Description: Service Level Agreement MIB for DL devices providing objects to configure, measure, and report on SLA metrics.

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 DL-SLA-MIB?

This is a Digital Link (DL) enterprise MIB for configuring and measuring Service Level Agreement (SLA) metrics on WAN access devices, particularly over Frame Relay DLCIs. It exposes objects for sampling periods, thresholds for frame delivery/discard rates, delay measurement configuration, and per-DLCI committed information rate settings. Its monitoring focus is performance and configuration status: tracking whether frame delivery ratio (FDR), discard/drop ratio (DDR), and delay measurements stay within configured thresholds, which reveals WAN circuit congestion or degradation rather than raw device hardware faults. It likely builds on Frame Relay concepts standardized in FRAME-RELAY-DTE-MIB for the underlying DLCI and circuit model. It is typically deployed on Digital Link WAN units carrying Frame Relay traffic where carriers or enterprises need to verify contracted SLA performance is being met. Engineers can download the DL-SLA-MIB file directly to load it into their MIB browser.

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

Digital Link Frame Relay WAN access unit

Monitoring Examples

An administrator can poll unitSamplingPeriodForFDR-DDR and unitThresholdForFDR/unitThresholdForDDR to confirm frame delivery and discard ratio thresholds are configured as expected, then compare live measurements against configurationPerDLCITable/configurationPerDLCIEntry (indexed by configurationPerDLCITableIndex) to check commitedInformationRatePerDLCI per virtual circuit. A DLCI whose measured delay or discard rate exceeds its configured threshold would indicate the WAN link is failing to meet its committed SLA, prompting escalation to the carrier.

What Can Be Monitored

frame delivery ratio (FDR)
frame discard/drop ratio (DDR)
delay measurement per DLCI
committed information rate per DLCI
