_1. _S_t_a_t_u_s _o_f _t_h_i_s _M_e_m_o
This document is an Internet Draft. Internet Drafts are
working documents of the Internet Engineering Task Force
(IETF), its Areas, and its Working Groups. Note that other
groups may also distribute working documents as Internet
Drafts.
Internet Drafts are valid for a maximum of six months and may
be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet Drafts as reference
material or to cite them other than as a "work in progress".

_2. _I_n_t_r_o_d_u_c_t_i_o_n
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. _T_h_e _S_N_M_P_v_2 _N_e_t_w_o_r_k _M_a_n_a_g_e_m_e_n_t _F_r_a_m_e_w_o_r_k
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. _O_b_j_e_c_t _D_e_f_i_n_i_t_i_o_n_s
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. _O_v_e_r_v_i_e_w
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 Support
- ATM Service Support
- ATM Host Support
_5._1. _B_a_c_k_g_r_o_u_n_d
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
the network manager with information on the SVC/PVCs in use
Expires in six months [Page 3]
draft Supplemental ATM Management Objects Sept 1996
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 SMI.
_5._2. _I_m_p_o_r_t_a_n_t _D_e_f_i_n_i_t_i_o_n_s
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 atmSigTable is indexed by the ifIndex, which can be of
type ATM (ifType=80), ATM logical port (ifType=80) or
proprietary virtual interface (ifType=proprietary). The ATM
logical port represents the interface of a VP tunnel, and each
such interface may have zero or one signalling VCLs. An ATM
switch often switch cells over an internal interface (a
proprietary virtual interface), to and from an ATM application
resides in the ATM switch. If such an interface has a
signalling VCL, the atmSigTable must includes a row for the
interface.

Figure 4 gives an example of the signalling VCLs and their
associated interfaces for an ATM switch. The cross-connecting
of the signalling channels is done to allow the reading of
AAL5 errors.

Figure 4: Model of ATM Switch's Signalling Channels
and Associated Interfaces
In Figure 4 there are two physical interfaces, with ATM-layers
depicted as IF1 and IF3. IF2 is the "ATM Logical Port"
interface provided by the VP tunnel with VPI=44 on the
physical interface. IF4 and IF5 are the ATM and AAL5
(respectively) internal sub-layer interfaces for VCLs
terminating at the switch. It is assumed in this example that
the ifIndex value for IF1 is 1, IF2 is 2, etc. There are 4
rows in the atmSigTable, therefore, indexed by their ifIndex
Expires in six months [Page 9]
draft Supplemental ATM Management Objects Sept 1996
values 1, 2, 3 and 4.
In the case depicted:
- On IF1, the VCL1 signalling channel can be used to set
up connections over the interface address space with
the exception of the VP with VPI=44. An entry exists
in the atmVplTable with index ifIndex=1,atmVplVpi=44,
and in the augmenting atmVplLogIfConfTable,
atmVplLogIfDef=isLogicalIf(2), atmVplLogIfIndex=2.
- On IF2, the VCL2 Signalling channel can set up VCs
over the ATM Logical Port interface's address space
(VPI=44, VCI range dictated by configuration).
- On IF3, the VCL3 signalling channel can be used to set
up VCs over the entire interface address space.

draft Supplemental ATM Management Objects Sept 1996
The only VCLs depicted in the Figure 4 are those used for
Signalling. External interface VCLs are cross-connected to
VCLs at the proprietary interface. The rows show up in the ATM
VCL table are:
ifIndex, atmVclVpi, atmVclVci
=============================
VCL1 1 0 5
VCL2 2 44 5
VCL3 3 0 5
VCL4 4 p1 c1
VCL5 4 p2 c2
VCL6 4 p3 c3
The p(i) and c(j) values for VPI/VCI on the VCLs on the
proprietary interface indicate that these values are chosen by
the switch software (versus the values dictated on the
external interfaces).
_5._3._3._1. _A_T_M _I_n_t_e_r_f_a_c_e _S_i_g_n_a_l_l_i_n_g _C_o_n_f_i_g_u_r_a_t_i_o_n _I_n_f_o_r_m_a_t_i_o_n
A manager can configure the Signalling entity to run a
specific signalling suit such as DSS2, ATM Forum UNI, PNNI or
BICI. It can also dictate the side of the signalling. For
example, if a signalling entity is configured to run ATM Forum
UNI 3.1, it has to be told to run as the network side or the
user side of the UNI.
The objects atmSigConfigSigType and atmSigConfigSide are used
for configuration and the objects atmSigActiveSigType and
atmSigActiveSigSide are used for reading back the actual
signalling configuration.
The following table describes all the combinations of the
configuration of the signalling entity:
atmSigConfigSigType atmSigConfigSigSide
---------------- ----------------

Expires in six months [Page 11]

atmfPnni1Dot0 other
atmfBici2Dot0 other
When the value of the object atmSigConfigSigType is configured
to autoConfig(2), the signalling type is determined via the
ATM Forum ILMI auto-configuration procedures [22]. There is
no need to set the signalling side since it should be a
derived value. The PNNI and BICI interfaces are always
symmetric so setting the signalling side is also not
necessary.
_5._3._3._2. _S_i_g_n_a_l_l_i_n_g _M_o_n_i_t_o_r_i_n_g _I_n_f_o_r_m_a_t_i_o_n
To monitor the signalling entity, a few counters are provided.
They are defined as:
_5._3._3._2._1. _S_S_C_O_P _C_o_u_n_t_e_r_s
This group contains information on the ATM SSCOP signalling
layer and must be supported by signalling entities.
_5._3._3._2._2. _U_n_s_u_p_p_o_r_t_e_d _S_e_r_v_i_c_e _F_a_i_l_u_r_e_s
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 the following categories:
- Route Unavailability Counter
- Resources Unavailability Counter
- Called Party Events Counter
- Message Error Counter
- Calling Party Events Counter
- Timer Expiries Counter
- Restart Activity Counter
In addition, a Setup Attempts Counter was added to keep track
of the number of Setup attempts made (both successful and
unsuccessful).
Setup attempts are counted both at the receiving and sending
sides of the signalling entity. For example, the object
atmSigDetectSetupAttempts counts the number of setup attempts
Expires in six months [Page 12]
draft Supplemental ATM Management Objects Sept 1996
detected on the interface and the object
atmSigEmittSetupAttempts counts the number of setup attempts
emitted from this interface. Thus, a switch will increment
both the receiving and emitting counters when relaying a setup
attemp.

This group contains information on the Protocol Errors that
occur at the signalling layer when establishing an ATM SVC.
_5._3._3._2._4. _U_N_I _S_i_g_n_a_l_l_i_n_g _S_u_b-_l_a_y_e_r _S_t_a_t_i_s_t_i_c_s
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 a 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.
Note that some counters do not apply to the proprietary
virtual interface such as the atmSigSSCOPConEvents,
atmSigSSCOPErrdPdus, atmSigSigMsgErrors and atmSigSigRestarts.

A number of Information Elements may or may not be supported
by ATM switches or ATM Service. 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 networks 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
Expires in six months [Page 13]

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.

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
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

This table contains an ATM Interface Administrative Address
Table (atmIfAdminAddrTable) which lists valid addresses for
calls to and from a given interface. One of these numbers
shall be specified as the "default" number. See also section

In the atmVclAddrBindTable, the object atmVclAddrBindAddr 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. While, the ATM Remote address represents the
address of the ATM application at the other end of the VCL.

to the atmVclTable by an ATM address.
_5._3._9. _A_T_M _V_P_L _S_t_a_t_i_s_t_i_c_s _T_a_b_l_e
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 in to 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 [9] and
[10] for the description of the traffic policing.
In the switch where the traffic policing is not supported,
cells are passed or discarded depending on the bandwidth of
the switching fabric. The Output Tagged Cells counter, in
this case, is always zero.

Figure 5. ATM Cell Counters per VPL
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 substracting
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 to the total cells out count minus both the CLP=0 cells
and the tagged cells.

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.

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.
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.

The ATM Logical Port Interface Table is used only by devices
supporting 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
1695, with the following exceptions:
* ifType - a new enumerated value of "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.
* 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 as
discussed in [1], with the following
exceptions:
* atmInterfaceMaxVpcs - 0.
* atmInterfaceConfVpcs - 0.
* atmInterfaceIlmiVpi - VPI of the VP
tunnel.

- An entry is created in the ifStackTable, with

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 in to 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 [9] and
[10] for the description of the traffic policing.
In the switch where the traffic policing is not supported,
cells are passed or discarded depending on the bandwidth of
the switching fabric. The Output Tagged Cells counter, in
this case, is always zero.

draft Supplemental ATM Management Objects Sept 1996
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 substracting
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 to the total cells out count minus both the CLP=0 cells
and the tagged cells.

provides an index to the atmSigDescrParamTable defined in this
MIB. This table is an extention to the atmVclTable defined in
the ATM MIB [1].

The ATM Interface Configuration Extention Table contains SVC
information that supplements the atmInterfaceConfTable defined
in [1]. It includes the configured and negotiated minimum
VPI/VCI values per ATM interface. refer to [1] Section 6.4 for
detailed description
The following figure provides an example how the current
minimum VPI/VCI values are derived from the configured minimum
VPI/VCI values and the neighboring minimum VPI/VCI values:
+--------+ +--------+ +--------+
| ATM | IF a IF b | ATM | IF c IF d | ATM |
| Device |--------------| Device |--------------| Device |
+--------+ +--------+ +--------+
IF a: Configured Min VPI Bits = 6 (configured)
Current Min VPI Bits = 8 (negotiated)
IF b: Configured Min VPI Bits = 8 (configured)
Current Min VPI Bits = 8 (negotiated)
IF c: Configured Min VPI Bits = 8 (configured)
Current Min VPI Bits = 8 (negotiated)
IF d: Configured Min VPI Bits = 8 (configured)
Current Min VPI Bits = 8 (negotiated)
Expires in six months [Page 21]
draft Supplemental ATM Management Objects Sept 1996
(between IF a and IF b, the maximum of the two configured
"Min Configured VPI Bits" is 8, so both interfaces set their
"Min Current VPI Bits" to 8. Since IF c and IF d both
are configured with "Min Configured VPI Bits" of 8, they
set their "Min Current VPI Bits" to 8.)

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.

-- In the latter cases, all the N (or N(N-1)/2) entries
-- are associated with a single VPC cross-connect by
