Category: Quality of Service, Vendor: H3C/HH3C

Description: Provides enhanced class-based QoS policy and traffic-shaping statistics (version 2) on H3C network devices.

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 A3COM-HUAWEI-CBQOS2-MIB?

A3COM-HUAWEI-CBQOS2-MIB is a joint 3Com/H3C vendor MIB providing an enhanced, version-2 Class-Based QoS (CBQoS) implementation for configuring and monitoring traffic classification, policy behavior, and traffic-shaping/policing (CAR) on H3C network devices. It exposes a family of tables covering traffic classifier definitions, match-rule configuration, policy behavior actions, CAR (Committed Access Rate) rate-limiting configuration, and aggregative CAR settings applied across interfaces. Its monitoring value centers on QoS policy software status and running-state statistics: confirming which classifiers/match-rules/behaviors are applied to an interface and observing the associated traffic-shaping counters to detect a policy dropping or remarking more traffic than expected, which is a control-plane/software configuration health concern rather than physical hardware status. It is a self-contained enhancement of the vendor's own CBQoS MIB family (superseding an earlier CBQOS-MIB version), without strong dependency on external standard MIBs evident from the description. It is typically deployed on H3C/3Com switches and routers in enterprise or carrier networks needing granular class-based traffic engineering and rate limiting. Engineers can download the A3COM-HUAWEI-CBQOS2-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-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 switch/router
  • 3Com enterprise network device

Monitoring Examples

No sample objects were retained in the source data for this MIB beyond the module description, so a grounded polling example naming real objects cannot be constructed here; the description does name five tables (h3cCBQoSClassifierCfgInfoTable, h3cCBQoSMatchRuleCfgInfoTable, h3cCBQoSBehaviorCfgInfoTable, h3cCBQoSCarCfgInfoTable, h3cCBQoSAggregativeCarCfgInfoTable), and a realistic use would poll the CAR and aggregative CAR tables for drop/conform counters on a given interface to detect a policy that is rate-limiting traffic more aggressively than intended, but individual object-level names cannot be confirmed from this source.

What Can Be Monitored

  • traffic classifier configuration
  • match rule configuration
  • QoS behavior/policy actions
  • CAR rate-limit configuration
  • aggregative CAR statistics

How to Use in IPNetwork Monitor

Example using h3cCBQoSIfCbqDiscard OID:

Select an H3C/3Com router or switch 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.
