Description: The second version of the H3C traffic mirroring MIB, covering port-based and flow-based traffic monitoring along with copy policies.
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 H3C-TRNG2-MIB?
H3C-TRNG2-MIB is an H3C proprietary MIB for configuring absolute and periodic time ranges on the device — reusable time-window definitions used to schedule when a feature such as an ACL or QoS policy is active. Its actual module description and sample objects (time-range name/index tables with absolute start/end times) show it manages named time-range definitions rather than traffic mirroring. This is a configuration-status MIB rather than a hardware/performance monitoring one: administrators use it to confirm a named time range is currently valid (active) and that its absolute start/end timestamps are correctly set, which matters for verifying whether a time-based access or QoS policy is actually in effect right now. It has no strong dependency on other MIBs, functioning as a standalone scheduling primitive referenced by other H3C feature MIBs (such as ACL or QoS MIBs) that apply time ranges. It's deployed on H3C routers and switches wherever administrators use time-based ACLs or policies that should only apply during specific hours or dates. Engineers can download the H3C-TRNG2-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-TRNG2-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 routers
- H3C switches
Monitoring Examples
An admin would check h3cTrangeCreateTimerangeTable/h3cTrangeCreateTimerangeEntry (keyed by h3cTrangeIndex) for a given h3cTrangeName to see h3cTrangeValidFlag, confirming whether that time range is currently active. Drilling into h3cTrangeAbsoluteTable/h3cTrangeAbsoluteEntry (via h3cTrangeAbsoluteNameIndex and h3cTrangeAbsoluteSubIndex) reveals the exact h3cTrangeAbsoluteStartTime and h3cTrangeAbsoluteEndTime, useful for confirming why a time-based ACL unexpectedly became active or inactive. h3cTrangeCreateRowStatus would show whether a time-range entry is active or still being provisioned.
What Can Be Monitored
- time range validity/active state
- absolute start/end time per range
- time range row/provisioning status
- named time range index mapping
