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
pseudowire (PW) services for transmission over a Packet Switched
Network (PSN) [RFC3931] [RFC4447]. This MIB module provides generic
management of PWs that is common to all types of PSN and PW services
defined by the IETF PWE3 Working Group.
2. 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].
3. Conventions
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 RFC 2119 [BCP14].
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.
4. Overview
The PWE3 MIB modules architecture provides a layered modular model
into which any supported emulated service can be connected to any
supported PSN type. This specific MIB module provides the glue for
mapping between the emulated service onto the native PSN service. As
such, the defining of a PW emulated service requires the use of at
least three types of MIB modules.
Starting from the emulated service, the first type is a service-
specific module, which is dependent on the emulated signal type.
These modules are defined in other documents.
The second type is this module, 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 third type of module is a PSN-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.
5. Structure of the MIB Module
The MIB module consists of six tables:
- The generic configuration and status monitoring objects that are
common to all service types and PSN types (pwTable).
- The PW Performance Current Table (pwPerfCurrentTable) contains PW
statistics for the current 15-minute period.
- The PW Performance Interval Table (pwPerfIntervalTable) contains PW
statistics for historical intervals (usually 96 15-minute entries
to cover a 24-hour period).
- The PW Performance 1-day Interval Table (pwPerf1DayIntervalTable)
contains PW statistics for historical intervals accumulated per
day. Usually 30 1-day entries to cover a monthly period.
- The mapping table (pwIndexMappingTable) enables the reverse mapping
of the unique PWid parameters [peer IP, PW type, and PW ID] and the
pwIndex.
- The mapping table (pwGenFecIndexMappingTable) enables the reverse
mapping of unique PWid parameters used in genFecSignaling
[pwGroupAttachmentID, pwLocalAttachmentID, and pwPeerAttachmentID]
and the pwIndex.
This MIB module uses Textual Conventions from [RFC2578], [RFC2579],
[RFC2580], [RFC2863], [RFC3411], [RFC3593], [RFC3705], [RFC4001], and
[RFC5542], and references [RFC3413], [RFC4623], and [RFC4720].
6. 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 (manually assigned)
PW.
2) The agent MAY create a row in the pwTable if a signaling message
has been received from a peer node with signaling identification
parameters that are not already known to the local node (i.e.,
there is no related entry created by the operator with matching
parameters). This mode is OPTIONAL.
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 then creates the rows in the (locally supported)
performance tables and reverse-mapping tables in PW-STD-MIB
module.
7. Relations to Other PWE3 MIB Modules
- Based on the PSN type defined for the PW, a row is created in the
PSN-specific module (for example, [RFC5602]) and associated to the
PW table by the common pwIndex.
- Based on the PW type defined for the PW, a row is created in the
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'.
8. Relations to the IF-MIB
The PW in general is not an ifIndex [RFC2863] on its own, for 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 Circuit Emulation Service over Packet (CEP). In that
case, the PW itself is not an ifIndex; however, the PW-STD-CEP-MIB
module associates the PW to the ifIndex of the path to be emulated.
In some cases, the PW will be associated to an ifIndex representing a
virtual interface. An example is Virtual Private LAN Service (VPLS)
where the PW emulates a logical interface of a (logical) bridge. The
physical ports' association to the VPLS instance is defined in the
non-PW MIB modules 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 (246) will be used in the
ifTable in this case.
When the PW is managed as an ifIndex, by default it SHOULD NOT be
stacked, i.e., this ifIndex SHOULD NOT be layered above the
respective PSN tunnel ifIndex or the attachment circuit ifIndex or
the interface carrying the attachment circuit.
Note that the ifIndex that carries the PW toward/from the PSN is 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 MIB modules that
control the PSN tunnels.
9. PW Notifications
This MIB module includes notifications for PW entering the up or down
state, in accordance with the guidelines for interface notifications
as described in [RFC2863]. Implementers should be aware that in many
systems, it is desired to correlate notifications, such that
notifications will not be emitted if notifications from a higher
level (such as ports or tunnels) are already in effect. Specifically
for PWs, it is anticipated that most network's equipment failures
turn into lowerLayerDown state at the PW level, where a notification
has already been emitted from a higher level.
When a PW is represented as an ifIndex, it is RECOMMENDED that PW
notifications be turned off, to avoid duplication with the ifIndex
status change notifications.
10. 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 Multiprotocol Label
Switching (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 setup.
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 (for
example, [CEPMIB]) and the PW-MPLS-STD-MIB module [RFC5602].
In the PW-STD-MIB module:
In pwTable:
{
pwIndex 5,
pwType cep,
pwOwner pwIdFecSignaling,
pwPsnType mpls,
pwSetUpPriority 0, -- Highest
pwHoldingPriority 0, -- Highest

11. IANA PWE3 MIB Module
This section contains the initial version of the IANA-PWE3-MIB. IANA
has updated this MIB module based on expert review as defined in
[RFC5226]. 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 current
IANA-PWE3-MIB contains PW types as requested in [RFC4446] and
[RFC4863].

DESCRIPTION
"A row in this table represents a pseudowire (PW) virtual
connection across a packet network. It is indexed by
pwIndex, which uniquely identifies a singular
connection.
A row can be created by an operator command from a
management plan of a PE, by signaling, or due to auto-
discovery process. An operator's command can be issued via
a non-SNMP application; in such case, a row will be created
implicitly by the agent.
The read-create objects in this table are divided into
three categories:
1) Objects that MUST NOT be changed after row activation.
These are objects that define basic properties of the
PW (for example type, destination, etc.).
2) Objects that MAY be changed when the PW is
defined as not active. A change of these objects involves
re-signaling of the PW or it might be traffic affecting.
PW not active is defined as one of the following
conditions:
a) The pwRowStatus is notInService(2).
b) The pwRowStatus is notReady(3).
c) The pwAdminStatus is down(2).
If the operator needs to change one of the values for an
active row, the operator can either set the pwRowStatus to
notInService(2) or set pwAdminStatus to down(2).
Signaling (or traffic) is initiated again upon setting
the pwRowStatus to active(1) or setting the pwAdminStatus
to up(1) or testing(3), respectively.
3) Objects that MAY be changed at any time.
A PW MAY have an entry in the ifTable in addition to the
entry in this table. In this case, a special ifType for PW
will be set in the ifTable, and the ifIndex in the ifTable
of the PW will be set in the pwIfIndex object in this table.
By default, all the read-create objects MUST NOT be
changed after row activation, unless specifically indicated
in the individual object description.
Manual entries in this table SHOULD be preserved after a
reboot; the agent MUST ensure the integrity of those
entries. If the set of entries of a specific row are found
to be inconsistent after reboot, the PW pwOperStatus MUST
be declared as notPresent(5).

signaled and it MAY be set to zero.
For implementations that support the pwIndexMappingTable,
a non-zero value is RECOMMENDED, even if this
identifier is not signaled. This is so that reverse
mappings can be provided by pwIndexMappingTable and
pwPeerMappingTable. It is therefore RECOMMENDED that the
value of this pwID be unique (or if pwPeerAddrType is not
'unknown', at least [pwType, pwID, pwPeerAddrType, pwPeerAddr]
is unique.)"

13. Security Considerations
It is clear that this MIB module is potentially useful for monitoring
PW-capable PEs. This MIB module can also be used for configuration
of certain objects, and anything that can be configured can be
incorrectly configured, with potentially disastrous results.
There are a 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 that 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, pwPeerMappingTable,
and pwGenFecIndexMappingTable collectively show the pseudowire
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),
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.
14. IANA Considerations
14.1. ifType for PW
IANA has assigned a value (246) for PW in the IANAifType-MIB called
ifPwType.
14.2. PW MIB Modules OBJECT IDENTIFIER Values
A PW may appear as ifIndex in the ifTable, and therefore the pwStdMIB
OBJECT IDENTIFIER has been assigned under the 'transmission' subtree,
as the common practice in assigning OBJECT IDENTIFIERs for MIB
modules representing entities in the ifTable.
All other MIB modules related to PW management SHOULD be assigned
under the 'mib-2' subtree; individual requests will appear in the MIB
module memo's IANA Considerations section.
14.3. 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 246 }
14.4. IANA Considerations for 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 { mib-2 174 }
