Category: Frame Relay

Description: Defines managed objects for Frame Relay Service Level Definitions as specified in FRF.13, including metrics such as data delivery ratio and service availability.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring FRSLD-MIB with a free 30-day trial of IPNetwork Monitor.

What Is FRSLD-MIB?

FRSLD-MIB is a vendor-neutral IETF-derived MIB implementing the Frame Relay Forum's FRF.13 Service Level Definitions, which standardize metrics for measuring the quality of service delivered over a Frame Relay network. It exposes objects for service-level performance metrics such as data delivery ratio, frame delay, and service availability, allowing comparison of actual network performance against contracted service levels. Its monitoring focus is performance/service-quality status rather than hardware health, letting an operator track whether a Frame Relay service meets committed availability and delivery-ratio targets over a measurement interval. It explicitly depends on the FRF.13 specification from the Frame Relay Forum and is a standards-based module rather than a proprietary vendor extension. It is deployed by carriers and enterprises as an FRSLD-MIB reference for measuring Frame Relay circuit SLAs across a WAN.

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

  • vendor-neutral, standards-based MIB (FRF.13), not tied to a specific manufacturer; applies to Frame Relay network equipment and carrier circuits

Monitoring Examples

No sample objects were captured for this entry, so no specific table names can be cited; based on the module description, a realistic scenario is an operator periodically reading service-level metric objects such as data delivery ratio and availability percentage for a given Frame Relay PVC to verify the carrier is meeting a contracted SLA, flagging a breach if delivery ratio drops below the agreed threshold.

What Can Be Monitored

  • data delivery ratio
  • frame delay
  • service availability percentage
  • SLA compliance metrics

How to Use in IPNetwork Monitor

Example using frsldPvcDataMissedPolls OID:

Select a device implementing FRSLD-MIB 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 frsldPvcDataMissedPolls into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of polls that have been determined to be missed. 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 Counter32-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.

RFC description

Defines Frame Relay service level management and performance metrics (RFC 3202).

Start monitoring Vendor-neutral Frame Relay network equipment/carrier circuit, any manufacturer (FRF.13 service levels) 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.
