RFC 3606 Supplemental ATM Managed Objects November 2003

1. 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].

2. Overview

The purpose of this memo is to provide additional capabilities, not
found in the ATM-MIB [RFC2515], which are needed to manage ATM
interfaces. This memo addresses the following areas:

- ATM Switch Support
- ATM Service Support
- ATM Host Support

In addition, this memo also provides ATM trap support.

2.1. Background

In addition to the MIB module defined in this memo, other MIB modules
are necessary to manage ATM interfaces, links and cross-connects.
Examples include MIB II for general system and interface management
([RFC2863]), the DS3 ([RFC2496]) or SONET MIBs ([RFC3592]) for
management of SONET and DS3 physical interfaces, and, as appropriate,
MIB modules for applications that make use of ATM, such as SMDS
[RFC1694] and LAN Emulation [ATM Forum LANE]. These MIB modules are
outside the scope of this specification.

This MIB module also requires the use of the ATM-MIB module defined
in [RFC2515] and ATM-specific textual conventions defined in
[RFC2514].

ATM Endpoint applications such as ATM LAN Emulation or Classical IP-
over-ATM Clients and Servers use ATM to establish SVC/PVC connections
for exchanging control and data information. The agents of these ATM
applications must provide the network manager with information on the
SVC/PVCs in use and which applications are using them. The
information can be made generic so as to apply to all ATM

Ly, et al. Standards Track [Page 3]

RFC 3606 Supplemental ATM Managed Objects November 2003

applications. This memo defines extensions to the ATM-MIB [RFC2515]
in order to support this.

The current specification of this supplemental ATM2-MIB is based on
SNMPv2 SMI.

2.2. Important Definitions

The following terms are defined here and used throughout this MIB:

- Virtual Path Link (VPL)
- Virtual Path Connection (VPC)
- Virtual Path Segment (VP Segment)
- Virtual Channel Link (VCL)
- Virtual Channel Connection (VCC)
- Virtual Channel Segment (VC Segment).

The figures on the next page show how these terms apply in typical
ATM network topologies. Additional terms relevant to this MIB are
defined and illustrated in the ATM Terminology section 3 of
[RFC2515].

Table 1: MIB structure

3.1.1. ATM SVC VP Cross-Connect Table

This table provides the SVC VP Cross-Connect (SVPC) information. The
equivalent PVC VP Cross-Connect table is defined in [RFC2515]. This
table also includes cross-connect information for Soft PVPs.

Ly, et al. Standards Track [Page 6]

RFC 3606 Supplemental ATM Managed Objects November 2003

This table contains configuration and state information of all SVC VP
point-to-point, point-to-multipoint, or multipoint-to-multipoint VP
cross-connects.

This table has read-only access and can be used to monitor the
cross-connects which connect the VPLs together in an ATM switch or
network. The atmSvcVpCrossConnectIndex is used to associate the
related SVC VPLs that are cross-connected together. The
atmSvcVpCrossConnectRowStatus object has read-write access to allow
for tear-down.

The ATM SVC VP Cross-Connect Table models each bi-directional
Switched Virtual Circuit (SVC) VP cross-connect as a set of entries
in the atmSvcVpCrossConnectTable. A point-to-point VPC cross-connect
is modeled as one entry; a point-to-multipoint (N leafs) VPC cross-
connect as N entries in this table; and a multipoint-to-multipoint (N
parties) VPC cross-connect as N(N-1)/2 entries in this table. In the
latter cases, all the N (or N(N-1)/2) entries are associated with a
single VPC cross-connect by having the same value of
atmSvcVpCrossConnectIndex.

_________________________________________

Low | ATM Switch or Network | High
port| | port
_____|>> from low to high VPC traffic flow >>|______
|<< from high to low VPC traffic flow <<|
|_______________________________________|

Figure 3: VPC Cross-Connect Model

The terms low and high are chosen to represent numerical ordering of
the two interfaces associated with a VPC cross-connect. That is, the
ATM interface with the lower value of ifIndex is termed 'low', while
the other ATM interface associated with the VPC cross-connect is
termed 'high'.

3.1.2. ATM SVC VC Cross-Connect Table

This table provides the SVC Cross-Connect (SVCC) information. The
equivalent PVC VC Cross-Connect table is defined in [RFC2515]. This
table also includes cross-connect information for Soft PVCs.

This table is used to model a bi-directional point-to-point, point-
to-multipoint or multipoint-to-multipoint SVC VC cross-connect.

Ly, et al. Standards Track [Page 7]

RFC 3606 Supplemental ATM Managed Objects November 2003

This table has read-only access and is used to monitor the cross-
connects which connect the VCLs together in an ATM switch or network
that belong to a VC connection. The atmSvcVcCrossConnectIndex is
used to associate the related SVC VCLs that are cross-connected
together. The atmSvcVcCrossConnectRowStatus object has read-write
access to allow for tear-down.

The ATM SVC VC Cross-Connect Table models each bi-directional
Switched Virtual Circuit (SVC) VC cross-connect as a set of entries
in the atmSvcVcCrossConnectTable. A point-to-point VC cross-connect
is modeled as one entry; a point-to-multipoint (N leafs) VC cross-
connect as N entries in this table; and a multipoint-to-multipoint (N
parties) VPC cross-connect as N(N-1)/2 entries in this table. In the
latter cases, all the N (or N(N-1)/2) entries are associated with a
single VPC cross-connect by having the same value of
atmSvcVcCrossConnectIndex.

|______________________________________|

Figure 4: VC Cross-Connect Model

The terms low and high are chosen to represent numerical ordering of
the two interfaces associated with a VPC cross-connect. That is, the
ATM interface with the lower value of ifIndex is termed 'low', while
the other ATM interface associated with the VPC cross-connect is
termed 'high'.

3.1.3. ATM Interface Signalling Statistics Table

This table provides statistical information of the signalling entity.
A signalling entity can be deployed over an ATM interface as defined
in the atmInterfaceConfTable [RFC2515], a logical ATM interface
defined in section 5.1.10.1 in this document, or a proprietary
virtual interface as described in the atmInterfaceExtTable. To
monitor the signalling entity, a few counters are provided. They are
defined as:

atmSigSSCOPConEvents
atmSigSSCOPErrdPdus
atmSigDetectSetupAttempts
atmSigEmitSetupAttempts
atmSigDetectUnavailRoutes

3.1.4. ATM Signalling Capability Support

A number of Information Elements may or may not be supported by ATM
switches or ATM Services. Hence, for trouble isolation it is
important to keep track which particular Information Elements are
supported. The corresponding group of objects must be supported by
switches or services supporting SVCs, and indicate whether the
following Information Elements are enabled/disabled:

1) Calling party number

2) Calling party subaddress

3) Called party subaddress

4) Broadband high layer information

5) Broadband low layer information

6) Broadband Repeat Indicator

7) AAL parameters

The last parameter, Preferred Carrier Pre-Subscription, identifies
the carrier to which intercarrier calls originated from this
interface are routed when transit network selection information is
not provided by the calling party.

Ly, et al. Standards Track [Page 9]

RFC 3606 Supplemental ATM Managed Objects November 2003

3.1.5. Signalling Descriptor Parameter Table

This table extends the ATM VCL table of the ATM-MIB [RFC2515] to
include all other necessary signalling information as specified in
the ATM Forum UNI Specifications [ATM Forum 3.0] and [ATM Forum UNI
3.1]. A user can create an entry with all signalling parameters and
later use that entry to specify the signalling characteristics of
SVCs.

Some of the signalling parameters, such as the AAL5 parameters
information element, are reflected in the VCL and VPL tables, and
this table only contains the remaining AAL5 parameters.

Signalling attributes can be grouped into following categories:

1) ATM Adaptation Layer Parameters

Information in this group is captured in the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer to
section 5.4.5.5 of [ATM Forum 3.0] and [ATM Forum UNI 3.1].

2) Broadband High Layer Information

Information in this group is captured by the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer to
section 5.4.5.8 of [ATM Forum 3.0] and [ATM Forum UNI 3.1].

3) Broadband Low Layer Information

Information in this group is captured by the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer to
section 5.4.5.9 of [ATM Forum 3.0] and [ATM Forum UNI 3.1].

3.1.6. ATM Interface Registered Address Table

This table contains a list of ATM addresses that can be used for
calls to and from a given interface by a switch or service. The ATM
addresses are either registered by the endsystem via ILMI or
statically configured. This table does not expose PNNI reachability
information. This table only applies to switches and network
services. See also Section 5.2.

Ly, et al. Standards Track [Page 10]

RFC 3606 Supplemental ATM Managed Objects November 2003

3.1.7. ATM VPI/VCI to Address Mapping Table

In the atmVclAddrTable, the object atmVclAddrAddr can either be an
ATM Local Address or an ATM Remote Address which represent the two
endpoint addresses of a VCL. ATM Local Address identifies the local
endpoint of the VCL represented by this agent. The ATM Remote
address represents the address of the ATM application at the other
end of the VCL.

3.1.8. ATM Address to VPI/VCI Mapping Table

This table provides an alternative way to retrieve the atmVclTable.
This table can be used to retrieve the indexing to the atmVclTable by
an ATM address.

3.1.9. ATM VPL Statistics Table

The atmVplStatTable includes per-VPL cell counters. The VPL cell
counters count the valid ATM cells. The valid ATM cells include the
user and OAM cells but exclude the physical layer (e.g., idle cells)
and unassigned cells. Cells coming into an ATM managed system are
counted differently with the high Cell Loss Priority (CLP=0) or low
Cell Loss Priority (CLP=1). The cells are tagged, passed or
discarded depending on the incoming CLP value and the policed cell
rate by the "traffic policing" entity in the ATM managed system.
Refer to [ATM Forum 3.0] and [ATM Forum UNI 3.1] for a description of
the traffic policing.

In the switch where the traffic policing is not supported, cells are
passed or discarded depending on the bandwidth and buffering capacity
of the switching fabric. The Output Tagged Cells counter, in this
case, is always zero.
_______________
| ATM Managed |
Input | System | Output

---------->| |----------->
CLP=1 cells| (traffic | CLP=1 cells
---------->| policing |----------->
| entity) | Tagged cells (CLP=1)
|_____________|----------->
|Discard | Discard

Figure 5: ATM Cell Counters per VPL

Ly, et al. Standards Track [Page 11]

RFC 3606 Supplemental ATM Managed Objects November 2003

In this table, cells coming into and out of the managed ATM system
are counted as the total number of cells and the cells with the
CLP=0. The CLP=1 counter is derived by subtracting CLP=0 cells from
the total cells. In addition, cells that are tagged on the output
are also counted. The output CLP=1 cells equals the total cells out
count minus both the CLP=0 cells and the tagged cells.

3.1.10. ATM VPL Logical Port Table

The ATM VPL Logical Port Table includes all ATM logical port
interface configuration information.

3.1.10.1. ATM Logical Port Interface

The interface type "ATM Logical Port" (ifType=80) is defined to allow
the representation of a VP Tunnel, which is a VPL used as a trunk
connection (most likely between devices that are not physically
adjacent), providing for multiplexing and demultiplexing of VCs on
the VP. Figure 6 illustrates such a VP Tunnel.

Note: the "ATM Logical Port" interface is more of a logical port,
compared with an interface of type "ATM" which is more of a physical
port that provides for the transport of many VP and VC connections
between adjacent devices.

<------VP Tunnel------>
ATM Switch A ATM Switch B
------------ -----------
|ATM |_____________|ATM |
|X-Connect | . |X-Connect |
VCL1 |Point | VPL1 . VPL2 |Point | VCL4
O---------|----X-----|----- . -----|----X-----|-----O
| X-----|----- . -----|----X |
| | |_____________| | |
------------ ------------
| VCL2 | VCL3
O O

Figure 6: Virtual Path Tunnel

In Figure 6, a VP tunnel (denoted as VPL1 by Switch A, and as VPL2 by
Switch B) is used to connect VCL1 with VCL4 and VCL2 with VCL3.
Figure 6 shows only one VP tunnel, but there can be multiple VP
tunnels over the same physical interface.

Ly, et al. Standards Track [Page 12]

RFC 3606 Supplemental ATM Managed Objects November 2003

A particularly useful VP tunnel scenario is tunneling across a public
network that does not support signalling. In Figure 6 above, assume
Switches A and B are private switches that signal over the VP to set
up connections transparently through the public network. The public
network would just transport a PVC VP between the two switches.

Because the VP Tunnel constitutes an interface between two ATM
devices that are not necessarily physically adjacent, most of the
management information pertaining to the interface may differ for the
tunnel, including:

- active VPI/VCI fields (the tunnel may be a subset of the parent
interface).
- maximum number of VCCs
- configured VCCs
- ILMI VPI/VCI values
- ATM address type
- ATM administrative address
- received/transmitted cells.

3.1.10.2. How to create an ATM Logical Port interface

On ATM devices supporting VP tunnels, the ATM Logical Port
Interface Table can be used to create VP tunnels. To create an
ATM Logical Port interface via SNMP:

- Create a VPL (e.g., VPI=a on an existing ATM interface
which has ifIndex=x) in the atmVplTable.

- Set the object atmVplLogicalPortDef to isLogicalIf.
A new row in the ifTable is then created by the agent,
with ifIndex=y, to represent the ATM Logical Port
interface. The object atmVplLogicalPortIndex is also
set to y by the agent to represent the ifIndex value of
the ATM Logical Port interface.

- The ifEntry values are set for the ATM Logical
Port interface (ifIndex=y) as discussed in RFC
2515, with the following exceptions:
* ifType - a new enumerated value of atmLogical(80)
was added to IANAifType, specifying an "ATM
Logical Port" interface.
* ifSpeed - The total bandwidth in bits per
second for use by the ATM layer. Computed
from the traffic descriptor for the VPL.

Ly, et al. Standards Track [Page 13]

RFC 3606 Supplemental ATM Managed Objects November 2003

* ifOperStatus - determined hierarchically,
depending on the state of the physical
atm-cell layer interface beneath it,
and the ILMI on the VP.
* ifInOctets, ifOutOctets - support of
these objects is not mandatory for ATM
Logical Port interfaces.
* ifInErrors - always zero, HEC errors are
specified for the atm cell-layer interface
beneath it.
* ifInUnknownProtos - always zero, errors
are specified for the atm cell-layer
interface beneath it.

- The atmInterfaceConfEntry values are set and reported
as discussed in [RFC2515], with the following exceptions:
* atmInterfaceMaxVpcs - 0.
* atmInterfaceConfVpcs - 0.
* atmInterfaceIlmiVpi - VPI of the VP tunnel.

- The atmInterfaceExtEntry values are set and reported
as follows:
* atmInterfaceConfMaxSvpcVpi - VPI of the VP tunnel,
although VPCs cannot be setup on a VP tunnel.
* atmInterfaceCurrentMaxSvpcVpi - VPI of VP tunnel,
although VPCs cannot be setup on a VP tunnel.
* atmInterfaceConfMaxSvccVpi - VPI of the VP tunnel.
* atmInterfaceCurrentMaxSvccVpi - VPI of VP tunnel.
* atmIntfPvcFailures - Includes failures of PVCLs
within the VP tunnel, but not of the PVPL itself,
since those are reported on the atm(37) interface.
* atmIntfCurrentlyFailingPVpls - 0.
* atmIntfPvcFailuresTrapEnable - Enables traps for
PVCL failures within the VP tunnel, but not for
the PVPL itself, since the latter are generated on
behalf of the atm(37) interface.

- An entry is created in the ifStackTable, with
values: ifStackHigherLayer=y, ifStackLowerLayer=x.

- VCLs defined on the VP tunnel are indexed by
ifIndex=y, VPI=a, VCI.

Ly, et al. Standards Track [Page 14]

RFC 3606 Supplemental ATM Managed Objects November 2003

3.1.11. ATM VCL Statistics Table

The atmVclStatTable includes per-VCL cell counters. The VCL cell
counters count the valid ATM cells. The valid ATM cells include
the user and OAM cells but exclude the physical layer (e.g., idle
cells) and unassigned cells. Cells coming into an ATM managed
system are counted differently with the high Cell Loss Priority
(CLP=0) or low Cell Loss Priority (CLP=1). The cells are tagged,
passed or discarded depending on the incoming CLP value and the
policed cell rate by the "traffic policing" entity in the ATM
managed system. Refer to [ATM Forum 3.0] and [ATM Forum UNI 3.1]
for the description of the traffic policing.

In a switch where the traffic policing is not supported, cells are
passed or discarded depending on the bandwidth and buffering
capacity of the switching fabric. The Output Tagged Cells
counter, in this case, is always zero.

_______________
| ATM Managed |
Input | System | Output
CLP=0 cells| | CLP=0 cells
---------->| |----------->
CLP=1 cells| (traffic | CLP=1 cells
---------->| policing |----------->
| entity) | Tagged cells (CLP=1)

V V

Figure 7: ATM Cell Counters per VCL

In this table, cells coming into and out of the managed ATM system
are counted as the total number of cells and the cells with the
CLP=0. The CLP=1 counter is derived by subtracting CLP=0 cells from
the total cells. In addition, cells that are tagged on the output
are also counted. The output CLP=1 cells equals the total cells out
count minus both the CLP=0 cells and the tagged cells.

3.1.12. ATM VC General Information Table

This table contains the general information for each VC. It provides
an index to the atmSigDescrParamTable defined in this MIB. This
table is an extension to the atmVclTable defined in the ATM-MIB
[RFC2515].

Ly, et al. Standards Track [Page 15]

RFC 3606 Supplemental ATM Managed Objects November 2003

3.1.13. ATM Interface Configuration Extension Table

The ATM Interface Configuration Extension Table contains ATM
interface information that supplements the atmInterfaceConfTable
defined in [RFC2515]. It includes the configuration information of
the interface type (i.e., connection setup procedures) and ILMI.

A network manager can configure the interface to run a specific type
of connection setup procedures (i.e., protocol and version) such as
ITU-T DSS2, ATM Forum UNI 3.1, PNNI 1.0 or BICI 2.0. It can also
dictate the role of the managed entity as one side of the interface.
For example, if an interface is configured to run ATM Forum UNI 3.1,
the managed entity has to be told to run as either the network side
or the user side of the UNI.

The objects atmIntfConfigType and atmIntfConfigSide are used for
configuration and the objects atmIntfActualType and atmIntfActualSide
are used for reading back the actual interface protocol and version.

The following table describes all the valid combinations of
configuration of the interface type and side. Note that the value
N/A meaning not applicable, should be set to the value other(1) when
used.

atmIntfConfigType atmIntfConfigSide
----------------- -----------------
autoConfig N/A
ituDss2 user/network
atmfUni3Dot0 user/network
atmfUni3Dot1 user/network
atmfUni4Dot0 user/network
atmfIispUni3Dot0 user/network
atmfIispUni3Dot1 user/network
atmfIispUni4Dot0 user/network
atmfPnni1Dot0 N/A
atmfBici2Dot0 N/A
atmfUniPvcOnly user/network
atmfNniPvcOnly N/A

When the value of the object atmIntfConfigType is configured to
autoConfig(2), the interface type is determined via the ATM Forum
ILMI auto-configuration procedures [ATM Forum ILMI]. There is no
need to set the interface side since it should be a derived value.
The PNNI and BICI interfaces are always symmetric so setting the
interface side is also not necessary.

Ly, et al. Standards Track [Page 16]

RFC 3606 Supplemental ATM Managed Objects November 2003

This table also includes the configured and negotiated maximum VPI
value per ATM interface, and the configured and negotiated minimum
VCI value per ATM interface. Refer to [ATM Forum ILMI] Sections
8.2.3.8 through 8.2.3.10 for a detailed description.

The following figure provides an example how the current minimum VCI
values are derived from the configured minimum VCI values and the
neighboring minimum VCI values:

+--------+ +--------+ +--------+
| ATM | ifA ifB | ATM | ifC ifD | ATM |
| Device |--------------| Device |--------------| Device |
+--------+ +--------+ +--------+

ifA: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 40 (negotiated)

ifB: Configured Min SVCC VCI = 40 (configured)
Current Min SVCC VCI = 40 (negotiated)

ifC: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 32 (negotiated)

ifD: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 32 (negotiated)

Between ifA and ifB, the maximum of the two vales for
atmInterfaceConfMinSvccVci is 40, so both interfaces set their
atmInterfaceCurrentMinSvccVci values to 40. On the other hand, since
ifC and ifD both are configured with atmInterfaceConfMinSvccVci
values of 32, they set their atmInterfaceCurrentMinSvccVci values to
32.

3.1.14. ATM ILMI Service Registry Table

This table contains information used by the switch/service to inform
ATM hosts of the location of ATM network services such as the LAN
Emulation Configuration Server (LECS), the ATM Name Server (ANS), the
ATMARP Server, the Multicast Address Resolution Server (MARS), and
the NHRP Server (NHS). Entries in this table are exported to
adjacent devices via ILMI over either all or a few user selected ATM
interfaces.

Ly, et al. Standards Track [Page 17]

RFC 3606 Supplemental ATM Managed Objects November 2003

As an example, let's assume that:

- An ATM switch X has three interfaces if1, if2 and if3.
- There are two ATM network services offered, a1.a2...aN and
b1.b2...bN, where a1.a2...aN is an object identifier used to
identify the first service, and b1.b2...bN is the object
identifier for the other service.
- The first service is available at the ATM address 'a'.
- The second service is available at the ATM address 'b'.
- The first service can be used by any device connecting to the
switch X.
- The second service can be used only by devices that connect to
interfaces if1 and if3 on switch X.

+------------------+ +------------------+
|service a1.a2...aN| |service b1.b2...bN|
| | | |
| ATM address = a | | ATM address = b |
+--------+---------+ +--------+---------+
| |
| |
+--------+-----------------------+---------+
| ATM NETWORK |
+-----------------+------------------------+
|
|
+-------------+
| switch X |
+-+----+----+-+
| | |
| | |
if1 if2 if3 (interfaces)

Figure 9: ATM topology with registered services

The table for switch X will contain three entries:

- one entry for the "a1.a2...aN", implicitly available to any
devices on switch X.
- two entries for the "b1.b2...bN" (one for each interface
where this service can be explicitly used).

Ly, et al. Standards Track [Page 18]

RFC 3606 Supplemental ATM Managed Objects November 2003

The content of the table is:

- Service Identifier: a1.a2...aN b1.b2...bN b1.b2...bN
- ATM address: a b b
- Arbitrary index: m n p
- Available interface: 0 1 3

where the Service Identifier values a1.a2...aN and b1.b2...bN are
represented by atmIlmiSrvcRegServiceID, the ATM addresses a and b are
represented by atmIlmiSrvcRegATMAddress, the values m, n, and p are
arbitrary non-zero integer parameters (necessary in this example to
differentiate the two entries for b1.b2...bN that are both available
at the ATM address 'b') represented by atmIlmiSrvcRegAddressIndex,
and the available interfaces are represented by atmIlmiSrvcRegIndex,
where the special value 0 indicates any ATM interface.

When querying the ILMI service registry table, through the ILMI
protocol:

- the device attached to interface if1 will obtain the address a and
b.

- the device attached to interface if2 will obtain the address a
only.

- the device attached to interface if3 will obtain the address a and
b.

3.1.15. ILMI Network Prefix Table

A table specifying per-interface network prefix(es) supplied by the
network side of the UNI during ILMI address registration. When no
network prefixes are specified for a particular interface, one or
more network prefixes based on the switch address(es) may be used for
ILMI address registration.

3.1.16. ATM Switch Address Table

This table contains one or more ATM endsystem addresses on a per-
switch basis. These addresses are used to identify the switch. When
no ILMI network prefixes are configured for certain interfaces,
network prefixes based on the switch address(es) may be used for ILMI
address registration.

3.1.17. AAL5 per-VCC Statistics Table

This table contains the AAL5 statistics for the VCCs.

Ly, et al. Standards Track [Page 19]

RFC 3606 Supplemental ATM Managed Objects November 2003

3.1.18. ATM VP Cross-Connect Extension Table

This table extends the atmVpCrossConnectTable defined in ATM-MIB
[RFC2515].

3.1.19. ATM VC Cross-Connect Extension Table

This table extends the atmVcCrossConnectTable defined in ATM-MIB
[RFC2515].

3.1.20. Currently Failing PVPL Table

This table contains all the PVPLs that are in trouble.

3.1.21. Currently Failing PVCL Table

This table contains all the PVCLs that are in trouble.

3.1.22. Leaf Initiated Join Counter support

Two counter objects are added to count the number of leaf intiated
setup requests and setup failures.

3.2. Network and User Addresses

At the user side of a given ATM UNI interface there may be an
address, "ifPhysAddress", to identify the interface. In addition,
there may be several other addresses which can be used to originate
and receive calls. These other addresses that are used to receive
calls are listed in the "ifRcvAddrTable" defined in RFC 2863. The
registered addresses on the network side are listed in the ATM
Registered Address Table. The ATM Registered Address Table is
supported by switches and network services. It is not supported by
hosts.

3.3. Configuration of VPLs, VCLs, and Cross-Connects

The ATM Managed Objects needed to support the configuration of VPLs,
VCLs, and Cross-Connects of the Permanent VPLs and VCLs are defined
in the ATM-MIB [RFC2515]. Cross-Connects of the Switched VPLs and
VCLs are defined in this memo.

3.4. ATM-related Trap Support

Traps are defined to detect changes in the status of permanent VPLs
and VCLs. The current up/down status of each permanent VPL or VCL is
indicated by the atmVplOperStatus or atmVclOperStatus object,
respectively. Several tables and objects and one trap are defined in

Ly, et al. Standards Track [Page 20]

RFC 3606 Supplemental ATM Managed Objects November 2003

order to help network managers quickly and efficiently detect changes
in the status of permanent virtual links. Through use of these
tables, objects, and traps, the time consuming and resource intensive
task of continuously polling each row in the entire atmVplTable and
atmVclTable can be avoided.

The atmIntfPvcFailures counter and the atmIntfCurrentlyFailingPVpls
and atmIntfCurrentlyFailingPVcls gauges provide a quick means of
determining the status of all PVPLs and PVCLs on an interface. The
atmCurrentlyFailingPVplTable and the atmCurrentlyFailingPVclTable
list all of the problematic PVPLs and PVCLs, respectively, allowing
them to be quickly identified.

The atmIntfPvcFailuresTrap is generated just after a PVPL or PVCL on
a particular interface leaves the 'up' operational state. Managers
can then determine which PVPLs and/or PVCLs are failing by reading
the atmCurrentlyFailingPVplTable and the
atmCurrentlyFailingPVclTable. Generation of the
atmIntfPvcFailuresTrap is rate limited by suppressing all traps that
would occur within atmIntfPvcNotificationInterval of a previous trap
for the same interface. Managers should continuously poll the tables
and objects mentioned above for at least this amount of time in order
to keep up with the state of the network.

8. 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:

12. atmAal5VclStatTable AAL5 statistics (read-only)
13. atmVclGenTable Signalling configuration
14. atmInterfaceExtTable Interface configuration
15. atmIlmiSrvcRegTable ILMI config params
16. atmIlmiNetworkPrefixTable ILMI config params
17. atmSwitchAddressTable Switch address info

19. atmVcCrossConnectXTable VC cross-connect params
20. atmCurrentlyFailingPVplTable PVPL status info (read-only)
21. atmCurrentlyFailingPVclTable PVCL status info (read-only)

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.

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

RFC 3606 Supplemental ATM Managed Objects November 2003

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.
