Description: Top-level MIB defining the Cyan optical networking management framework and OID hierarchy.
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 CYAN-MIB?
CYAN-MIB is the top-level MIB module for Cyan Inc.'s (Cyan Optics) packet-optical networking management framework, establishing the overall OID hierarchy and shared conventions used by the vendor's other Cyan-specific MIBs. Rather than exposing individual device sensors directly, it centers on a rich alarm/event model, defining objects for alarm probable cause, severity, source type/address, node name, and reporting timestamp, alongside a generic event-type object. This makes it fundamentally a fault-management MIB: its alarm severity, probable-cause, and state objects are the primary mechanism for monitoring hardware and service faults across a Cyan optical network element. It follows patterns similar to ITU-T/Telcordia alarm/event models common in optical transport equipment and is depended upon by other Cyan product-specific MIBs that extend this common alarm framework. It is deployed in Cyan (later Ciena) packet-optical transport platforms used by service providers for metro/regional optical networking. The CYAN-MIB MIB module is thus best understood as a fault-management framework rather than a raw hardware sensor MIB.
IPNetwork Monitor allows you to monitor SNMP objects defined in CYAN-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
- Cyan (Ciena) packet-optical transport network element
Monitoring Examples
An NMS subscribed to Cyan alarm notifications would inspect cyanAlarmSeverity and cyanAlarmProbCause to triage an incoming fault, for example a critical-severity alarm pointing to an optical transceiver failure. cyanAlarmSourceAddress and cyanAlarmNodeName identify exactly which network element raised the alarm, while cyanAlarmState and cyanAlarmReportingTimeStamp let an operator track the alarm's raised/cleared lifecycle. cyanEventType provides broader classification for non-alarm events logged by the system.
What Can Be Monitored
- active alarm severity
- alarm probable cause
- alarm source node/address
- alarm state (raised/cleared)
- alarm reporting timestamp
- general event log

FAQ
How does CYAN-MIB support fault monitoring on a Cyan packet-optical network element?
It defines an alarm/event model with objects for probable cause, severity, source type/address, node name, and reporting timestamp, plus a generic event-type object, so an operator can identify what's alarming, how severe it is, where it originated, and when it was raised or cleared across the optical network element.
Is CYAN-MIB used to read hardware sensors directly, or something else?
Something else -- it's fundamentally a fault-management framework rather than a raw hardware sensor MIB; actual per-device sensor readings come from other Cyan product-specific MIBs, while CYAN-MIB's alarm severity, probable-cause, and state objects are the primary mechanism for tracking hardware and service faults.
