NBS MIBs

NBS's MIBs in this database are all built around optical transport equipment: DWDM systems, ROADMs, optical amplifiers (OBA), tunable laser transceivers, and optical spectrum analyzers, rather than general Ethernet switching. The recurring monitoring data is optical-transport specific: OTN overhead and performance metrics (errored/severely-errored/unavailable seconds), forward error correction statistics, signal-lane wavelength and power levels, and equipment/link redundancy protection switching. Come here if you're managing an NBS optical transport or DWDM shelf and need the NBS-ROADM, NBS-OTNPM, or NBS-SIGLANE MIBs to track wavelength health and FEC performance alongside the more familiar NBS-STATS interface counters. Because many modules track different layers of the same optical path (jumpers, lanes, OTN overhead, FEC), pull from several NBS-* MIBs together rather than expecting one module to cover a whole optical circuit.
