Description: Manages Coriolis Networks optical port configuration, laser state, wavelength assignment, and optical power level monitoring.

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 PORT-MIB?

PORT-MIB is a vendor-specific enterprise MIB from Coriolis Networks, an optical networking equipment vendor, covering the line cards installed in Coriolis chassis-based optical switching/transport boxes. Per its short description it exposes per-port optical configuration and status such as laser state, wavelength assignment, and optical power level. This makes it a hardware-health monitoring MIB in the classic sense: laser on/off state and optical power readings are the primary indicators used to catch a degrading transceiver or fiber path before a link actually fails. No object list was available in this batch to confirm dependencies, but MIBs of this kind typically layer port/card indexing on top of ENTITY-MIB for physical inventory. It is typically deployed in metro or DWDM optical transport networks where an NMS polls per-port optical parameters for proactive fault detection, typically after an operator obtains the PORT-MIB download from Coriolis Networks to load into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PORT-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

  • Coriolis Networks optical switch/chassis line cards

Monitoring Examples

No sample_objects were provided for this MIB in the data given, so a concrete table/object-level monitoring scenario cannot be honestly constructed here; based on the short description, an admin would typically poll per-port laser state and optical power level objects to catch a failing laser or degrading fiber path before the link drops, but the exact table/object names are not available in this batch.

What Can Be Monitored

  • laser on/off state
  • wavelength assignment
  • optical power level
  • port/card operational status
