draft Supplemental ATM Management Objects March 1995
2. Introduction
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management
protocols in the Internet community. In particular, it
describes objects used for managing ATM-based interfaces,
devices, networks and services in addition to those defined in
the ATM MIB [1], to provide additional support for the
management of:
- ATM Switched Virtual Connections (SVCs)
- ATM Permanent Virtual Connections (PVCs)
This memo specifies a MIB module in a manner that is both
compliant to the SNMPv2 SMI, and semantically identical to the
peer SNMPv1 definitions.
This memo does not specify a standard for the Internet
community.
3. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
0 RFC 1442 [2] which defines the SMI, the mechanisms used
for describing and naming objects for the purpose of
management.
0 STD 17, RFC 1213 [3] defines MIB-II, the core set of
managed objects for the Internet suite of protocols.
0 RFC 1445 [4] which defines the administrative and other
architectural aspects of the framework.
0 RFC 1448 [5] which defines the protocol used for network
access to managed objects.
The Framework permits new objects to be defined for the
purpose of experimentation and evaluation.

4. Object Definitions
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. Objects in the
MIB are defined using the subset of Abstract Syntax Notation
One (ASN.1) defined in the SMI. In particular, each object
type is named by an OBJECT IDENTIFIER, an administratively
assigned name. The object type together with an object
instance serves to uniquely identify a specific instantiation
of the object. For human convenience, we often use a textual
string, termed the descriptor, to also refer to the object
type.
5. Overview
The purpose of this memo is to provide additional
capabilities, not found in the ATM MIB [1], which are needed
to manage ATM interfaces. This memo addresses the following
areas:
- ATM Switch/Network/Host Support
- ATM Switch/Network Support
- ATM Host Support
5.1. 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 (RFC 1213 and RFC 1573), the DS3 or
SONET MIBs for management of SONET and DS3 physical
interfaces, and, as appropriate, MIB modules for applications
that make use of ATM, such as SMDS [15] and LAN Emulation
[14]. These MIB modules are outside the scope of this
specification.
This MIB module also requires the use of the ATM MIB module
defined in [1].
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
Expires XX [Page 3]
draft Supplemental ATM Management Objects March 1995
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 applications. This
memo proposes extensions to the ATM MIB [1] in order to
support this.
The current specification of this supplemental ATM MIB is
based on SNMPv2.
5.2. Supported Functions
The managed ATM objects are arranged into the following
groups:
- ATM Switch/Network/Host Support:
(1) ATM Switch/Network/Host Group
(2) ATM Switch/Network/Host SVC Group
- ATM Switch/Network Support:
(3) ATM Switch/Network Group
(4) ATM Switch/Network SVC Group
- ATM Host Support:
(5) ATM Host Group
(6) ATM Host SVC Group
5.2.1. ATM Switch/Network/Host Support
5.2.1.1. ATM Switch/Network/Host Group
5.2.1.1.1. ATM VCL Statistics Table
The atmVclStatTable is an extension to the atmVclTable. It
contains counters such as the cells received and cells
transmitted per SVC or PVC. These counters are defined as 32
bit integers. The implementation of this table is optional.
5.2.1.2. ATM Switch/Network/Host SVC Group
5.2.1.2.1. ATM Interface SVC Configuration Table
This group contains information on the configuration of local
ATM interfaces on an ATM device required to support SVCs in
addition to those defined in the atmInterfaceConfTable of the
ATM MIB [1] and those defined in RFC1573 [6].
Expires XX [Page 4]
draft Supplemental ATM Management Objects March 1995
Two important aspects of a local ATM interface that supports
SVCs are the peak bandwidth assigned to the signalling virtual
channel and signalling type used. The signalling virtual
channel is a point-to-point, bidirectional symmetric, virtual
channel connection. The range of peak bandwidth values is 173
cells/sec to 3979 cells/sec, in steps of 173 cells/sec, with a
default value of 173 cells/sec. Using the ATM MIB [1] the
signalling virtual channel bandwidth is assigned by creating a
row in the ATM Traffic Descriptor Table which defines a Peak
Cell Rate (PCR) which represents the signalling channel
bandwidth. Then using an entry in the atmVclTable [1],
identify this row in the ATM Traffic Descriptor Table as the
traffic descriptor for the signalling channel bandwidth.
The signalling type defines the type of signalling supported
at the local ATM interface (e.g., Q.2931 signalling). The
defined signalling types supported by this MIB include: Q.2931
[11], ATM Forum's UNI 3.1 [10], and ATM Forum's P-NNI [12].
This group contains a set of timers that do not have universal
default values. The following timers are supported by either
Q.2931 [11], ATM Forum UNI 3.1 [10], or both:
T302 Overlap Sending Timer:
Applicable to both Hosts and Network Switches. This
timer starts when a SETUP ACKNOWLEDGE message is sent.
The normal cause for stopping is when sending a complete
indication, or network alert or connect request received.
At first expiry clear if call information determined to
be definitely incomplete; else send a CALL PROCEEDING.
The range of this timer is defined in Q.2931 as 10-15
seconds. T302 is a Mandatory timer only if Q.2931
Section 6.5 "Overlap Sending and Receiving" is
implemented. Note: The ATM Forum UNI 3.1 [10] does not
support this timer.
T310 Outgoing Call Proceeding Timer:
Applicable to both Hosts and Network Switches. This
timer starts when a CALL PROCEEDING message is received.
The normal cause for stopping is when an ALERT, CONNECT,
or RELEASE message is received. At first expiry a
RELEASE message is sent. The range of this timer from 10
to 120 seconds. T310 is a Mandatory timer. Q.2931
recommends a default value of 30-120 seconds and the ATM
Forums UNI 3.1 Specification recommends a default value
Expires XX [Page 5]
draft Supplemental ATM Management Objects March 1995
of 10 seconds. Therefore, the range is between 10-120
seconds.
T317 Restart Timer:
Applicable to both Hosts and Network Switches. This
timer starts when a RESTART message is received. The
normal cause for stopping this timer is when there is an
internal clearing of call references. At first expiry
there is a maintenance notification. T317 is a Mandatory
timer. The range of this timer is less than the value of
Timer T316 (i.e., less than 2 minutes).
In addition to above timers, several other timers which are
used by hosts and network switches are defined by either
Q.2931, ATM Forum UNI 3.1, or both of them. However, these
timers have not been defined as managed objects since
recommended default values can be used. The timers not
defined in this MIB fit into one of the following categories:
1) If the Timer is only supported by the ATM Forum
UNI 3.1, then use the ATM Forum UNI 3.1
Recommended default value for the timer.
2) If the Timer is only supported by Q.2931, then
use the Q.2931 Recommended default value for
the timer.
3) If the Timer is supported by ATM Forum UNI 3.1
and Q.2931, then use the common default value
for the timer.
The following timers are not included in this MIB: T301, T303,
T304, T306, T308, T309, T313, T316, T322, T398, T399.
5.2.1.2.2. SSCOP Table
This group contains information on the ATM SSCOP signalling
layer and must be supported by signalling entities.
5.2.1.2.3. Unsupported Service Failures Table
This group contains information on the setup failures that
occur when setting up an ATM SVC. Maintaining counters for
each individual signalling cause codes would result in a large
number of counters. Instead, this memo uses an approach that
lumps events into three categories. Three counters are used
Expires XX [Page 6]
draft Supplemental ATM Management Objects March 1995
to monitor connection failures occurring due to: 1)
unavailable route, 2) unavailable switch or network
resources, or 3) the called party. The counters are defined
as follows:
1. Route Unavailable Counter
This counter maintains the number of
calls cleared because there was no
route unavailable to the destination.
2. Resources Unavailable Counter
This counter maintains the number of cleared
calls due to switch or network resources being
unavailable.
3. Called Party Counter
This counter maintains the number of cleared
calls caused by the called party (e.g.,
called party rejects the call).
5.2.1.2.4. ATM Signalling Layer Protocol Errors Table
This group contains information on the Protocol Errors that
occur at the signalling layer when establishing an ATM SVC.
5.2.1.2.5. UNI Signalling Sub-layer Statistics Table
Configuration is needed per signalling entity in order to
manage attributes of all SVCs set up by that entity.
Signalling entities are not always bound one to one to ATM
UNIs which is not always the case: a more flexible indexing
mechanism would be to multiple signalling entities on a single
UNI or vice versa - using ifIndex and VPI would provide
sufficient flexibility here.
Statistics per VCL are needed in order to find out the usage
of VCL resources by ATM applications. Additionally, to
monitor the usage and health of an UNI signalling entity, some
counters are needed per UNI signalling entity. Two new
objects are added to count the number of connections
established. One for incoming SVCs and one for outgoing SVCs.
Expires XX [Page 7]
draft Supplemental ATM Management Objects March 1995
5.2.2. ATM Switch/Network Support
5.2.2.1. ATM Switch/Network Group
5.2.2.1.1. ATM Interface Administrative Address Table
This group is only supported by switches or networks for
interfaces that have multiple associated addresses. This
group contains an ATM Interface Administrative Address Table
(atmIfAdminAddrTable) which list up to 16 valid addresses for
calls to and from a given interface. One of these numbers
shall be specified as the "default" number. With screening,
the Calling Party Number Information Element received in the
SETUP message is checked by the switch or network to verify
that it is one of the allowable addresses listed in the
atmIfAdminAddrTable.
5.2.2.2. ATM Switch/Network SVC Group
5.2.2.2.1. ATM UNI SVC Subscription Features Table
This group must be supported by switches or networks
supporting SVCs. The following subscription features for a
UNI that supports ATM SVCs are contained in this group:
1) Calling party number delivery feature
This parameter indicates whether the calling party number is
delivered by the switch or network to the called address.
(The calling party number is always delivered by the switch or
network to the terminating switch, and this feature determines
whether the number is delivered to the called party.) The
default value is 'disabled' which indicates that the feature
is not active.
2) Calling party number screening feature
This parameter indicates whether screening of a calling party
number is supported by the switch or network. If supported,
the switch or network checks the calling party number received
in the SETUP or ADD PARTY message to verify that it is one of
the allowable calling party numbers. (This list of allowable
calling party numbers is located in the atmIfAdminAddrTable
with up to 16 valid addresses per UNI. One of these numbers
shall be specified as the "default" number.)
Expires XX [Page 8]
draft Supplemental ATM Management Objects March 1995
If the received calling party number fails screening, the
switch or network will replace the calling party number
received in the SETUP or ADD PARTY message with the default
number for the interface before forwarding this to the called
party. This will result in a completed call, but the
delivered calling party number will not be the number
indicated by the calling party. Failed screening number
events are monitored by the atmSubscrFeaturClgPtyFailScrCnts.
The default value for this feature is 'enabled' which
indicates that the screening is active.
3) Calling party subaddress transfer feature
This parameter indicates whether the switch or network
accepts, transfers, and delivers the Calling Party Subaddress
Information Element received in the appropriate signalling
message. The default value is 'disabled' which indicates that
the feature is not active.
4) Called party subaddress transfer feature
This parameter indicates whether the switch or network
accepts, transfers, and delivers the Called Party Subaddress
Information Element received in the appropriate signalling
message. The default value is 'disabled' which indicates that
the feature is not active.
5) High layer information transfer feature
This parameter indicates whether the switch or network
accepts, transfers, and delivers the Broadband High Layer
Information Element received in the appropriate signalling
message. The default value is 'disabled' which indicates that
the feature is not active.
6) Low layer information transfer feature
This parameter indicates whether the switch or network
accepts, transfers, and delivers Broadband Low Layer
Information Element received in the appropriate signalling
message. The default value is 'disabled' which indicates that
the feature is not active.
7) Low layer information selection feature
Expires XX [Page 9]
draft Supplemental ATM Management Objects March 1995
This parameter indicates whether the switch or network
accepts, transfers, and delivers up to three instances of the
Broadband Low Layer Information Element for low layer
information selection received in the appropriate signalling
message. The default value is 'disabled' which indicates that
the feature is not active. This parameter may be supplied
only if the Low layer information transfer feature has a value
of 'enabled'.
8) AAL parameter information transfer feature
This parameter indicates whether the switch or network
accepts, transfers, and delivers the ATM Adaptation Layer
Parameters Information Element received in the appropriate
signalling message. The default value is 'disabled' which
indicates that the feature is not active.
9) Preferred Carrier Presubscription
This parameter 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.
5.2.3. ATM Host Support
5.2.3.1. ATM Host Group
5.2.3.1.1. VCL Extension Table
There can be two types of VCLs, Permanent VC or Switched VC
used by ATM applications. The ATM MIB [1] provides general
connection management (atmVclTable). This memo provides an
extension to the atmVclTable which supports both SVC/PVC
monitoring and PVC configuration capabilities.
This table contains information needed for configuring PVCs
and monitoring SVC/PVCs. It is an extension to the atmVclTable
defined in the ATM MIB [1].
The object Remote ATM address and Local ATM address describe
the two endpoint addresses of a VCL. Local ATM address
represents the ATM endpoint at the end of the VCL represented
by this agent. Remote ATM address represents the ATM
application at the other end.
Expires XX [Page 10]
draft Supplemental ATM Management Objects March 1995
The object Connection Type is the type of the VCL, it is
either a PVC, an incoming SVC or a outgoing SVC. When
creating an SVC, the agent can represent the VCL's attributes
by selecting entries from two tables: the ATM Traffic
Descriptor Parameter Table defined in the ATM MIB [1] and the
ATM Signalling Descriptor Parameter Table defined in this
memo. For SVCs, the Signalling Descriptor index is used to
point to an entry in the ATM Signalling Descriptor Parameter
Table.
5.2.3.1.2. ATM Addresses to VCC Mapping Table
Some ATM applications (e.g. LAN Emulation) use ATM endpoint
addresses even over PVCs. In order to trace SVC/PVCs between
such ATM applications, it is important to be able to monitor
VCLs (both SVCs and PVCs) indexed by their endpoint ATM
addresses. The atmVclAddrTable contains all VCCs currently
active and is indexed by the remote ATM address. It is used in
conjunction with the atmVclTable and the atmVclExtTable. Each
entry in this table identifies an entry in the
atmVclTable/atmVclExtTable.
5.2.3.2. ATM Host SVC Group
5.2.3.2.1. Signalling Parameter Descriptor Table
This table extends the ATM VCL table of the ATM MIB [1] to
include all other necessary signalling information as
specified in both ATM Forum UNI Specifications [9] and [10].
A user can create an entry with all signalling parameters and
later use that entry to specify the signalling characteristics
of SVCs.
Signalling attributes can be grouped into following
categories:
1) ATM Adaptation Layer Parameters
Information in this group are captured in the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer
to section 5.4.5.5 of [9] and [10].
2) Broadband Bearer Capability
Expires XX [Page 11]
draft Supplemental ATM Management Objects March 1995
Information in this group are captured by the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer
to section 5.4.5.7 of [9] and [10].
3) Broadband High Layer Information
Information in this group are captured by the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer
to section 5.4.5.8 of [9] and [10].
4) Broadband Low Layer Information
Information in this group are captured by the ATM Signalling
Descriptor Parameter Table defined in this memo. Please refer
to section 5.4.5.9 of [9] and [10].
6. Valid Address Sets / Default Address
A given ATM UNI interface may have an Address,
"ifPhysAddress", to identify the interface. In addition, a
given ATM UNI interface may have several other valid
addresses which can be used to originate and receive calls.
The valid addresses that are used to receive calls are listed
in the "ifRcvAddrTable" defined in RFC1573 [6]. ATM
interfaces of switches and networks do not use the
ifRcvAddrTable. Valid addresses to be used by a switch or
network are listed in the ATM Interface Administrative Address
Table. The ATM Interface Administrative Address Table is not
supported by hosts.
7. Configuration of VPLs, VCLs, and Cross-Connects
The ATM Managed Objects needed to support the configuration of
VPLs, VCLs, and Cross-Connects are defined in the ATM MIB [1].
