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 [RFC3811] that defines
Textual Conventions for Multiprotocol Label Switching (MPLS)
Management. [RFC3811] may continue to be used without this MIB module
in networks that support only MPLS.
Comments should be made directly to the CCAMP mailing list at
ccamp@ops.ietf.org.
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, RFC 2119,
reference [RFC2119].
For an introduction to the concepts of GMPLS, see [GMPLSArch].
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].

DESCRIPTION
"Copyright (C) The Internet Society (2004). The
initial version of this MIB module was published
in RFC xxxx. For full legal notices see the RFC
itself or see:

Generalized Multiprotocol Label Switching (GMPLS) networks."

"200410080001Z" -- 8 October 2004 00:00:01 GMT
DESCRIPTION
"Initial version published as part of RFC XXXX."
-- Please see the IANA Considerations Section.
-- This MIB module is contained in the OID sub-tree
-- rooted at mplsStdMIB.
-- The requested mplsStdMIB subId is xx, i.e.
::= { mplsStdMIB xx }

-- 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."
REFERENCE
"Generalized Multi-Protocol Label Switching (GMPLS) Signaling
Functional Description, RFC 3471."
SYNTAX OCTET STRING (SIZE (0..64))
GmplsGeneralizedLabelTypes ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Determines the interpretation that should be applied to a
label."
REFERENCE
"Generalized Multi-Protocol Label Switching (GMPLS) Signaling
Functional Description, RFC 3471."
SYNTAX INTEGER {
gmplsMplsLabel(1),
gmplsPortWavelengthLabel(2),
gmplsFreeformGeneralizedLabel(3),
gmplsSonetLabel(4),
gmplsSdhLabel(5),

}
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'."

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 MPLS
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 root MIB objects in this MIB module
under the mplsStdMIB subtree by assigning an OID to
gmplsTCStdMIB.
In the future, GMPLS related standards track MIB modules should be
rooted under the mplsStdMIB (sic) subtree. IANA has been requested
to manage that namespace. New assignments can only be made via a
Standards Action as specified in [RFC2434].
The IANA has assigned { mplsStdMIB 1 } to the MPLS-TC-STD-MIB.
