Category: Nortel MsCarrier MscPassport

Description: Provides SNMP objects for ATM bearer service class configuration on Nortel MsCarrier MscPassport switches.

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 Nortel-MsCarrier-MscPassport-AtmBearerServiceMIB?

This MIB module is part of the Nortel MsCarrier MscPassport family (the rebranded successor to Magellan Passport) and manages ATM bearer service parameters, specifically virtual path connection (VPC) next-hop-resolution and OAM segment configuration on MsCarrier Passport ATM switches. It exposes provisioning data such as the next-hop address, connection point type, and OAM segment boundary flag for each VPC NRP entry, alongside the standard row-status/component-identity objects. Administrators use it to monitor whether ATM bearer connections are correctly provisioned — verifying mscAtmIfVpcNrpConnectionPointType and mscAtmIfVpcNrpOamSegmentBoundary settings and confirming row status is active — reflecting the software-level configuration health of the switch's ATM bearer-service hardware path. It follows the shared MsCarrier Passport component/row-status conventions and depends on ATM Forum bearer-service/OAM concepts for its object semantics. It is deployed on Nortel MsCarrier MscPassport carrier ATM switches providing ATM bearer services with OAM segment monitoring. Network engineers evaluating or troubleshooting this functionality can download the Nortel-MsCarrier-MscPassport-AtmBearerServiceMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-AtmBearerServiceMIB. 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 poll mscAtmIfVpcNrpProvTable/mscAtmIfVpcNrpProvEntry to read mscAtmIfVpcNrpNextHop and mscAtmIfVpcNrpConnectionPointType for a VPC identified by mscAtmIfVpcNrpIndex, confirming the bearer service connection point is configured as expected. Checking mscAtmIfVpcNrpOamSegmentBoundary confirms whether OAM segment monitoring is enabled at that connection point; an unexpectedly disabled boundary flag would mean OAM fault indications aren't being generated for that ATM segment.

For example, the bandwidth may be reduced in the event that one or more physical links in the IMA group fail, such that the originally requested bandwidth cannot be maintained. This attribute shows whether the application running on this connection can continue to operate if the bandwidth is reduced. If the bandwidth is reduced, the amount by which it is reduced will be displayed in the bandwidthReduction attribute. A value of yes, indicates that this connection is elastic, and the bandwidth may be reduced but the connection will not be released. Currently, this attribute should only be set to yes for situations where this Mnrp is functioning as a loopback on one side of an IMA link. There are no other situations where this setting is valid. A value of no indicates that the bandwidth for this connection will not be reduced in the event of link bandwidth reduction. However, this connection may be released based on its holdingPriority.

This attribute specifies whether the AAL5 Partial Packet Discard (PPD) feature has been enabled or disabled on the Nrp in the receive direction. This feature allows the NRP to discard the remainder of a cell-forwarded AAL5 frame if a cell of this frame has been discarded due to congestion or usage parameter control (UPC). This increases the 'goodput' of the link, since cells which are only going to be discarded by the AAL5 reassembly are not transmitted. When this attribute is set to enabled, the PPD feature is applied in the receive direction. It should only be enabled for connections whose end points are performing AAL5 segmentation and reassembly. When this attribute is set to disabled, the PPD feature is not applied to traffic for this connection in the receive direction. When this attribute is set to sameAsTx, the PPD feature for traffic in the receive direction will be configured the same way as it is in the transmit direction. Note that specifying enabled for a non-AAL5 connection will cause all traffic to be discarded once congestion is encountered.

INT mscAtmIfVpcNrpRxAal5PartialPacketDiscard	1.3.6.1.4.1.562.36.2.1.114.4.4.100.1.32	INTEGER	read-write	This attribute is obsolete in P4.2 and has been migrated under Vcd (Vpd) component. This attribute specifies whether the AAL5 Partial Packet Discard (PPD) feature has been enabled or disabled on the Nrp in the receive direction. This feature allows the NRP to discard the remainder of a cell-forwarded AAL5 frame if a cell of this frame has been discarded due to congestion or usage parameter control (UPC). This increases the 'goodput' of the link, since cells which are only going to be discarded by the AAL5 reassembly are not transmitted. When this attribute is set to enabled, the PPD feature is applied in the receive direction. It should only be enabled for connections whose end points are performing AAL5 segmentation and reassembly. When this attribute is set to disabled, the PPD feature is not applied to traffic for this connection in the receive direction. When this attribute is set to sameAsTx, the PPD feature for traffic in the receive direction will be configured the same way as it is in the transmit direction. Note that specifying enabled for a non-AAL5 connection will cause all traffic to be discarded once congestion is encountered.

For example, the bandwidth may be reduced in the event that one or more physical links in the IMA group fail, such that the originally requested bandwidth cannot be maintained. This attribute shows whether the application running on this connection can continue to operate if the bandwidth is reduced. If the bandwidth is reduced, the amount by which it is reduced will be displayed in the bandwidthReduction attribute. A value of yes, indicates that this connection is elastic, and the bandwidth may be reduced but the connection will not be released. Currently, this attribute should only be set to yes for situations where this Mnrp is functioning as a loopback on one side of an IMA link. There are no other situations where this setting is valid. A value of no indicates that the bandwidth for this connection will not be reduced in the event of link bandwidth reduction. However, this connection may be released based on its holdingPriority.

It affects the connection point type value visible in the parent component's connectionPointType attribute. The desired OAM segment boundary can be specified directly as yes, no or sameAsInterface. If sameAsInterface is specified, the OAM segment boundary is same as the oamSegmentBoundary attribute of the associated AtmIf and the switch will set the connectionPointType, choosing segmentEndPoint for a segment- boundary ATM interface and connectingPoint for a non-segment- boundary ATM interface.

Holding priority is used when there is an IMA group where some physical links have failed. Holding priority determines the order in which connections are released. 4 is the lowest holding priority and is released first. 0 is a higher priority and is released last. The value specified in this attribute will override whatever holdingPriority that has been provisioned at the Vcd (or Vpd).
