Description: Manages Quantum Bridge SONET interface configuration, section/line/path overhead parameters, and APS switching.

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 QB-SONET-MIB?

QB-SONET-MIB is a Quantum Bridge Communications proprietary MIB that extends the standard SONET MIB with additional objects for managing SONET links on Quantum Bridge transport devices. It belongs to the optical/SONET transport equipment area and supplements standard section, line, and path overhead parameters with vendor-specific management data, including support for Automatic Protection Switching (APS). Its monitoring relevance is fault and performance status of SONET links: overhead byte configuration, alarm/defect conditions, and APS switchover events that indicate a protected SONET circuit has failed over to its standby path due to a line fault. It has an explicit stated dependency on the standard SONET MIB (RFC 2558 family), which this module augments rather than replaces. It is typically deployed on Quantum Bridge SONET add/drop multiplexers or transport network elements at the optical edge of a service provider network. Network engineers evaluating or troubleshooting this functionality can download the QB-SONET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in QB-SONET-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

Only the conformance objects qbSonetCompliances and qbSonetGroups were captured as sample objects, so this MIB's visible sample content is a conformance statement rather than runtime data leaves. In practice, given the module description, an operator would use the underlying per-link objects (not present in the sample) to monitor APS protection-switch state and SONET section/line/path overhead settings, watching for an unexpected APS switchover as an indicator of a fiber cut or line-card fault; a concrete object name for that cannot be honestly given without data beyond the two compliance/group objects provided.

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
qbSonetMIB	1.3.6.1.4.1.4323.2.6			This module defines additional objects for management of SONET links in Quantum Bridge devices, above and beyond what is defined in the standard SONET mib.
qbSonetObjects	1.3.6.1.4.1.4323.2.6.1
INT qbSonetAlarmMode	1.3.6.1.4.1.4323.2.6.1.1	INTEGER	read-write	Setting this object causes enabling or disabling optical ports alarms(LOS, LF, SD or SF). At initial start up time all optical ports are enabled. The user can change the port state to 'disabled' if there are not connections configured on the port. Upon configuring the first active connection to the optical port, the system automatically enables the port alarms. This object is used in conjunction with qbSonetSlot object which defines a scope of the configuration parameter: chassis wide or slot wide. enabled(1) - enables alarms on the selected slot or chassis. disabled(2) - disables alarms on the dormant optical ports of the selected slot or chassis. When read, the value of the object is always 'unknown(3)' This parameter is applied to WAN622, S622, and Q155 cards.
INT qbSonetScramblingMode	1.3.6.1.4.1.4323.2.6.1.2	INTEGER	read-write	Setting this object defines whether ATM cell payload is enabled or disabled. At initial start up time scrambling is set to 'enabled(1)' This object is used in conjunction with qbSonetSlot object which defines a scope of the configuration parameter: chassis wide or slot wide. enabled(1) - enables alarms on the selected slot or chassis. disabled(2) - disables alarms on the dormant optical ports of the selected slot or chassis. When read, the value of the object is alwayd 'unknown(3)' This parameter is applied to WAN622, S622, and Q155 cards.
QBS qbSonetMediumType	1.3.6.1.4.1.4323.2.6.1.3	QbSonetType	read-write	Setting this object defines whether SONET, SDH, SDHDS1, or SONETM13 signal is used across the chassis/slot. At initial start up the object is set to 'sonet(1)' This object is used in conjunction with qbSonetSlot object which defines a scope of the configuration parameter: chassis wide or slot wide. sonet(1) - sets signal format to 'sonet'. sdh(2) - sets signal format to 'sdh/VC12' sdhDs1(2) - sets signal format to 'sdh/VC11' sonetM13(2) - sets signal format to 'sonet/M13 payload' When read, the value of the object is always 'unknown(3)' This parameter is applied to D155VT/VC-T.
INT qbSonetSlot	1.3.6.1.4.1.4323.2.6.1.4	INTEGER	read-write	This object defines a scope of the applied configuration parameter. If the object is set to non-zero value all ports of the defined slot are configured. When object is set to 0, this setting is applied to all applicable optical cards.
