Description: Manages PairGain DSL PVC service configuration, ATM virtual circuit parameters, and service provisioning status.

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 PVC-SERVICE-MIB?

PVC-SERVICE-MIB is a PairGain Technologies (later part of the ADC/Westell DSL product line) MIB used to manage Permanent Virtual Circuit (PVC) service provisioning on DSL access equipment, covering both DSL subscriber service records and the underlying ATM virtual circuit parameters. It exposes configuration data describing each subscriber's DSL service assignment - subscriber name, service type, MAC address, IP address and subnet mask - along with ATM PVC parameters such as VPI values for the service access rows. Rather than hardware health, this MIB's monitoring value is in configuration/provisioning status: the row status objects reveal whether a subscriber's service or PVC entry is active, provisioned, or in an inconsistent state, which is useful for tracking DSL service activation and fault isolation. It depends conceptually on standard ATM and DSL-related concepts (VPI/VCI addressing) though it does not appear to formally import from ATM-MIB. It is typically deployed by DSL access equipment operators (COs, ISPs) managing PairGain/ADC DSL access multiplexers provisioning subscriber PVC-based services. Engineers can download the PVC-SERVICE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PVC-SERVICE-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.

Monitoring Examples

An operator would walk pgXdslServiceTable/pgXdslServiceEntry to see each subscriber's pgXdslServiceSubscriberName, pgXdslServiceType, pgXdslServiceIpAddress, and pgXdslServiceMacAddress, then check pgXdslServiceRowStatus to confirm the service row is active rather than notReady or notInService. Cross-checking pgPvcServiceTable/pgPvcServiceEntry and pgPvcServiceSarVpi would reveal whether the ATM PVC underlying that subscriber's service is correctly provisioned, exposing a misconfigured or orphaned PVC if the VPI value does not match the expected provisioning plan.

What Can Be Monitored

subscriber service provisioning status
DSL service type per subscriber
subscriber IP/MAC address assignment
ATM PVC VPI configuration
service/PVC row status (active/provisioned)

pgXdslServiceTable	1.3.6.1.4.1.927.1.9.6.1.1		not-accessible	A table of xDSL port entries that defines the Service Application and other port/interface related parameters needed to use the xDSL port for that service.
pgXdslServiceEntry	1.3.6.1.4.1.927.1.9.6.1.1.1		not-accessible	An entry in the pgXdslServiceTable.
STR pgXdslServiceSubscriberName	1.3.6.1.4.1.927.1.9.6.1.1.1.1	DisplayString	read-write	The Subscriber name.
PGP pgXdslServiceType	1.3.6.1.4.1.927.1.9.6.1.1.1.2	PgPvcServiceType	read-write	The Service name as defined by PgPvcServiceType.
MAC pgXdslServiceMacAddress	1.3.6.1.4.1.927.1.9.6.1.1.1.3	MacAddress	read-write	The Physical(MAC) address of the xDSL port.

ROW pgXdslServiceRowStatus	1.3.6.1.4.1.927.1.9.6.1.1.1.6	RowStatus	read-create	This object allows entries to be created and deleted in this table. The RowStatus should be out of the ACTIVE state for other columns to be modified.
pgPvcServiceTable	1.3.6.1.4.1.927.1.9.6.1.2		not-accessible	A table of PVC entries (as described by pgPvcServiceSarIfIndex and pgPvcServiceSarIfIndex/Vpi/Vci ) that defines the Service Application name such as LANT/PPP etc., and maps the PVC to the xDSL port.
pgPvcServiceEntry	1.3.6.1.4.1.927.1.9.6.1.2.1		not-accessible	The Route information that maps Network numbers to the ifIndex of the xDSL port.
