Description: Root management MIB for SmartOptics SiteLight main control card, covering system info, authentication, trap configuration, software versions, log and configuration file management

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 SL-MAIN-MIB?

SL-MAIN-MIB is the root management module for the Main Control Board of SmartOptics's SiteLight optical transport platform, covering system identity, IP networking, authentication, alarms, trap configuration, and software/log/configuration file management. It belongs to the optical-transport-equipment category and exposes a broad mix of configuration data (IP/gateway/subnet), administrative and operational status, and software version tracking. Its monitoring emphasis spans both hardware and software status: slmSysOperStatus and slmSysAdminStatus reflect the control card's operational health, slmSysActiveSwVersion and slmSwRevTable track deployed firmware/software versions, and slmSysCalendarTime/slmSysPmStartOfDay support time-aligned performance monitoring, while alarm activation/deactivation objects (slmSysAlmAct/slmSysAlmDeact) surface fault conditions. It likely relies on SmartOptics's broader per-module MIBs (such as SL-ROADM-MIB or SL-SONET-APS-MIB) which share this main board's system context. It is deployed on SmartOptics SiteLight optical transport chassis in metro/regional DWDM or ROADM network deployments. Loading SL-MAIN-MIB in a MIB Browser exposes this full mix of system, alarm, and software-version objects under a single control-board OID branch, making it a convenient starting point for exploring the SiteLight platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in SL-MAIN-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

  • SmartOptics SiteLight optical transport main control card/chassis

Monitoring Examples

An operator would poll slmSysOperStatus and slmSysAdminStatus to confirm the Main Control Board is administratively enabled and operationally up, and check slmSysActiveSwVersion against slmSwRevTable to verify the running software matches the expected release after an upgrade. Monitoring slmSysAlmAct/slmSysAlmDeact reveals active or cleared alarm conditions on the chassis, useful for catching a control-card fault. Tracking slmSysCalendarTime alongside slmSysPmStartOfDay ensures performance-monitoring bins align correctly with the device's clock, which matters when correlating PM data across the network.

What Can Be Monitored

  • administrative and operational status
  • active software version
  • software revision history
  • alarm activation/deactivation events
  • system IP/gateway/subnet configuration
  • system clock and PM interval start time

How to Use in IPNetwork Monitor

Example using slmSysTemperature OID:

Select a SmartOptics SiteLight optical transport main control card or chassis as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type slmSysTemperature into the Find box to locate it in the OID tree, then select it and click OK. It reports the current temperature of the PL device, in degrees Celsius. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the reported value exceeds the level expected for healthy operation, since sustained high temperature often precedes thermal shutdown or hardware degradation. Click Finish to create the monitor; you can adjust any parameter later.
