Description: Provides extended 802.11 configuration objects for H3C APs including band steering and load balancing settings.

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-CFGEXT-MIB?

HH3C-DOT11-CFGEXT-MIB is an H3C enterprise MIB extending 802.11 WLAN configuration on H3C wireless access controllers (AC) and access points (AP), specifically covering band/load-balancing features that distribute client sessions across radios or APs. It exposes configuration objects for traffic-based and session-based load balancing (enable flags, thresholds, gap/hysteresis values in kbps or session counts) and radio-group definitions used to scope balancing policies. Monitoring-wise it is mainly a software/feature-configuration MIB: polling it verifies whether load balancing is enabled and which thresholds are active, helping diagnose uneven AP/radio utilization or client experience issues caused by misconfigured or disabled load balancing. It explicitly depends on the base hh3c-dot11-cfg MIB for core WLAN configuration, as noted in its description. Typical deployment is on H3C wireless controllers managing fleets of APs in enterprise Wi-Fi deployments, and administrators can download the HH3C-DOT11-CFGEXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-DOT11-CFGEXT-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 wireless access controller (AC)
H3C 802.11 access point (AP)

Monitoring Examples

An admin would check hh3cDot11LoadBalanceTrafficEnable and hh3cDot11LoadBalanceTrafficThres to confirm traffic-based load balancing is active and its kbps threshold, alongside hh3cDot11LoadBalanceSessionEnable/hh3cDot11LoadBalanceSessionThres for session-count balancing. Reviewing hh3cDot11LBRadioGroupTable (via hh3cDot11LBRadioGroupId/hh3cDot11LBRadioGroupDesc) would reveal which radios are grouped for balancing, and a disabled setting here could explain why some APs are overloaded while neighboring APs sit idle.

What Can Be Monitored

traffic-based load balance enable/threshold
session-based load balance enable/threshold
load balance hysteresis gap
radio group membership for load balancing

OID symbolic	OID numeric	Type	Access	Description
hh3cDot11CFGEXT	1.3.6.1.4.1.25506.2.75.6			This MIB provides information for WLAN configuration extended. The hh3c-dot11-cfg.mib define MIB objects for WLAN basic configuration, while this MIB will define MIB objects for load balance these kinds feature. GLOSSARY IEEE 802.11 Standard to encourage interoperability among wireless networking equipment. Access point (AP) Transmitter/receiver (transceiver) device that commonly connects and transports data between a wireless network and a wired network. Access control (AC) To control and manage multi-APs, it will bridge wireless and wired network. Fat AP Applied in the home, SOHO and so on, and it could work independently without help from AC. Fit AP Applied in the enterprise environment, it will work under the control and management from AC. Control And Provisioning of Wireless Access Points Protocol The short name of protocol is CAPWAP. AC will control and manage AP by CAPWAP tunnel protocol defined by IETF. Also, a data tunnel will be set up between AC and AP. BSS IEEE 802.11 Basic Service Set (Radio Cell). The BSS of an AP comprises of the stations directly associating with the AP. Radio The chip set to receive and send wireless signal. Association The service used to establish access point or station mapping and enable station invocation of the distribution system services. (Wireless clients attempt to connect to access points.) Basic Rate A data rate that is mandatory for client devices to support in order for them to achieve successful association. MSDU MAC Service Data Unit, it is frame format defined by 802.11. TU It is 1,024 microseconds (ms), which is about 1 millisecond. AKM The authentication and key management method defined by 802.11i, and which includes 802.1x and pre-shared key.
