Standards Track [Page 2] + +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.

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. + +6.
