Internet Engineering Task Force E. Stephan Internet-Draft France Telecom Intended status: Standards Track Q. Zhao Created: October 25, 2009 Huawei Technology Expires: March 25, 2009 D. King Old Dog Consulting Definitions of Textual Conventions for Path Computation Element draft-ietf-pce-tc-mib-05 Abstract 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 Textual Conventions to represent commonly used Path Computation Element (PCE) management information. The intent is that these TEXTUAL CONVENTIONS (TCs) will be imported and used in PCE related MIB modules to avoid duplicating conventions.

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 Textual Conventions to represent commonly used Path Computation Element (PCE) management information. The intent is that these TEXTUAL CONVENTIONS (TCs) will be imported and used in PCE related MIB modules to avoid duplicating conventions. For an introduction to the concepts of PCE, see [RFC4655]. 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]. Stephan, et al. [Page 2] draft-ietf-pce-tc-mib-05 October 2009 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. Structure of the MIB Module This MIB module defines PCE common SMI items. It defines the nodes for the homing of the MIB modules and TC to be imported and used in PCE related MIB modules. PCE management information is arranged into 3 modules: o PCE-TC-STD-MIB (defined in this memo) defined the root for homing Standard PCE MIB modules; o PCE-DISC-STD-MIB defines the management information for monitoring PCE entities discovery; o PCE-PCEP-STD-MIB defines the information for managing PCE communication protocol; 4. PCE Textual Conventions MIB Definitions PCE-TC-STD-MIB DEFINITIONS ::= BEGIN IMPORTS MODULE-IDENTITY, experimental FROM SNMPv2-SMI TEXTUAL-CONVENTION FROM SNMPv2-TC; pceTCDraftMIB MODULE-IDENTITY LAST-UPDATED "200903020000Z" -- March 2, 2009 ORGANIZATION "Path Computation Element (PCE) Working Group" CONTACT-INFO " Stephan Emile France Telecom Email: emile.stephan@orange-ftgroup.com Stephan, et al.

In particular, it defines Textual Conventions to represent commonly used Path Computation Element (PCE) management information. The intent is that these TEXTUAL CONVENTIONS (TCs) will be imported and used in PCE related MIB modules to avoid duplicating conventions." ::= { pceStdMIB 1 } pceStdMIB OBJECT IDENTIFIER ::= { experimental 9999 } -- RFC Editor: Please see the IANA Considerations Section. -- 'experimental 9999' is a temporary root for running smilint. -- 'pceStdMIB' will be homed in 'mib-2' -- Textual Conventions (sorted alphabetically). PcePcepIdentifier ::= TEXTUAL-CONVENTION DISPLAY-HINT "1d.1d.1d.1d:1d:1d" STATUS current DESCRIPTION "The LDP identifier is a six octet quantity which is used to identify a PCE client." SYNTAX OCTET STRING (SIZE (0..6)) PceRoutingDomainID ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A PCE-DOMAINS information element or a A PCE-DEST-DOMAINS information element carries the identifier of a routing domain (area, as) which type depends on both the routing protocol and on the version of Internet protocol in use in this routing domain. This TC defines a common SMI type for the different kinds of routing domain identifiers. A PceRoutingDomainID value is always interpreted within the context of an AddressFamilyNumbers value. Every usage of the PceRoutingDomainID textual convention is required to specify the AddressFamilyNumbers object which provides the context. The value of an PceRoutingDomainID object must always be consistent with the value of the associated AddressFamilyNumbers object. Stephan, et al. [Page 4] draft-ietf-pce-tc-mib-05 October 2009 Following is the mapping between AddressFamilyNumbers type and PceRoutingDomainID size: ipV4(1): PceRoutingDomainID is an InetAddressIPv4 corresponding to the name of an OSPF area; ipV6(2): PceRoutingDomainID is an InetAddressIPv6 corresponding to the name of an OSPF area; nsap(3): PceRoutingDomainID type is OCTET STRING (SIZE (0..20)), corresponding to the name of an ISIS area (see RFC 1195); asNumber(18) PceRoutingDomainID type is OCTET STRING (SIZE (2)) corresponding to the name of an Autonomous System. " SYNTAX OCTET STRING (SIZE (0..20)) END 5. Security Considerations This module defines only textual conventions. As security considerations can only be written in MIB modules that define management objects this document has no impact on the security of the Internet. 6. IANA Considerations IANA is requested to make a MIB OID assignment for pceStdMIB under the mib-2 branch. PCE related standards track MIB modules should be homed under the pceStdMIB subtree. This document also requests IANA to assign { pceStdMIB 1 } to the PCE-TC-STD-MIB specified in this document. 7. References 7.1.
