Description: HH3C MIB for Redundant Default Device Configuration (RDDC) managing dual-device redundancy on H3C networks.

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 HH3C-RDDC-MIB?

HH3C-RDDC-MIB manages Redundant Default Device Configuration (RDDC) groups, an H3C high-availability feature that keeps data and control planes running with minimal disruption when a node in an IRF (Intelligent Resilient Framework) fabric fails. It exposes redundancy group membership, preemption timers (configured and remaining), hold timers, and per-node group association for the devices participating in a redundancy group. This is a fault/failover monitoring MIB at its core: tracking preemption/hold-time countdowns and node membership reveals whether a failover has occurred, whether preemption back to a preferred node is pending, and whether a node has unexpectedly dropped out of the group. It works in conjunction with H3C's IRF stacking/clustering technology, on top of which the redundancy group model is built. It is deployed on H3C switches and routers configured in IRF clusters where continuous service during a node failure is required, such as core network or data center aggregation layers. Engineers can download the HH3C-RDDC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-RDDC-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 IRF-clustered switch/router

Monitoring Examples

An administrator would poll hh3cRddcTable for hh3cRddcPreempTimeRemain and hh3cRddcHoldTimeRemain against a group identified by hh3cRddcGroupIdx/hh3cRddcGroupName to see whether a failover is active and when preemption back to the primary node will occur. Checking hh3cRddcNodeTable for a missing hh3cRddcNodeId under a given hh3cRddcNodeGroupIdx would reveal that a redundancy group member has dropped out, likely due to a node failure in the IRF fabric.

What Can Be Monitored

redundancy group membership
preemption time remaining
hold time remaining
per-node group association

OID symbolic	OID numeric	Type	Access	Description
hh3cRddc	1.3.6.1.4.1.25506.2.151			Redundancy group is concerned with ensuring minimal disruption to data and control planes in case of a failover. If one of the group-node in an IRF fails, the other group-node in the IRF takes over the function of the failed group-node with minimal service interruption. This module defines the objects pertaining to redundancy group(RDDC).
