Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is ADTRAN-MEF-PER-EVC-PERF-HISTORY-MIB?
This is an ADTRAN AOS (Adtran Operating System) enterprise MIB implementing MEF (Metro Ethernet Forum) performance history statistics per Ethernet Virtual Connection (EVC) on ADTRAN carrier Ethernet devices. It exposes historical and current-interval performance counters -- ingress/egress green (compliant) frame and octet counts, frame discards, and interval-validity flags -- bucketed into 15-minute collection windows. Although its focus is traffic performance rather than classic hardware health, it is key to monitoring the operational status of Carrier Ethernet services, revealing service degradation, discards, and interval data-collection integrity issues rather than CPU/temperature faults. It depends conceptually on MEF EVC performance-monitoring standards and complements ADTRAN's other AOS MIBs rather than the standard IETF Interfaces MIB. Typical deployment is on ADTRAN AOS-based carrier Ethernet access/aggregation devices at service-provider demarcation points, used for SLA verification and Ethernet service assurance. Engineers can download the ADTRAN-MEF-PER-EVC-PERF-HISTORY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ADTRAN-MEF-PER-EVC-PERF-HISTORY-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
- ADTRAN carrier Ethernet access devices
Monitoring Examples
A service provider polls adMefPerEvcPhCurTable (entries in adMefPerEvcPhCurEntry, keyed by adMefPerEvcPhCurEvcNameFixedLen) to check adMefPerEvcPhCurIngressGreenFrameDiscards15Min and adMefPerEvcPhCurEgressGreenFrameDiscards15Min for a customer's EVC. Rising discard counts alongside a shrinking adMefPerEvcPhCurValidIntervals15Min (or a growing adMefPerEvcPhCurInvalidIntervals15Min) would indicate the EVC is exceeding its committed bandwidth or experiencing measurement gaps. Frame/octet counters such as adMefPerEvcPhCurIngressGreenOctets15Min are compared against contracted rates to verify SLA compliance.
What Can Be Monitored
- ingress/egress green frame counts
- ingress/egress green octet counts
- ingress/egress frame discards
- 15-minute interval elapsed time
- valid/invalid interval counts
- per-EVC performance history
