RFC 7420 PCEP MIB December 2014
1. Introduction
The PCE defined in [RFC4655] is an entity that is capable of
computing a network path or route based on a network graph and
applying computational constraints. A PCC may make requests to a PCE
for paths to be computed.
PCEP is the communication protocol between a PCC and PCE and is
defined in [RFC5440]. PCEP interactions include path computation
requests and path computation replies as well as notifications of
specific states related to the use of a PCE in the context of
Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS)
Traffic Engineering (TE).
This memo defines a portion of the MIB for use with network
management protocols in the Internet community. In particular, it
defines a MIB module that can be used to monitor PCEP interactions
between a PCC and a PCE, or between two PCEs.
The scope of this document is to provide a MIB module for the PCEP
base protocol defined in [RFC5440]. Extensions to the PCEP base
protocol are beyond the scope for this document.
1.1. Requirements Language
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 BCP 14 [RFC2119].
1.2. Terminology
This document uses the terminology defined in [RFC4655] and
[RFC5440]. In particular, it uses the following acronyms.
o Path Computation Request (PCReq) message.
o Path Computation Reply (PCRep) message.
o Notification (PCNtf) message.
o Error (PCErr) message.
o Request Parameter (RP) object.
o Synchronization Vector (SVEC) object.
o Explicit Route Object (ERO).
Koushik, et al. Standards Track [Page 3]
RFC 7420 PCEP MIB December 2014
This document uses the term "PCEP entity" to refer to a local PCEP
speaker, "peer" to refer to a remote PCEP speaker, and "PCEP speaker"
where it is not necessary to distinguish between local and remote.
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. PCEP MIB Module Architecture
The PCEP MIB module contains the following information:
a. PCE and PCC local entity status (see pcePcepEntityTable).
b. PCEP peer information (see pcePcepPeerTable).
c. PCEP session information (see pcePcepSessTable).
d. Notifications to indicate PCEP session changes.
The PCEP MIB module is limited to "read-only" access except for
pcePcepNotificationsMaxRate, which is used to throttle the rate at
which the implementation generates notifications.
3.1. pcePcepEntityTable
The PCEP MIB module may contain status information for multiple
logical local PCEP entities. There are several scenarios in which
there may be more than one local PCEP entity, including the
following.
o A physical router, which is partitioned into multiple virtual
routers, each with its own PCC.
o A PCE device that front ends a cluster of compute resources, each
with a different set of capabilities that are accessed via
different IP addresses.
Koushik, et al. Standards Track [Page 4]
RFC 7420 PCEP MIB December 2014
The pcePcepEntityTable contains one row for each local PCEP entity.
Each row is read-only and contains current status information, plus
the PCEP entity's running configuration.
The pcePcepEntityTable is indexed by pcePcepEntityIndex, which also
acts as the primary index for the other tables in this MIB module.
3.2. pcePcepPeerTable
The pcePcepPeerTable contains one row for each peer that the local
PCEP entity knows about. Each row is read-only and contains
information to identify the peer, the running configuration relating
to that peer, and statistics that track the messages exchanged with
that peer and its response times.
A PCEP speaker is identified by its IP address. If there is a PCEP
speaker in the network that uses multiple IP addresses, then it looks
like multiple distinct peers to the other PCEP speakers in the
network.
The pcePcepPeerTable is indexed first by pcePcepEntityIndex, then by
pcePcepPeerAddrType and pcePcepPeerAddr. This indexing structure
allows each local PCEP entity to report its own set of peers.
Since PCEP sessions can be ephemeral, pcePcepPeerTable tracks a peer
even when no PCEP session currently exists to that peer. The
statistics contained in pcePcepPeerTable are an aggregate of the
statistics for all successive sessions to that peer.
To limit the quantity of information that is stored, an
implementation MAY choose to discard a row from pcePcepPeerTable if
and only if no PCEP session exists to the corresponding peer.
3.3. pcePcepSessTable
The pcePcepSessTable contains one row for each PCEP session that the
PCEP entity (PCE or PCC) is currently participating in. Each row is
read-only and contains the running configuration that is applied to
the session, plus identifiers and statistics for the session.
The statistics in pcePcepSessTable are semantically different from
those in pcePcepPeerTable since the former applies to the current
session only, whereas the latter is the aggregate for all sessions
that have existed to that peer.
Although it is forbidden per [RFC5440] to have more than one active
PCEP session between a given pair of PCEP entities at any one time,
there is a window during session establishment where the
Koushik, et al. Standards Track [Page 5]
RFC 7420 PCEP MIB December 2014
pcePcepSessTable may contain two rows for a given peer, one
representing a session initiated by the local PCEP entity and one
representing a session initiated by the peer. If either of these
sessions reaches an active state, then the other is discarded.
The pcePcepSessTable is indexed first by pcePcepEntityIndex, then by
pcePcepPeerAddrType and pcePcepPeerAddr, and finally by
pcePcepSessInitiator. This indexing structure allows each local PCEP
entity to report its own set of active sessions. The
pcePcepSessInitiator index allows two rows to exist transiently for a
given peer, as discussed above.
3.4. PCEP Notifications
The PCEP MIB module contains notifications for the following
conditions.
a. pcePcepSessUp: PCEP session has gone up.
b. pcePcepSessDown: PCEP session has gone down.
c. pcePcepSessLocalOverload: Local PCEP entity has sent an overload
PCNtf on this session.
d. pcePcepSessLocalOverloadClear: Local PCEP entity has sent an
overload-cleared PCNtf on this session.
e. pcePcepSessPeerOverload: Peer has sent an overload PCNtf on this
session.
f. pcePcepSessPeerOverloadClear: Peer has sent an overload-cleared
PCNtf on this session.
3.5. Relationship to Other MIB Modules
The PCEP MIB module imports the following textual conventions from
the INET-ADDRESS-MIB defined in RFC 4001 [RFC4001]:
o InetAddressType
o InetAddress
PCEP relies on existing protocols that have specialized MIB objects
to monitor their own activities. Consequently, this document
considers that the monitoring of underlying protocols is out of scope
of the PCEP MIB module.
Koushik, et al. Standards Track [Page 6]
RFC 7420 PCEP MIB December 2014
3.6. Illustrative Example
The following diagram illustrates the relationships between
pcePcepEntityTable, pcePcepPeerTable, and pcePcepSessTable.

Consider the case where a PCReq message is received by a PCE
that contains the SVEC object referring to M synchronized
path computation requests. If after the expiration of the
SyncTimer all the M path computation requests have not been
received, a protocol error is triggered and the PCE MUST
cancel the whole set of path computation requests.
Koushik, et al. Standards Track [Page 15]
RFC 7420 PCEP MIB December 2014
The aim of the SyncTimer is to avoid the storage of unused
synchronized requests should one of them get lost for some

5. Security Considerations
The pcePcepNotificationsMaxRate object defined in this MIB module has
a MAX-ACCESS clause of read-write. 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 opens devices to attack. In particular,
pcePcepNotificationsMaxRate may be used improperly to stop
notifications being issued or to permit a flood of notifications to
be sent to the management agent at a high rate.
All 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. The sensitivity/vulnerability arises because,
collectively, these objects provide information about the amount and
frequency of path computation requests and responses within the
network and can reveal some aspects of its configuration.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
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.
Implementations SHOULD provide the security features described by the
SNMPv3 framework (see [RFC3410]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for
authentication and privacy via the User-based Security Model (USM)
[RFC3414] with the AES cipher algorithm [RFC3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
Koushik, et al. Standards Track [Page 49]
RFC 7420 PCEP MIB December 2014
[RFC5591] in combination with a secure transport such as SSH
[RFC5592] or TLS/DTLS [RFC6353].
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.
