2.0 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 used in IETF PW and PW-
related MIBs.
Comments should be made directly to the MPLS mailing list at
pwe3@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 RFC-2119 [BCP14].
For an introduction to the concepts of Pseudo-Wires, see [PWREQ] and
[PWFRM].
3.0 Terminology
This document uses terminology from the document describing the
Pseudo-Wires Requirements [PWE3REQ].
4.0 The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
- An overall architecture, described in RFC 2271 [SNMPArch].
- Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in RFC
1155 [SMIv1], RFC 1212 [SNMPv1MIBDef] and RFC 1215 [SNMPv1Traps].
The second version, called SMIv2, is described in RFC 1902 [SMIv2],
RFC 1903 [SNMPv2TC] and RFC 1904 [SNMPv2Conf].
- Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in RFC 1157 [SNMPv1]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [SNMPv2c] and RFC 1906
[SNMPv2TM]. The third version of the message protocol is called
SNMPv3 and described in RFC 1906 [SNMPv2TM], RFC 2272 [SNMPv3MP] and
RFC 2574 [SNMPv3USM].
Nadeau et al. Expires August 2002 [Page 2]
Internet Draft PW-TC MIB February 25, 2002
- Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in RFC 1157 [SNMPv1]. A second set of protocol operations
and associated PDU formats is described in RFC 1905 [SNMPv2PO].
- A set of fundamental applications described in RFC 2273
[SNMPv3App] and the view-based access control mechanism described in
RFC 2575 [SNMPv3VACM].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.

DESCRIPTION
"Indicate the operational ststus of the PW VC.
- up: Ready to pass packets.
- down: If PW signaling has not yet finished, or
indications available at the service
level indicate that the VC is not
passing packets.
- testing: If AdminStatus at the VC level is set to
test.
- dormant: The VC is not available because of the
required resources are occupied VC with
higher priority VCs .
- notPresent: Some component is missing to accomplish
the set up of the VC.
- lowerLayerDown: The underlying PSN or outer tunnel is not
in OperStatus 'up'.
