HH3C-QINQ-MIB

Description: HH3C MIB for QinQ (802.1Q-in-802.1Q) double-tagging VLAN tunneling configuration on H3C switches.

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.

HH3C-QINQ-MIB is an H3C enterprise MIB for managing QinQ (802.1Q-in-802.1Q) double VLAN tagging, a technique used to tunnel customer VLAN traffic transparently across a service-provider network by adding an outer VLAN tag. Based on its description, it is expected to expose per-port or per-VLAN configuration for enabling QinQ tunneling and mapping outer-to-inner VLAN tags, though no sample objects were captured for this entry. Its monitoring relevance is configuration-status oriented, confirming QinQ tunneling is enabled on the correct ports and that outer tag assignment matches the service design, rather than hardware sensor data. It builds on the standard IEEE 802.1Q VLAN tagging model, adding a second, service-provider-facing tag layer beyond what standard Q-BRIDGE-MIB covers. It is typically deployed on H3C carrier-Ethernet or metro-access switches offering Layer 2 VPN transport for multiple customers over a shared VLAN infrastructure. Engineers can download the HH3C-QINQ-MIB file directly to load it into their MIB browser.

No sample objects were captured for this module, so specific object or table names cannot be confirmed here. Based on its purpose, an admin would typically check per-port QinQ enable status and outer VLAN tag assignment to confirm customer traffic is being correctly double-tagged for transport across the provider network, investigating if customer traffic mixes when tags are misassigned. This remains a general expectation rather than a concrete example grounded in named objects.
