is
emulated signal type dependent. These modules are defined in other
documents.
[PWTC] defines some of the object types used in these modules.
Zelig et al Expires December 2006 [page 3]
Pseudo Wire (PW) Management June 2006
Information Base
4.1 PW-STD-MIB module usage
An entry in the PW table (pwTable) MUST exist for all PW types
(ATM, FR, Ethernet, SONET, etc.). This table holds generic
parameters related to the PW creation and monitoring.
A conceptual row can be created in the pwTable in one of the
following ways:
1) The operator creates a row in the PwTable when configuring the
node for a new service. This mode MUST be supported by the agent,
and MUST be used when creating a non-signaled PW (manually
assigned).
2) The agent MAY create a row in the PwTable if a signaling
message has been received from a peer node for a combination of
signaling identifications parameters already unknown to the local
node. This mode is OTIONAL.
3) The agent MAY create a row in the PwTable automatically due to
some auto discovery application, or based on configuration that is
done through non-SNMP applications. This mode is OPTIONAL.
- The agent than creates the rows in the (locally supported)
performance tables and reverse mapping tables in PW-STD-MIB
module.
4.2 Relations to other PWE3 MIB modules
- Based on the PSN type defined for the PW, rows are created in
PSN specific module (for example [PWMPLSMIB]) and associated to
the PW table by the common pwIndex.
- Based on the PW type defined for the PW, rows are created in
service-specific module (for example [CEPMIB]) and associated to
the PW table by the common pwIndex.
- Unless all the necessary entries in the applicable tables have
been created and all the parameters have been consistently
configured in those tables, signaling cannot be performed from the
local node, and the pwVcOperStatus should report 'notPresent'.
5 Relations to the ifTable
The PW itself is in general not an ifIndex as it's own, from agent
scalability reasons. The PW is typically associated via the PWE3
MIB modules to an ifIndex the PW is emulating. This ifIndex may
represent a physical entity - for example a PW emulating a SONET
path as in CEP: The PW itself is not an ifIndex, however the PW-
STD-CEP-MIB module associates the PW to the ifIndex of the path to
Zelig et al Expires December 2006 [page 4]
Pseudo Wire (PW) Management June 2006
Information Base
be emulated. In some cases, the PW will be associated to an
ifIndex representing a virtual interface. An example 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.
Exception to the above MAY exist in some implementations, where it
is convenient to manage the PW as an ifIndex in the ifTable. A
special ifType to represent a PW virtual interface (exact number
to be assigned by IANA) will be used in the ifTable in this case.
Note that the ifIndex that carry the PW toward/from the PSN is in
general not explicitly configured via PWE3 MIB modules except in
rare cases. In most cases the PW is carried inside a PSN tunnel,
and the interfaces carrying the tunnel are specified in the
related MIBs that control the PSN tunnels.
6 Example of the PW MIB modules usage
In this section we provide an example of using the MIB objects
described in section 7 to set up a CEP PW 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 [RFC4447] for service set-
up.
In the PW-STD-MIB module:
In pwTable:
{
pwIndex 5,
pwType cep,
pwOwner pwIdFecSignaling,
pwPsnType mpls,
pwSetUpPriority 0, -- Highest
pwHoldingPriority 0, -- Highest
pwInboundMode loose,
pwPeerAddrType ipv4,
pwPeerAddr 1.4.3.2, -- In this case equal to the
-- peer LDP entity IP addr
pwID 10,
pwLocalGroupID 12,
..
pwCwPreference true, -- Actually ignored for CEP
pwLocalIfMtu 0, -- Do not send ifMtu parameter
Zelig et al Expires December 2006 [page 5]
Pseudo Wire (PW) Management June 2006
Information Base
pwLocalIfString false, -- Do not send interface string
pwCapabAdvert 0, -- Does not support status
-- report to the peer.
pwRemoteGroupID 0xFFFF, -- Will be received by
-- signaling protocol
pwRemoteCwStatus notKnownYet,
pwRemoteIfMtu 0,
pwRemoteIfString "",
pwRemoteCapabilities notYetKnown,
..
pwOutboundVcLabel 0xFFFF, -- Will be received by
-- signaling protocol
pwInboundVcLabel 0xFFFF, -- Will be set by signaling
-- protocol
pwName "Example of CEP PW",
pwDescr "",
..
pwAdminStatus up,
..
}
For the operation in the service specific MIB modules and the PSN
specific MIB modules, see the specific MIB module memo. This
example is continued in the memo describing the PW-CEP-STD-MIB
module [CEPMIB] and the PW-MPLS-STD-MIB module [PWMPLSMIB].

9 Security considerations
It is clear that this MIB module is potentially useful for
monitoring of PW capable PEs. This MIB module can also be used
for configuration of certain objects, and anything that can be
Zelig et al Expires December 2006 [page 50]
Pseudo Wire (PW) Management June 2006
Information Base
configured can be incorrectly configured, with potentially
disastrous results.
There are number of management objects defined in this MIB module
with 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. These are the tables and objects and their
sensitivity/vulnerability:
o the pwTable contains objects to configure PW parameters on
a Provider Edge (PE) device. Unauthorized access to objects
in this table, could result in disruption of traffic on
the network. The objects pwUpDownNotifEnable and
pwNotifRate control the reports from the network element
to the EMS. Unauthorized access to these objects could
result in disruption of configuration and status change
reporting, resulting mis-view of the network conditions.
The use of stronger mechanisms such as SNMPv3 security
should be considered where possible. Specifically,
SNMPv3 VACM and USM MUST be used with any v3 agent which
implements this MIB module. Administrators should consider
whether read access to these objects should be allowed,
since read access may be undesirable under certain
circumstances.
Some of the readable objects in this MIB module "i.e., objects
with a MAX-ACCESS other than not-accessible" may be considered
sensitive or vulnerable in some network environments. It is thus
important to control even GET and/or NOTIFY access to these
objects and possibly to even encrypt the values of these objects
when sending them over the network via SNMP. These are the tables
and objects and their sensitivity/vulnerability:
o the pwTable, pwPerfCurrentTable, pwPerfIntervalTable,
pwPerf1DayIntervalTable, pwIndexMappingTable and
pwPeerMappingTable collectively show the pseudo wire
connectivity topology and its performance characteristics.
If an Administrator does not want to reveal this
information, then these tables should be
considered sensitive/vulnerable.
SNMP versions prior to SNMPv3 did not include adequate security.
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 module.
It is RECOMMENDED that implementers consider the security features
as provided by the SNMPv3 framework "see [RFC3410], section 8",
Zelig et al Expires December 2006 [page 51]
Pseudo Wire (PW) Management June 2006
Information Base
including full support for the SNMPv3 cryptographic mechanisms
"for authentication and privacy".
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module, 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.
10 IANA considerations
10.1 IANA considerations for PW-STD-MIB
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
pwStdMIB { transmission XXXX }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXXX" under the 'transmission'
subtree and to record the assignment in the SMI Numbers registry.
When the assignment has been made, the RFC Editor is asked to
replace "XXXX" (here and in the MIB module) with the assigned
value and to remove this note.
IANA is also requested to register a value for a PW type in the
IANAifType-MIB.
10.2 IANA considerations for IANA-PWE3-MIB
The IANA-PWE3-MIB those initial version is included in this
document, is IANA controlled. Each new assignment of PW type or PW
PSN type made by IANA based on the procedures described in
[RFC4446] should be documented in the online version of IANA-PWE3-
MIB.
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
ianaPwe3MIB { transmission XXXX }
