Description: H3C MIB for Route Change Reporting (RCR) notifying management systems of routing table modifications.

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-RCR-MIB?

H3C-RCR-MIB is an H3C private MIB supporting Resilient Controllable Routing (RCR), a feature that dynamically adjusts outbound traffic across external interfaces based on measured performance and load, and reports routing table changes to the management station. Although no sample objects were supplied, based on its description it would expose objects/notifications reporting route additions, deletions, and interface-selection decisions made by the RCR feature, alongside performance/load metrics per external interface used for that decision-making. This makes it a performance and fault/event MIB: it lets an operator monitor per-interface load/performance and be notified when RCR changes the routing table or reselects an optimal exit interface, which functions as software-level operational status rather than chassis hardware health. It builds on standard IP routing table concepts (akin to ipCidrRouteTable) that RCR modifies dynamically, and depends on the router's underlying routing infrastructure. It is typically deployed on H3C routers at network edges with multiple ISP/WAN uplinks, used for outbound traffic load balancing and failover. Engineers can download the H3C-RCR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-RCR-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 with multiple external/WAN interfaces

Monitoring Examples

No sample objects were provided for this module, so specific table names cannot be confirmed from source; based on the description, a realistic scenario would be receiving RCR route-change notifications and correlating them with per-interface performance/load metrics to understand why traffic was shifted from one external interface to another, revealing a degraded or congested WAN uplink.

What Can Be Monitored

routing table change events
per-interface performance/load metrics
selected optimal external interface

How to Use in IPNetwork Monitor

Example using h3cRcrMRAllMaxUsedBandRate OID:

Select an H3C router with multiple external/WAN interface (Resilient Controllable Routing) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type h3cRcrMRAllMaxUsedBandRate into the Find box to locate it in the OID tree, then select it and click OK. The max used band rate of all external interfaces on member router-devices(MRs) which are controlled by RCR. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
h3cRcr	1.3.6.1.4.1.2011.10.2.48			This MIB is applicable to router-devices. It's made for RCR (Resilient Controllable Routing). RCR provides an effective resolution which can dynamically auto-adjust outbound traffic to the optimal external interface by monitoring the performance and traffic load of each external interface. It provides the functions of intelligentized traffic load distribution and the optimal external interface selection. This can optimally utilize the external interfaces. Furthermore, RCR realized the function which can select the optimal external interface based on different classes of operation flow.
