SL-OSW-MIB

Description: MIB for SmartOptics optical switch modules, monitoring per-port input power levels, loss-of-signal thresholds, and switch port operational status

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.

SL-OSW-MIB is a vendor MIB from Smartoptics for the Optical Switch (OSW) module on its SiteLight platform, a component used to physically switch optical signals between fiber paths, often for protection or restoration purposes. It exposes per-port configuration such as input power thresholds and loss-of-signal detection settings for each switch line/port. Its monitoring emphasis is on optical hardware health: slOSWPortConfigInPowerLevel reports the actual received optical power on a port, and slOSWPortConfigLosThreshold defines the threshold below which a loss-of-signal condition is declared, letting operators detect fiber degradation or a disconnected patch before it triggers an outage. The slOSWPm branch suggests supplementary performance-monitoring data collected per port. It is part of the SiteLight family alongside SL-OPT-APS-MIB, with which it likely cooperates for optical-layer protection switching, and is deployed in DWDM/optical transport nodes requiring physical fiber-path switching, where SL-OSW-MIB SNMP monitoring helps catch fiber degradation before it triggers loss-of-signal alarms.

An engineer would poll slOSWPortConfigTable/slOSWPortConfigEntry indexed by slOSWPortConfigLineIndex to read slOSWPortConfigInPowerLevel for each switch port, comparing it against slOSWPortConfigLosThreshold to see how close a given port is to declaring loss of signal. A steadily dropping input power level nearing the configured threshold would warn of fiber degradation before an actual LOS trap fires from slOSWTraps, prompting preventive maintenance on that fiber run.
