What Is PAIRGAIN-ATMTEST-MIB?

PAIRGAIN-ATMTEST-MIB is a proprietary MIB from PairGain Technologies (a DSL/access equipment vendor later part of ADC/Tellabs) used to configure and run OAM loopback connectivity tests against ATM virtual channel connections on its DSL access equipment. It exposes a loopback test table where an operator defines the target VPI/VCI, loopback type and location, how many test cells to send, timeout/delay parameters, and whether a trap should fire on test completion. Its monitoring role is fault/diagnostic-oriented rather than continuous telemetry: it lets a technician actively verify whether a specific ATM circuit is passing traffic correctly by initiating a loopback and observing the result, used to isolate a faulty DSL/ATM path during troubleshooting. It depends on the underlying ATM OAM (Operations, Administration and Maintenance) loopback cell mechanisms defined in ATM Forum/ITU-T standards for its testing semantics. It is deployed by DSL/ATM access network operators to remotely diagnose connectivity problems on PairGain access equipment without needing a truck roll. Engineers can download the PAIRGAIN-ATMTEST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PAIRGAIN-ATMTEST-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

A technician configures pgoamLoopbackTable / pgoamLoopbackEntry for a given pgoamLoopbackIfIndex, setting pgoamLoopbackVpi/pgoamLoopbackVci to identify the target virtual channel, pgoamLoopbackType and pgoamLoopbackLocation to specify the loopback point, and pgoamLoopbackCount/pgoamLoopbackTimeout to control the test. Enabling pgoamLoopbackTrapOnCompletion means the device sends a notification via pgoamLoopbackMIBTraps once the test finishes, letting the technician judge from pgoamLoopbackDelay whether the round-trip response indicates a healthy circuit or a failing DSL segment.

What Can Be Monitored

ATM loopback test configuration (VPI/VCI, type, location)
loopback test completion/result
loopback round-trip delay
test trap notifications

OIDs

OID symbolic	OID numeric	Type	Access	Description
pgATMTestMIB	1.3.6.1.4.1.927.1.9.9			A MIB module for testing ATM Virtual Channel connections.
pgATMTestMIBObjects	1.3.6.1.4.1.927.1.9.9.1
OCT pgoamLoopbackAddress	1.3.6.1.4.1.927.1.9.9.1.1	OCTET STRING	read-write	Specifies the local ATM device�s ATM address. Other ATM devices use the ATM address to identify this local ATM device as the device that is being requested to loopback the OAM Loopback cell.
pgoamLoopbackTable	1.3.6.1.4.1.927.1.9.9.1.2		not-accessible	A table of OAM loopback request entries.
pgoamLoopbackEntry	1.3.6.1.4.1.927.1.9.9.1.2.1		not-accessible	A OAM loopback request entry. Each entry in the table is uniquely identified by ifIndex, VPI and VCI. To start a test, use NMS to create the associated instance of the row status and row owner objects. Also use NMS to modify the default values for the other configuration objects if the defaults are not appropriate. Once you have used NMS to create the appropriate instance of all of the configuration objects, either by an explicit SNMP set request or by default, use NMS to set the row status to active to initiate the request. Note that this entire procedure can be initiated using a single set request that specifies a row status of createAndGo as well as the valid values for the non-defaulted configuration objects. once the OAM test sequence has been activated, it can be aborted by setting RowStatus from active to notInService. Once the test sequence completes, the NMS should retrieve the values of the status objects of interest and then delete the entry. To prevent old entries from clogging the table, whenever a new OAM loopback test is requested on a VPI VCI, the old VPI VCI entry is deleted and the entries marked expired are also deleted.
I32 pgoamLoopbackIfIndex	1.3.6.1.4.1.927.1.9.9.1.2.1.1	Integer32	read-only	The interface of the connection on which F5 OAM loopbacks are to be sent. Once an instance of this object is created, its value can not be changed. The value specified for this object must equate to a value of ifIndex in the ifTable.
INT pgoamLoopbackVpi	1.3.6.1.4.1.927.1.9.9.1.2.1.2	INTEGER	read-only	The VPI of the connection on which F4/F5 OAM loopbacks are to be sent.
INT pgoamLoopbackVci	1.3.6.1.4.1.927.1.9.9.1.2.1.3	INTEGER	read-only	The VCI of the connection on which OAM loopback cells are to be sent.
INT pgoamLoopbackType	1.3.6.1.4.1.927.1.9.9.1.2.1.5	INTEGER	read-create	Specifies the type of OAM loopback to be performed: segment loopbacks (1) or end to end loopbacks (2). The default is segment loopbacks (1).
OCT pgoamLoopbackLocation	1.3.6.1.4.1.927.1.9.9.1.2.1.6	OCTET STRING	read-create	Specifies the target ATM device�s ATM address to be placed in the 'Loopback Location ID' field of the OAM loopback cell. It is used only when pgoamLoopbackType is set to segment (1).
INT pgoamLoopbackCount	1.3.6.1.4.1.927.1.9.9.1.2.1.7	INTEGER	read-create	Specifies the number of OAM loopback cells (1 to 10) to send to the target in this test sequence. The default is 1 cell.
INT pgoamLoopbackTimeout	1.3.6.1.4.1.927.1.9.9.1.2.1.8	INTEGER	read-create	Specifies the amount of time (5 to 15 seconds) to wait for a response from one transmitted OAM loopback cell before declaring the OAM loopback cells as 'dropped.' The default is 5 seconds.
INT pgoamLoopbackDelay	1.3.6.1.4.1.927.1.9.9.1.2.1.9	INTEGER	read-create	Specifies the minimum amount of time (5 to 15 seconds) to wait before sending the next OAM loopback cell in a test sequence after receiving a response or declaring a timeout for a previous OAM cell. The actual delay may be greater due to internal task scheduling. The default is 5 seconds.
T/F pgoamLoopbackTrapOnCompletion	1.3.6.1.4.1.927.1.9.9.1.2.1.10	TruthValue	read-create	Specifies whether an oamLoopbackCompletion trap should be issued on completion of the test sequence of OAM loopback cells. If such a trap is desired, it is the responsibility of NMS to ensure that the SNMP administrative model is configured to allow the trap to be delivered.
C32 pgoamLoopbackSentCells	1.3.6.1.4.1.927.1.9.9.1.2.1.11	Counter32	read-only	The number of OAM loopback cells that have been sent to the target in this test sequence.
C32 pgoamLoopbackReceivedCells	1.3.6.1.4.1.927.1.9.9.1.2.1.12	Counter32	read-only	The number of OAM loopback cells that have been received from the target in this test sequence.
C32 pgoamLoopbackErroredCells	1.3.6.1.4.1.927.1.9.9.1.2.1.13	Counter32	read-only	The number of OAM Loopback cells that have been received with CRC errors.
INT pgoamLoopbackStatus	1.3.6.1.4.1.927.1.9.9.1.2.1.14	INTEGER	read-only	Set to null (1) when there is no status to report. Set to inProgress (2) as soon as the first OAM loopback cell is sent. Set to completed (3) when all the OAM loopback cells in this test sequence have been responded to or timed out. Set to aborted (4) when the OAM loopback test is aborted by setting pgoamLoopBackEntryStatus to notInService. Set to failed (5) when the OAM loopback cells in this test sequence were timed out, not sent, or not returned. Set to expired (6) 5 minutes after the operation is aborted , completed or failed. When the Status is Expired, the next set operation will automatically delete this entry.
STR pgoamLoopbackEntryOwner	1.3.6.1.4.1.927.1.9.9.1.2.1.15	OwnerString	read-create	The NMS entity that configured this entry.
ROW pgoamLoopbackEntryStatus	1.3.6.1.4.1.927.1.9.9.1.2.1.16	RowStatus	read-create	The status of this table entry. Once the entry status is set to active, the associate entry cannot be deleted until the test sequence completes (oamLoopbackStatus is set to completed). But it can be set to notInService to abort the ongoing loopback Test
INT pgoamLoopbackFlowType	1.3.6.1.4.1.927.1.9.9.1.2.1.17	INTEGER	read-write	This object identifies if the cells are of F4/F5 type when value of this object is set to oamF4, the value of pgoamloopbackVci has to be set to 3 or 4, else the agent should return error
pgATMTestMIBTrapPrefix	1.3.6.1.4.1.927.1.9.9.2

pgATMTestMIBConformance	1.3.6.1.4.1.927.1.9.9.3
pgATMTestMIBCompliances	1.3.6.1.4.1.927.1.9.9.3.1
