Description: HH3C version 2 MIB for QinQ double-tagging VLAN tunneling with enhanced configuration options.
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 HH3C-QINQV2-MIB?
HH3C-QINQV2-MIB is an H3C (Hangzhou H3C Technologies) enterprise MIB providing version-2 configuration for 802.1 QinQ double-tagging VLAN tunneling, rooted under hh3cCommon.hh3cQinQv2 (hh3cCommon 137). It exposes global scalar controls hh3cQinQv2ServiceTPID and hh3cQinQv2CustomerTPID for the TPID values used on service and customer VLAN tags device-wide, and a per-interface hh3cQinQv2IfCfgTable (indexed by ifIndex) that enables/disables QinQ on the port (hh3cQinQv2IfState), overrides the service/customer TPID per interface, and defines a transparent-VLAN bitmap (hh3cQinQv2IfTransVlanList) specifying which VLANs pass through untouched by QinQ tagging. This gives operators visibility into whether QinQ tunneling is correctly enabled per port and whether TPID values and transparent-VLAN exclusions match the intended service-provider VLAN design, which matters for diagnosing tag-stripping or double-tagging mismatches between customer and provider edge devices. It depends on HH3C-OID-MIB for its enterprise OID anchor and IF-MIB's ifIndex for per-port indexing, and is deployed on H3C switches acting as provider-edge devices in metro Ethernet or VLAN-tunneling deployments. Teams provisioning QinQ on H3C gear commonly pull an HH3C-QINQV2-MIB download to confirm per-port TPID overrides.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-QINQV2-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 (Hangzhou H3C Technologies) switches supporting 802.1 QinQ v2
Monitoring Examples
An operator polls hh3cQinQv2IfCfgTable's hh3cQinQv2IfState and hh3cQinQv2IfServiceTPID for a given ifIndex to confirm QinQ is enabled with the expected TPID on a provider-facing port, then checks hh3cQinQv2IfTransVlanList to verify the transparent VLAN bitmap matches which customer VLANs should bypass tagging; a port showing QinQ disabled or an unexpected TPID would explain double-tagged frames being rejected or misclassified downstream.
What Can Be Monitored
- global service/customer TPID configuration
- per-interface QinQ enable state
- per-interface TPID overrides
- transparent VLAN bitmap per interface
