What Is A3COM-HUAWEI-E1T1VI-MIB?
A3COM-HUAWEI-E1T1VI-MIB is a joint 3Com/Huawei (H3C) enterprise MIB that manages E1/T1 voice interface configuration on H3C network devices, specifically covering data not addressed by the standard RFC 1213/RFC 2233 interface MIBs. It belongs to the voice/TDM interface technology area and exposes timeslot-level configuration and usage data via a table of E1/T1 voice interfaces. Its monitoring value is in tracking DS0 timeslot utilization and trap-driven fault reporting — specifically the ratio of timeslots in use versus total capacity, and notifications when timeslot state changes occur — which helps detect voice trunk exhaustion or unexpected channel state changes on the interface. It explicitly extends and complements RFC 1213 (MIB-II) and RFC 2233 (ifMIB) rather than duplicating them. Typical deployment context is H3C/3Com routers and gateways carrying E1/T1 voice trunks in enterprise or carrier voice-over-TDM deployments. Engineers can download the A3COM-HUAWEI-E1T1VI-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-E1T1VI-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
- H3C/3Com router or voice gateway with E1/T1 interfaces
Monitoring Examples
An administrator walks h3cE1T1VITable/h3cE1T1VIEntry to read h3cE1T1VIUsingTimeslots and h3cE1T1VIUsingTimeslotsRatio for each E1/T1 voice interface, watching for a ratio approaching 100% as a sign of trunk capacity exhaustion during peak call volume. Enabling h3cE1T1VITrapTimeSlotEnable causes the device to send notifications (h3cE1T1VINotifications) when timeslot usage state changes, letting an NMS alert on sudden drops in available channels without continuous polling.
What Can Be Monitored
- timeslots in use per E1/T1 interface
- timeslot usage ratio
- timeslot state change traps
