Description: Manages 802.11e/WMM Quality of Service parameters and traffic prioritization on H3C wireless devices.

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-DOT11-QOS-MIB?

HH3C-DOT11-QOS-MIB manages IEEE 802.11e/WMM (Wi-Fi Multimedia) Quality of Service parameters on H3C wireless access points/controllers, controlling how radios prioritize voice, video, and data traffic. It exposes per-radio WMM enable/configuration objects, EDCA (Enhanced Distributed Channel Access) parameter tables per access category, and admission-control (CAC) policy and channel-utilization objects. Monitoring focus is on radio-level software configuration and load: whether WMM/EDCA is enabled per radio, current channel-utilization value, and admitted user count under CAC policy, revealing RF congestion or admission-control throttling rather than physical hardware faults. It depends on the base IEEE 802.11 wireless LAN standard and typically sits alongside vendor radio/interface MIBs for the same access points. It is deployed on H3C wireless controllers/APs in enterprise WLAN deployments carrying latency-sensitive voice/video traffic requiring QoS differentiation. Engineers can download the HH3C-DOT11-QOS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-DOT11-QOS-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.

Monitoring Examples

hh3cDot11RadioWmmCfgTable/hh3cDot11RadioWmmCfgEntry show hh3cDot11RadioWmmEnabled and hh3cDot11RadioCacChlUtlValue per hh3cDot11WmmRadioIndex, letting an admin see when channel utilization approaches the hh3cDot11RadioCacPolicy threshold and new voice calls start being blocked via hh3cDot11RadioCacUserNum limits. hh3cDot11RadioWmmEdcaCfgTable/hh3cDot11RadioWmmEdcaCfgEntry expose per-access-category hh3cDot11RadioWmmAifsn tuning, useful for confirming EDCA parameters match the intended voice/video prioritization.

hh3cDot11QoS	1.3.6.1.4.1.25506.2.75.9			This MIB provides information about WLAN QoS configuration. GLOSSARY IEEE 802.11 Standard to encourage interoperability among wireless networking equipment. WMM WMM is a wireless QoS protocol designed to preferentially transmit packets with high priority, thus guaranteeing better QoS services for voice and video applications in a wireless network. EDCA Enhanced distributed channel access (EDCA) is a channel contention mechanism designed by WMM to preferentially transmit packets with high priority and allocate more bandwidth to such packets. AC Access category (AC), is used for channel contention. WMM defines four access categories; they are AC-VO (voice), AC-VI (video), AC-BE (best-effort), and AC-BK (background) in the descending order of priority. When contending for a channel, a high-priority AC preempts a low-priority AC. CAC Connection admission control (CAC) limits the number of clients that are using high-priority ACs (AC-VO and AC-VI) to guarantee sufficient bandwidth for existing high-priority traffic. U-APSD Unscheduled automatic power-save delivery (U-APSD) is a new power saving mechanism defined by WMM to enhance the power saving capability of clients. SVP SpectraLink voice priority (SVP) is a voice priority protocol designed by the Spectralink company to guarantee QoS for voice traffic.
