Description: Tracks SLA performance metrics including latency, jitter, and packet loss measurements on NBS network devices.

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 NBS-SLA-MIB?

NBS-SLA-MIB is an NBase enterprise MIB for representing Service Level Agreement (SLA) test/measurement data, letting a device generate synthetic test traffic and report resulting performance metrics such as latency, jitter, and packet loss. It exposes a traffic generator configuration table controlling frame size, frame count, and inter-packet gap per interface, alongside the action to start/stop a test. It is used to monitor the performance status of network paths rather than the device chassis itself — administrators use SLA test results to confirm a link or path meets contracted latency/jitter/loss targets, and a degraded result flags a network-level fault even when the device's own hardware is healthy. As an active-measurement MIB it conceptually parallels IETF's IPPM/TWAMP-style test frameworks though implemented as an NBase-specific extension. It is typically deployed by service providers on NBase access/transport equipment to continuously validate SLA compliance for business Ethernet or transport services, and engineers can perform an NBS-SLA-MIB download to load these test objects into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NBS-SLA-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

  • NBase-Xyplex network/access switch or transport platform

Monitoring Examples

An admin would configure nbsSlaTrafficGenTable/nbsSlaTrafficGenEntry keyed by nbsSlaTrafficGenIfIndex, setting nbsSlaTrafficGenFrameSize, nbsSlaTrafficGenFrameCount, and nbsSlaTrafficGenInterPacketGap, then trigger nbsSlaTrafficGenAction to run a test on that interface. Resulting performance figures measured against the nbsSlaTrafficGenMaxHeaders/nbsSlaTrafficGenMaxPattern test parameters exceeding the contracted SLA threshold would indicate the path is not meeting its committed service level, prompting investigation of the underlying transport.

What Can Be Monitored

  • SLA test traffic generation state
  • frame size and count for test traffic
  • inter-packet gap
  • per-interface SLA test configuration

How to Use in IPNetwork Monitor

Example using nbsSlaPerfMonFramesAllSizes OID:

Select a NBase-Xyplex network/access switch or transport platform (SLA test/measurement) 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 nbsSlaPerfMonFramesAllSizes into the Find box to locate it in the OID tree, then select it and click OK. The count of all monitored frames. 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 a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
