TPLINK-VOICEVLAN-MIB

Description: Manages TP-Link switch voice VLAN configuration for automatic IP phone VLAN assignment.

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.

TPLINK-VOICEVLAN-MIB is a TP-Link vendor-specific MIB for configuring Voice VLAN on managed switches, a feature that automatically classifies traffic from recognized IP phones (via MAC OUI matching) into a dedicated voice VLAN with appropriate QoS priority. Configuration objects include the voice VLAN ID, OUI table entries used for phone detection, aging time, and per-port voice-VLAN mode. Its monitoring value is confirming that phone traffic is actually being classified and prioritized correctly; a phone not appearing in the OUI-matched state on its port would explain poor call quality from a lack of prioritization. It's a TP-Link-specific convenience feature layered on standard 802.1Q VLAN tagging and QoS mechanisms rather than an IETF standard itself. It's deployed on TP-Link managed switches in offices using VoIP handsets alongside data devices on the same access port. Engineers can download the TPLINK-VOICEVLAN-MIB file directly to load it into their MIB browser.

An administrator checks the voice VLAN OUI table to confirm a deployed phone vendor's MAC prefix is registered, then verifies the per-port voice-VLAN mode (auto/manual) on an access port to confirm the connected phone was automatically placed into the voice VLAN. If a phone's port still shows the default data-VLAN mode, it points to an OUI mismatch or the port's voice-VLAN feature being disabled, either of which would degrade call audio quality from lack of priority queuing.

Manages Voice VLAN configuration on TP-Link managed switches. Controls prioritization of voice traffic using VLAN tagging and 802.1p priority, supporting both manual and automatic voice endpoint discovery modes.
