Status of this Memo
This document is an Internet-Draft and is in full conformance with
all provisions of Section 10 of RFC 2026.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
other groups may also distribute working documents as Internet-
Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."

Abstract
This document defines a Management Information Base (MIB) module
which contains Textual Conventions to represent commonly used
Generalized Multiprotocol Label Switching (GMPLS) management
information. The intent is that these TEXTUAL CONVENTIONS (TCs) will
be imported and used in GMPLS related MIB modules that would
otherwise define their own representations.

1. Introduction
This document defines a MIB module which contains Textual Conventions
for Generalized Multiprotocol Label Switching (GMPLS) networks.
These Textual Conventions should be imported by MIB modules which
manage GMPLS networks.
This MIB module supplements the MIB module in [TCMIB] that defines
Textual Conventions for Multiprotocol Label Switching (MPLS)
Management. [TCMIB] may continue to be used without this MIB module
in networks that support only MPLS.
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 [RFC2119].
Comments should be made directly to the CCAMP mailing list at
ccamp@ops.ietf.org.
For an introduction to the concepts of GMPLS, see [GMPLSArch].
2. The SNMP 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].

DESCRIPTION
"Copyright (C) The Internet Society (2004). This version of this
MIB module is part of RFCXXX; see the RFC itself for full legal
notices.
This MIB module defines Textual Conventions for concepts used in
Generalized Multiprotocol Label Switching (GMPLS) networks."
-- Revision history.
REVISION
"200406010900Z" -- 1 June 2004 9:00:00 GMT"
DESCRIPTION
"Initial version published as part of RFC XXXX."
-- Please see the IANA Considerations Section.
-- The requested gmplsStdMIB subId is xx, i.e.
::= { gmplsStdMIB xx }

Internet Draft draft-ietf-ccamp-gmpls-tc-mib-05.txt June 2004
gmplsStdMIB OBJECT IDENTIFIER
-- This object identifier needs to be assigned by IANA.
-- Since mpls has been assigned an ifType of 166 we recommend
-- that this OID be 166 as well, i.e.
::= { transmission XXX }
-- Textual Conventions (sorted alphabetically).
GmplsFreeformLabel ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This value represents a freeform generalized MPLS Label. This
can be used to represent label types which are not standard
in the drafts. It may also be used by systems that do not
wish to represent the labels using the specific label types."
SYNTAX OCTET STRING (SIZE (0..64))
GmplsGeneralizedLabelTypes ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Determines the interpretation that should be applied to a
label."
SYNTAX INTEGER {
gmplsMplsLabel(1),
gmplsPortWavelengthLabel(2),
gmplsFreeformGeneralizedLabel(3),
gmplsSonetLabel(4),
gmplsSdhLabel(5),
gmplsWavebandLabel(6)
}
GmplsSegmentDirection ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The direction of data flow on an LSP segment with respect to the
head of the LSP.
Where an LSP is signaled using a conventional signaling
protocol, the 'head' of the LSP is the source of the signaling
(also known as the ingress) and the 'tail' is the destination
(also known as the egress). For unidirectional LSPs, this
usually matches the direction of flow of data.
For manually configured unidirectional LSPs the direction of the
LSP segment matches the direction of flow of data. For manually
configured bidirecitonal LSPs, an arbitrary decision must be
made about which LER is the 'head'."
SYNTAX INTEGER {
forward(1),
reverse(2)
}

4. Security Considerations
This module does not define any management objects. Instead, it
defines a set of textual conventions which may be used by other GMPLS
MIB modules to define management objects.
Meaningful security considerations can only be written in the MIB
modules that define management objects. Therefore, this document has
no impact on the security of the Internet.
5. IANA Considerations
IANA is requested to make a MIB OID assignment under the transmission
branch, that is, assign the gmplsStdMIB under { transmission 166 }.
This sub-id is requested because 166 is the ifType for mpls(166) and
is available under transmission.
In the future, GMPLS related standards track MIB modules should be
rooted under the mplsStdMIB (sic) subtree. IANA is requested to
manage that namespace. New assignments can only be made via a
Standards Action as specified in [RFC2434].
This document also requests IANA to assign { gmplsStdMIB xx } to the
GMPLS-TC-STD-MIB specified in this document. The value 1 is
suggested.
