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] [RFC3811] that defines
   Textual Conventions for Multiprotocol Label Switching (MPLS)
   Management. [TCMIB] [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 2119,
   reference [RFC2119].

   Comments should be made directly to the CCAMP mailing list at
   ccamp@ops.ietf.org.

2. The SNMP 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].

     -- This object identifier needs to be assigned by IANA.

        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 GMPLS 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 make a root MIB OID assignment objects in this MIB module
   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. 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 is has been requested
   to manage that namespace.  New assignments can only be made via a
   Standards Action as specified in [RFC2434].

   This document also requests

   The IANA to assign has assigned { gmplsStdMIB xx mplsStdMIB 1 } to the
   GMPLS-TC-STD-MIB specified in this document. The value 1 is
   suggested. MPLS-TC-STD-MIB.
