    Pseudowire (PW) over MPLS PSN Management Information Base (MIB)

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 describes a MIB module for PW operation over
   Multiprotocol Label Switching (MPLS) Label Switching Routers (LSRs).

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

1.  Introduction

   This document describes a model for managing pseudowire services for
   transmission over different flavors of MPLS tunnels.  The general PW
   MIB module [RFC5601] defines the parameters global to the PW
   regardless of the underlying Packet Switched Network (PSN) and
   emulated service.  This document is applicable for PWs that use MPLS
   PSN type in the PW-STD-MIB.

   This document describes the MIB objects that define pseudowire
   association to the MPLS PSN, in a way that is not specific to the
   carried service.

   Together, [RFC3811] and [RFC3812] describe the modeling of an MPLS
   tunnel, and a tunnel's underlying cross-connects.  This MIB module
   supports MPLS-TE PSN, non-TE MPLS PSN (an outer tunnel created by the
   Label Distribution Protocol (LDP) or manually), and MPLS PW label
   only (no outer tunnel).

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
