Category: Network Monitoring (RMON), Vendor: H3C/HH3C

Description: Monitors Deep Application Recognition (DAR) protocol identification rules and traffic statistics on H3C 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-DAR-MIB?

This is a 3Com-Huawei (H3C) joint-venture vendor MIB for Deep Application Recognition (DAR), a deep-packet-inspection feature that classifies traffic by application protocol on H3C routers and switches. It exposes per-protocol traffic statistics — packet and byte counts, and current/maximum bit rates for both directions — for each recognized application. Its monitoring focus is software-based network/application visibility rather than physical hardware: sustained bit rates on an unexpected protocol reveal unplanned bandwidth consumption, useful for capacity planning and detecting anomalous application traffic. It depends on an underlying DPI classification engine to identify protocols and likely complements the standard interface MIB for per-interface context. It is deployed on H3C (3Com/Huawei) routers and switches doing application-aware traffic monitoring or QoS enforcement in enterprise networks. Engineers can download the A3COM-HUAWEI-DAR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DAR-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 (3Com/Huawei) router or switch with DPI/DAR support

Monitoring Examples

An admin polls h3cDarStatisticsTable, keyed by h3cDarStatisticsProtocolID, to see h3cDarStatisticsProtocolName alongside h3cDarStatisticsInBitRate and h3cDarStatisticsOutBitRate for each recognized application — a sustained h3cDarStatisticsInBitRate approaching h3cDarStatisticsMaxInBitRate for an unexpected protocol (e.g., P2P or streaming) signals unplanned bandwidth consumption. Comparing h3cDarStatisticsInPkts/InBytes against OutPkts/OutBytes over time helps identify asymmetric or anomalous traffic patterns for a given application on the device.

per-protocol packet/byte counts
per-protocol input/output bit rate
maximum observed bit rate per protocol

How to Use in IPNetwork Monitor

Example using h3cDarStatisticsInPkts OID:

Select an H3C 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 h3cDarStatisticsInPkts 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 incoming packets of the specific protocol. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
