          _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.

          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.

          draft        Supplemental ATM Management Objects     Sept 1996

          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

          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.

          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.

          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

          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.

          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

          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).

          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:

          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.

          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.

          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

          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.

          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

          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].

          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.

          This table provides an alternative way to retrieve the

          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.

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

          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.

          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

          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.

          This table contains the general information for each VCs.  It
          provides an index to the atmSigDescrParamTable defined in this

                 "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.

                 sort of incorrect information in a message.  This
                 includes:
          
          
                 - RELEASE, RELEASE COMPLETE, ADD PARTY REJECT,
                   and STATUS messages transmitted or
                   received, that contain any of the Cause values
                   listed below.
          
                 - Ignored messages.  These messages are dropped
                   because the message was so damaged that it could
                   not be further processed.  A list of dropped
                   messages is compiled below:
          
                    1.  Message with invalid protocol discriminator
          
                    2.  Message with errors in the call reference I.E.
                         - Bits 5-8 of the first octet not equal to
                           '0000'
                         - Bits 1-4 of the first octet indicating a
                           length other than 3 octets
                         - RELEASE COMPLETE message received with a
                           call reference that does not relate to a
                           call active or in progress
                         - SETUP message received with call reference
                           flag incorrectly set to 1
                         - SETUP message received with a call
                           reference for a call that is already
                           active or in progress.
