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.

Internet-Draft PCE-TC-STD-MIB March 2009
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 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].
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", "NOT RECOMMENDED", "MAY", and
"OPTIONAL", when they appear in this document, are to be interpreted
as described in BCP 14, RFC 2119 [RFC2119].
4. 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;
Stephan Expires September 3, 2009 [Page 3]
Internet-Draft PCE-TC-STD-MIB March 2009
o PCE-PCEP-STD-MIB defines the information for managing PCE
communication protocol;

DESCRIPTION
"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

::= { 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.
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))

6. 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.
7. 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.
