Internet-Draft Manage ATM over PSN October 2008
1. Introduction
This document describes a model for managing "emulated" ATM services
over a Packet Switched Network(PSN).
The document follows the requirements for Pseudo-Wire Emulation Edge-
to-Edge [PWREQ], and closely related to [ATMENCAP] and [ATMTRANS]
which describe the encapsulation of ATM signals and provide the
Emulation Service over a Packet Switched Network.
The ATM management model consists of several MIB modules, following
the layering model described in the PWE3 Architecture [PWARCH]
document. The ATM MIB module described in this document works
closely with the MIB modules described in [AToMTC], [AToM], [IFMIB],
[PWMIB] and the textual conventions defined in [PWTC]. The
conceptual layering and relationship among all those is described in
Figure 1 and in the "Relation to other PW-MIB modules" section listed
below. AN ATM connection will be a pseudo-wire (PW) connection. It
will not be treated as an interface and will therefore not be
represented in the ifTable.

2. Conventions
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].
3. Terminology
This document follows the terminology used in PW Architecture
[PWARCH].
PSN bound References the traffic direction where a ATM Cell
is received, adapted to packet, assigned a PW
label, and sent into the PSN. Within the MIB
objects it is called outbound.
CE bound The direction where packets are received
from the PSN, cells are reconstructed from the
packet payloads, and sent into the ATM Network
as cells. Within the MIB objects it is called
inbound.
Adaptation Refers to the method of adapting a "foreign"
communications protocol such that it can be
carried by a packet switched net (the PSN). For
example, in a ATM service the foreign protocol
is ATM. The PSN may be MPLS.
PSN Packet Switched Network.
PSN Tunnel A general term indicating a virtual connection
between the two PW edge devices. In practice
this connection is not limited to path-oriented
types of PSNs such as MPLS. An example of a non-
path-oriented PSN is an IP PSN.
4. 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
Nicklass, et al. Expires April 15, 2009 [Page 4]
Internet-Draft Manage ATM over PSN October 2008
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].
5. Overview
This MIB module is designed to satisfy the following requirements and
constraints:
o - Fit within the architecture defined by [PWARCH] and [PWMIB].
o - Fit within the model for VP/VC definitions and management
concept as defined in the [AToM] MIB.
o - Supports manually configured ATM PWs
o - Supports automatically configured ATM PWs
o - The MIB module enables the use of any PSN type
o - The MIB module supports point-to-point ATM PW connections.
Point-to-multipoint and multipoint-to-point connections are for
future study.
o - The MIB module allows configuration of all the parameters needed
to establish a PW to carry ATM cells.
o - The MIB module reports: ATM performance metrics for the ATM PW.
This includes cells transmit, Cells dropped, Cells received, and
unknownCells. In addition it reports performance metrics at
packet level.
o - ATM OAM cell support.
o - The MIB module does not consider ILMI support
6. Relation to other PW-MIB modules
The MIB structure for defining a PW service is composed of three
layers of MIB modules functioning together. This general model is
defined in the PWE3 Architecture [PWARCH]. The layering model is
intended to sufficiently isolate PW services from the underlying PSN
layer that carries the emulated service. This is done at the same
time as providing a standard means for connecting any supported
services to any supported PSNs.
The first layer known as the service layer contains service-specific
modules such as the one defined in this document. These modules
define service-specific management objects that interface or
Nicklass, et al. Expires April 15, 2009 [Page 5]
Internet-Draft Manage ATM over PSN October 2008
collaborate with existing MIB modules for the native version of the
service. The service-specific module "glues" the standard module to
the PWE MIB framework.
The next layer of the PWE MIB framework is comprised of the PW-MIB
module [PWMIB]. This module is used to configure general parameters
of PW connections that are common to all types of emulated services
and PSNs. This layer is connected to the service-specific layer
above, and the PSN layer below.
The PSN layer provides PSN-specific modules for each type of PSN.
These modules associate the PW with one or more "tunnels" that carry
the service over the PSN. These modules are defined in other
documents. This module is used to "glue" the PW service to the
underlying PSN-specific MIB modules. In the case of MPLS, for
example, the PW-MPLS MIB [PWMPLSMIB] is used to connect the PW
service to either the MPLS-LDP [LDPMIB] or MPLS-TE [TEMIB] MIBs.
[PWTC] defines some of the object types used in these modules.
7. ATM-PW MIB Usage
This section provides an example of using the MIB objects described
in section 9 to set up an ATM PW. While this example is not meant to
illustrate every permutation of the MIB, it is intended as an aid in
the understanding of some key concepts. It is meant to be read after
going through the MIB itself. See [PWMIB] for an example of setting
up a PSN Tunnel.
The following example illustrates how a user will set up an AAL5 ATM
PW on a switch/router with cells entering the switch/router through
ATM Interface with IfIndex 1000 [IFMIB], VPI 1 and VCI 100 (from ATM
Network to PSN - outbound direction) and on the way back, it goes out
of the switch/router through ATM Interface 1000 with VPI 1 and VCI
100 (PSN to ATM Network - inbound direction)
First create an entry in PW MIB with pwType atmAal5SduVcc(2), then
create entries in pwAtmCfg table, inbound and outbound tables.

8. Structure of the MIB module
This MIB consists of 4 types of tables;
It is important to note that the TrafficParamDescr Table is not
defined as part of this MIB although an object pointing to such
table entry exist in all configuration tables of this MIB module.
Users can refer to any ATM TrafficDescr (TD) Table if there is a
need to overwrite the TD assigned to the ATM endpoint in the ATM
service MIB [AToM].
- PW ATM Cfg Table A table for generic parameters for ATM PW
configuration that is applicable for each ATM PW.
- PW ATM Outbound Table There are 2 tables to configure an
outbound ATM PW depending on the type of service. One table for
1: 1 service, and the other for N:1 service and transparent cell
mode [ATMTRANS].
- PW ATM Inbound Table There are 2 tables to configure an inbound
ATM PW depending on the type of service. One table for 1: 1
service, and the other for N:1 service and transparent cell mode.
Nicklass, et al. Expires April 15, 2009 [Page 7]
Internet-Draft Manage ATM over PSN October 2008
- PW ATM Perf Table There are 3 tables each contains the relevant
time dependent statistics for an ATM PW Entry. There is a current
table, 15 minutes interval table and one day interval table. The
tables are aligned with statistic model of other PW services.

10. Security considerations
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
The pwAtmOutboundTable, pwAtmInboundTable, pwAtmCfgTable,
pwAtmOutboundNto1Table, and pwAtmInboundNto1Table contain objects of
ATM PW parameters on a Provider Edge (PE) device. Unauthorized
access to objects in these tables could result in disruption of
traffic on the network.
The use of stronger mechanisms such as SNMPv3 security should be
considered where possible. Specifically, SNMPv3 VACM and USM MUST be
used with any SNMPV3 agent, which implements this MIB module.
Administrators should consider whether read access to these objects
should be allowed, since read access may be undesirable under certain
circumstances.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:
Nicklass, et al. Expires April 15, 2009 [Page 36]
Internet-Draft Manage ATM over PSN October 2008
The pwATMCfgTable, pwAtmPerfCurrentTable, pwAtmPerfIntervalTable and
pwAtmPerf1DayIntervalTable collectively show the ATM pseudo wire
connectivity topology and its performance characteristics.
If an Administrator does not want to reveal this information, then
these tables should be considered sensitive/vulnerable.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module, is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
11. IANA considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
pwATMMIB { mib-2 XXX }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXX" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
