Description: Manages IP virtual circuit (IVC) table entries and ATM/Frame Relay PVC configuration on AI-series network devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is AIIPVCTABLE-MIB?

AIIPVCTABLE-MIB is a vendor MIB for AI-series network devices that manages IP virtual circuit (IVC) entries, covering Permanent Virtual Circuit (PVC) configuration for ATM and Frame Relay style connections. It exposes a PVC table describing each circuit's interface binding, interface type, circuit identifier, and status, along with call and inactivity timers governing circuit lifecycle. In monitoring terms it supports checking each PVC's operational status (up/down/failed) and timer-driven behavior, which functions as a connectivity/software-state health indicator for WAN circuits rather than physical hardware sensors. No explicit dependency on other standard MIBs is stated, though its concepts parallel standard ATM/Frame Relay MIB structures. It is typically deployed on AI-series routers or WAN access devices provisioning legacy ATM/Frame Relay PVCs alongside IP, and the AIIPVCTABLE-MIB MIB remains a key reference for engineers troubleshooting these circuits.

IPNetwork Monitor allows you to monitor SNMP objects defined in AIIPVCTABLE-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

AI-series routers/WAN access devices (ATM/Frame Relay capable)

Monitoring Examples

An administrator would poll aiPVCTable/aiPVCEntry, keying on aiPVCIfIndex and aiPVCCircuit, to check aiPVCStatus for each configured circuit and confirm it reads active rather than down or failed. The aiPVCIfType column identifies whether a given entry is ATM- or Frame-Relay-backed, while aiPVCCallTimer and aiPVCInactivityTimer reveal whether a circuit has been idle long enough to be torn down. A sudden status change across multiple aiPVCEntry rows sharing the same aiPVCIfIndex would suggest an underlying physical interface flap rather than an individual circuit fault.

OIDs

OID symbolic	OID numeric	Type	Access	Description
aii	1.3.6.1.4.1.539
aiSLC2	1.3.6.1.4.1.539.16
aiPVC	1.3.6.1.4.1.539.16.1			The MIB module for the PVC Table
aiPVCTable	1.3.6.1.4.1.539.16.1.1		not-accessible	Entries define permanent virtual circuits (PVCs) in the system. Each entry contains enough information to create one PVC on one network interface. Each entry may also contain the information required to create another circuit in the system, of any kind. This other circuit we will call a companion circuit, since eventually it is going to be connected to the PVC defined in the same entry. This connection information does not need to be present, but may be, to allow for a rapid association between a PVC and its companion circuit.
aiPVCEntry	1.3.6.1.4.1.539.16.1.1.1		not-accessible	Entries of aiPVCTable.
ROW aiPVCStatus	1.3.6.1.4.1.539.16.1.1.1.1	RowStatus	read-create	The status of this PVC entry. See RFC 1443 for details of usage.
IAN aiPVCIfType	1.3.6.1.4.1.539.16.1.1.1.2	IANAifType	read-write	The type of subnetwork on which this PVC is to be created. Examples are frameRelay(32), and x25ple(40).
IFI aiPVCIfIndex	1.3.6.1.4.1.539.16.1.1.1.3	IfIndexType	read-write	The index into the interfaces group of MIB-II, which defines the particular subnetwork on which this PVC will be created. This index corresponds to what AII calls a link.
NUM aiPVCCircuit	1.3.6.1.4.1.539.16.1.1.1.4	PositiveInteger	read-write	The individual circuit number on the subnetwork (defined by aiPVCIfIndex), to which the PVC defined by this entry is mapped. In X.25, this number maps directly to a Logical Channel Number. In Frame Relay, this number maps directly to a DLCI. In other words, this object, and aiPVCIfIndex, tell the SLC where a PVC is located.
UNS aiPVCCallTimer	1.3.6.1.4.1.539.16.1.1.1.5	UnsignedShort	read-write	The time, in seconds, between successive attempts to create a composite circuit comprising the PVC defined in this entry, and its companion circuit. When a PVC is created, if its aiPVCCallTimer is greater than zero, then the PVC will attempt to connect to a remote host (as specified elsewhere). If the connection attempt times out before completion, then the PVC will try again after aiPVCCallTimer seconds.
UNS aiPVCInactivityTimer	1.3.6.1.4.1.539.16.1.1.1.6	UnsignedShort	read-write	The time, in seconds, of inactivity on a composite circuit before a PVC will tear down the composite circuit. Once a composite circuit has been created, comprising a PVC and its companion circuit, then if the PVC's aiPVCInactivityTimer is greater than zero, and if no data passes through the composite circuit in either direction for aiPVCInactivityTimer seconds, then the PVC will close the composite circuit.
aiPVCConformance	1.3.6.1.4.1.539.16.1.2
aiPVCGroups	1.3.6.1.4.1.539.16.1.2.1
aiPVCGroup	1.3.6.1.4.1.539.16.1.2.1.1			A collection of objects providing information applicable to all AII cal parameter name tables.
aiPVCCompliances	1.3.6.1.4.1.539.16.1.2.2
aiPVCCompliance	1.3.6.1.4.1.539.16.1.2.2.1			The compliance statement for SNMPv2 entities which have AII PVC tables.
