H3C-VOICE-VLAN-MIB

Description: H3C MIB for Voice VLAN management automatically assigning IP phone traffic to a dedicated voice VLAN.

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.

H3C-VOICE-VLAN-MIB is an H3C (Hewlett-Packard/New H3C) enterprise MIB for managing the Voice VLAN feature on H3C LAN switch products, which automatically classifies detected IP phone traffic into a dedicated VLAN for QoS treatment. It exposes configuration-oriented data covering global and per-port voice VLAN enable state, OUI (vendor MAC prefix) matching rules used to detect phones, aging timers, and port operating modes. As a configuration/feature-control MIB, its monitoring value is primarily about verifying that the voice VLAN feature is correctly enabled and applied per port rather than hardware health; administrators use it to confirm phones are being detected and placed into the intended VLAN and that per-port voice VLAN state matches policy. It depends on underlying standard VLAN and interface indexing conventions (ifIndex from IF-MIB and dot1qVlan concepts from Q-BRIDGE-MIB) even though it defines its own proprietary objects. It is typically deployed on H3C/HPE Comware-based access switches in enterprise LANs carrying converged voice and data traffic, where H3C-VOICE-VLAN-MIB SNMP monitoring confirms phones are landing in the correct VLAN.

Since no sample objects were provided for this module, a realistic scenario is inferred from its stated purpose: an administrator would poll per-port voice VLAN enable/mode objects (indexed by ifIndex) to confirm a switch port feeding an IP phone has voice VLAN active, and check the OUI table entries to verify a new phone's MAC OUI is recognized. A port that fails to move into the voice VLAN despite voice VLAN being enabled would point to an OUI mismatch or misconfigured port mode.

H3C proprietary MIB for managing voice VLAN configurations on network switches, enabling prioritization of voice traffic for QoS and ensuring superior voice call quality.
