What Is ATM-SOFT-PVC-MIB?
ATM-SOFT-PVC-MIB is an ATM Forum/IETF-derived standards MIB for managing ATM Soft Permanent Virtual Circuits (Soft PVCs), a hybrid ATM connection type that combines PVC-like provisioning with SVC-style dynamic call setup. It exposes configuration for soft PVC endpoints, including target address, VPI/VCI selection, and call setup parameters, along with counters and flags for call failure tracking. Its monitoring value is centered on fault detection for these ATM connections: it tracks the count of soft PVC call failures, the number of currently failing soft PVCCs and PVPCs, and can generate traps at a configurable notification interval when failures occur, directly surfacing connection-level fault status on ATM switching equipment. As an ATM Forum-aligned standard it works alongside other standard ATM MIBs (such as the base ATM-MIB) for complete circuit management. It is deployed in carrier and enterprise ATM switch networks using soft PVCs for resilient virtual circuit provisioning. When decoding a specific fault trap, an operator can consult the ATM-SOFT-PVC-MIB OID list to map the numeric identifier back to the exact soft-PVC object it represents.
IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-SOFT-PVC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- ATM switch/router supporting Soft PVC (ATM Forum-compliant)
Monitoring Examples
An administrator would poll atmSoftPvcCallFailures and atmSoftPvcCurrentlyFailingSoftPVccs/atmSoftPvcCurrentlyFailingSoftPVpcs to detect ATM soft virtual circuits that are currently unable to establish a call, indicating a routing or endpoint reachability problem. Examining atmSoftPVccTable/atmSoftPVccEntry, indexed by atmSoftPVccLeafReference, would show the atmSoftPVccTargetAddress, atmSoftPVccTargetVpi, and atmSoftPVccTargetVci for a specific failing circuit, while atmSoftPvcCallFailuresTrapEnable and atmSoftPvcNotificationInterval control whether and how often traps are sent for these failures.
What Can Be Monitored
- soft PVC call failure count
- currently failing soft PVCCs/PVPCs
- target address, VPI/VCI for soft PVC endpoints
- call failure trap enable/interval

| atmSoftPVccEntry | 1.3.6.1.4.1.353.5.5.1.1.2.1 | not-accessible | Each entry in this table represents a Soft Permanent Virtual Channel Connection (Soft PVCC) originating at a switch interface. A Soft PVCC is a VCC that is: - provisioned at the originating (source) interface of the connection - established by signalling procedures across a network to a destination interface. A row in the atmVclTable must be created, defining a VCL on the source interface, prior to creating an atmSoftPVccEntry row. The row in the atmVclTable must be active prior to activating the atmSoftPVccEntry row. The contents of this table reflect only the characteristics unique to a Soft PVCC. The traffic parameters are defined in the VCL row for the source interface, as specified in the ATOMMIB (RFC1695) and the forthcoming addition, the Supplemental ATOMMIB. Note that the atmSigDescrParamTable contains some objects such as the AAL parameters, Broadband high layer information and Broadband low layer information elements which are used to carry end-to-end information. For this reason, these objects are not relevant to Soft PVCCs. When a row is made active, an attempt is made to set up a switched connection to an interface at the destination switch. No objects (other than atmSoftPVccRowStatus) can be set while the row is active. At the destination, the VCL may be defined (but not cross-connected) prior to arrival of the Setup request. The combination of ifIndex, atmVclVpi, and atmVclVci specified in the index clause of this entry serves to identify the VCL on the source interface. The atmSoftPVccLeafReference object aids in distinguishing between leaves of a point-to-multipoint Soft PVCC. | |
| INT atmSoftPVccLastReleaseCause | 1.3.6.1.4.1.353.5.5.1.1.2.1.6 | INTEGER | read-only | Value of the Cause field of the Cause Information Element in the last RELEASE signalling message received for this Soft PVCC. Indicates the reason for the Release. |
| OCT atmSoftPVccLastReleaseDiagnostic | 1.3.6.1.4.1.353.5.5.1.1.2.1.7 | OCTET STRING | read-only | Value of the first 8 bytes of diagnostic information from the Cause field of the Cause Information Element in the last RELEASE signalling message received for this Soft PVCC. |
| INT atmSoftPVccLeafReference | 1.3.6.1.4.1.353.5.5.1.1.2.1.1 | INTEGER | not-accessible | An arbitrary integer which, in the case of the source VCL having an atmVclCastType of 'p2mpRoot', serves to distinguish between the multiple leaves attached to a root of a point-to-multipoint Soft PVCC. If the atmVclCastType is not 'p2mpRoot' the value 1 shall be used. |
| INT atmSoftPVccOperStatus | 1.3.6.1.4.1.353.5.5.1.1.2.1.8 | INTEGER | read-only | Describes the status of the Soft PVCC. Valid values are: other - none of the types specified below establishmentInProgress - connection or party is not operational, but setup or add party attempts are ongoing connected - connection or party is currently operational retriesExhausted - retry limit has been reached and setup or add party attempts have ceased noAddressSupplied - no remote address has been configured, so no setup or add party attempts are initiated lowerLayerDown - underlying ATM interface is not operational When the row is not 'active', the value of this object is 'other'. |
| INT atmSoftPVccRestart | 1.3.6.1.4.1.353.5.5.1.1.2.1.9 | INTEGER | read-write | When the value is set to 'restart' the Soft PVCC is released if necessary and a new setup procedure is begun. As a result of this action, the atmSoftPVccOperStatus object transitions to 'establishmentInProgress' (if not already in this state) and the atmSoftPVccRetryFailures object is cleared When the value is set to 'noop' no operation is performed. When read, the value 'noop' is returned. |
| G32 atmSoftPVccRetryFailures | 1.3.6.1.4.1.353.5.5.1.1.2.1.13 | Gauge32 | read-only | Indicates how many attempts to establish the connection have failed. This count is reset whenever a connection is successfully established or the Soft PVCC is restarted. |
| INT atmSoftPVccRetryInterval | 1.3.6.1.4.1.353.5.5.1.1.2.1.10 | INTEGER | read-write | Defines the period to wait before attempting to establish the Soft PVCC after the first failed call attempt. The time to wait between subsequent call attempts may differ to implement a backoff scheme. Zero represents an infinite interval indicating no retries. |
| INT atmSoftPVccRetryLimit | 1.3.6.1.4.1.353.5.5.1.1.2.1.14 | INTEGER | read-write | Sets a maximum limit on how many consecutive unsuccessful call setup attempts can be made before stopping the attempt to set up the connection. If this limit is reached then management action will be required (e.g. setting atmSoftPVccRestart to 'restart') to initiate a new attempt to establish the connection. A value of zero indicates no limit - the attempts will continue until successful. |
| INT atmSoftPVccRetryThreshold | 1.3.6.1.4.1.353.5.5.1.1.2.1.12 | INTEGER | read-write | Indicates the number of consecutive call setup attempts for the same Soft PVCC which need to fail before the atmSoftPvcCallFailures object is incremented. A value of zero indicates that an infinite number of call attempts are required to increment the atmSoftPvcCallFailures object and thus disables alarms for the Soft PVCC. |
| INT atmSoftPVccRetryTimer | 1.3.6.1.4.1.353.5.5.1.1.2.1.11 | INTEGER | read-only | Indicates the current value of the retry timer for this connection. When the value reaches zero an attempt will be made to establish the Soft PVCC. When the timer is not running, the value zero shall be returned. |
| ROW atmSoftPVccRowStatus | 1.3.6.1.4.1.353.5.5.1.1.2.1.15 | RowStatus | read-write | Used to create and delete a Soft PVCC. When this object is set to 'active' an attempt is made to set up the Soft PVCC. When this object has the value 'active' and is set to another value, any set-up or connection in-progress is released. |
| atmSoftPVccTable | 1.3.6.1.4.1.353.5.5.1.1.2 | not-accessible | The (conceptual) table used to manage Soft Permanent Virtual Channel Connections (Soft PVCCs). The Soft PVCC table is applicable only to switches. | |
| ATM atmSoftPVccTargetAddress | 1.3.6.1.4.1.353.5.5.1.1.2.1.2 | AtmAddr | read-write | The target ATM Address of this Soft PVCC. If no address is supplied, no attempts to establish the Soft PVCC are initiated. |
| INT atmSoftPVccTargetSelectType | 1.3.6.1.4.1.353.5.5.1.1.2.1.3 | INTEGER | read-write | Indicates whether the target VPI/VCI values are to be used at the destination. If the value 'any' is specified, the destination switch will choose the VPI/VCI values. In such a case, once the Soft PVCC atmSoftPVccOperStatus value is 'connected', the value of this object changes to 'required', such that the same VPI/VCI values will continue to be used even if the connection is subsequently torn down and re-established. The VPI/VCI values chosen will be available for reading in atmSoftPVccTargetVpi and atmSoftPVccTargetVci. If the value 'required' is specified, then values must be supplied for objects atmSoftPVccTargetVpi and atmSoftPVccTargetVci prior to activation of the row. These values are then to be used at the destination. |
| INT atmSoftPVccTargetVci | 1.3.6.1.4.1.353.5.5.1.1.2.1.5 | INTEGER | read-write | The VCI value of the VCL used at the target interface. This value must be filled in when the atmSoftPVccTargetSelectType is set to 'required'.This value is not relevant when the value of atmSoftPVccTargetSelectType is 'any'. |
| INT atmSoftPVccTargetVpi | 1.3.6.1.4.1.353.5.5.1.1.2.1.4 | INTEGER | read-write | The VPI value of the VCL used at the target interface. This value is not relevant when the value of atmSoftPVccTargetSelectType is 'any'. |
