Description: H3C MIB for Class-Based Quality of Service (CBQoS) version 2, managing policy maps, class maps, and traffic statistics.

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-CBQOS2-MIB?

H3C-CBQOS2-MIB is an H3C-specific MIB (version 2) for managing and monitoring the Class-Based Quality of Service (CB-QoS) feature on H3C switches and routers, covering traffic classification, behavior policies, and rate-limiting (Committed Access Rate, CAR). Per its own description it is built around a family of configuration tables — classifier, match-rule, behavior, CAR, and aggregative-CAR configuration tables — that define how traffic is classified and treated, plus associated objects for monitoring running QoS state. This is a configuration-and-performance MIB rather than a hardware-health one: it lets operators verify which QoS policies are applied and track class-based traffic-shaping/policing behavior on interfaces. There is no explicit external MIB dependency stated, though it logically pairs with standard interface (IF-MIB) indexing since QoS policies attach to interfaces. It is typically deployed on H3C enterprise/campus/data-center switches and routers wherever administrators need to enforce and verify differentiated QoS treatment for voice, video, or business-critical traffic classes. Engineers can download the H3C-CBQOS2-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-CBQOS2-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 switches and routers

Monitoring Examples

No concrete sample object names were provided for this module (sample_objects is empty), so a specific polling scenario cannot be grounded in real object names; the module description does confirm the presence of h3cCBQoSClassifierCfgInfoTable, h3cCBQoSMatchRuleCfgInfoTable, h3cCBQoSBehaviorCfgInfoTable, h3cCBQoSCarCfgInfoTable, and h3cCBQoSAggregativeCarCfgInfoTable as its core configuration tables. In practice an operator would poll these tables per interface to confirm the correct classifier and CAR policy is bound and to watch for policy mismatches after a configuration change.

What Can Be Monitored

  • traffic classifier configuration
  • match-rule configuration
  • traffic behavior/policy configuration
  • CAR (rate-limit) configuration
  • aggregative CAR configuration

How to Use in IPNetwork Monitor

Example using h3cCBQoSIfCbqDiscard OID:

Select an H3C switch/router (Class-Based QoS) 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 h3cCBQoSIfCbqDiscard into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of discarded packets which couldn't be enqueued. 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 a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
