CYAN-ETH-MIB

Description: Manages Ethernet interface configuration and statistics for Cyan optical transport platforms.

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.

CYAN-ETH-MIB is a Cyan Inc. proprietary MIB for its Z-Series optical transport/packet-optical platforms, covering the Ethernet Termination (ETH) function that maps Ethernet client traffic onto the optical transport layer. It exposes per-termination-point configuration and status identified by shelf, module, and Ethernet-termination indices, including administrative state, an in-service 'soak time' used when bringing a port up, flow-point pooling subtype, and identifiers for the far-end network element (shelf, slot, system, and PTP IDs) that the local port connects to. For monitoring, cyanEthAdminState is the primary interface/hardware status signal — confirming whether a given Ethernet termination is administratively up, down, or in a soak/testing period — while the far-end identifier fields let an operator verify that a termination point is connected to the expected remote shelf/slot rather than a misprovisioned neighbor. It depends on Cyan's broader chassis/shelf MIB structure for shelf and module identification context. It is deployed in metro and long-haul optical transport networks using Cyan (later Ciena Z-Series) packet-optical platforms. Engineers can download the CYAN-ETH-MIB file directly to load it into their MIB browser.

An operator polling cyanEthTable/cyanEthEntry would check cyanEthAdminState per cyanEthShelfId/cyanEthModuleId/cyanEthEthTermId to confirm a given Ethernet termination point is in service. Comparing cyanEthFarEndShelfId/cyanEthFarEndSlotId/cyanEthFarEndSystemId against the expected topology reveals cross-connect or fiber-patching errors where a port unexpectedly links to the wrong far-end system. cyanEthAutoinserviceSoakTimeSec would be checked when a newly activated port is still in its soak period rather than fully in service.
