What Is E5-121-TRAPS-MIB?

E5-121-TRAPS-MIB defines the fault and event notification structures for the Calix E5-121 broadband access platform, a carrier access/aggregation device. It exposes an alarm table capturing the object class and instance identifiers responsible for each alarm along with an alarm type, mirroring the trap structure used on the sibling E5-111 platform. This is a faults/traps MIB directly supporting monitoring of hardware and software fault conditions on the device: each alarm entry identifies which managed object (e.g., a card, port, or service, via object class/instance) triggered the event, and of what type. It depends on the broader Calix E5-series MIB structure for the definitions of the objects referenced by class/instance, plus standard SNMP notification conventions. It is typically deployed in carrier/service-provider access networks to feed device fault events into an NMS for real-time alarm correlation. Network engineers evaluating or troubleshooting this functionality can download the E5-121-TRAPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in E5-121-TRAPS-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

  • Calix E5-121 access platform

Monitoring Examples

e5AlarmTable/e5AlarmEntry record e5AlarmObjectClass and up to eight instance identifiers (e5AlarmObjectInstance1 through e5AlarmObjectInstance8) pinpointing exactly which managed resource raised a condition, together with e5AlarmType classifying the fault. An NMS would subscribe to these traps to be alerted immediately when a fault occurs on the E5-121, then use the object class/instance fields to drill into the specific affected hardware component. This lets operators correlate incoming SNMP traps directly to physical resources without polling every object individually.

What Can Be Monitored

  • alarm/fault events
  • alarm object class
  • alarm object instance identifiers
  • alarm type classification
