Description: Huawei QinQ (IEEE 802.1ad) MIB for managing double-tagged VLAN stacking, SVLAN/CVLAN mappings, and provider bridging.

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 HUAWEI-QINQ-MIB?

HUAWEI-QINQ-MIB is a Huawei enterprise MIB for managing QinQ (IEEE 802.1ad, VLAN stacking) on Huawei switches and routers, a technology that nests a service-provider VLAN tag (SVLAN) around a customer VLAN tag (CVLAN) to scale VLAN space in provider networks. It exposes configuration objects at both the system and interface level describing QinQ mode, SVLAN/CVLAN mapping tables, and provider-bridging behavior. From a monitoring perspective it is used to confirm that the correct QinQ mode and VLAN mapping are actually applied on each interface, verifying operational configuration state rather than hardware health, which helps catch VLAN stacking misconfigurations that would break service delivery. It relies on the IEEE 802.1ad/802.1Q VLAN tagging standards conceptually, though it is implemented as a Huawei-specific MIB alongside other hwDatacomm modules. It is deployed on Huawei carrier-class and enterprise switches used in metro Ethernet and provider-bridging network designs. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-QINQ-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-QINQ-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

  • Huawei enterprise/carrier switch
  • Huawei provider-bridging network equipment

Monitoring Examples

A typical structure would include an interface-indexed QinQ mode/mapping table (e.g., an hwQinQ*Table/Entry pattern) holding SVLAN and CVLAN identifiers per port. An administrator would poll such a table to verify that a given access port is correctly stacking a specific CVLAN inside the expected SVLAN, and an unexpected or missing mapping would reveal a provisioning error causing customer traffic to be dropped or misrouted.

What Can Be Monitored

  • QinQ operating mode
  • SVLAN to CVLAN mapping
  • per-interface VLAN stacking configuration
  • provider bridging status

How to Use in IPNetwork Monitor

Example using hwQinQSubIfStackingStatOutPackets OID:

Select a Huawei enterprise/carrier switch (802.1ad QinQ VLAN stacking) 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 hwQinQSubIfStackingStatOutPackets 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. It reports the total number of out packets of the sub interface. 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.
