Description: Defines extended 802.11 WLAN configuration objects supplementing the base CFG MIB on H3C wireless platforms.

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 A3COM-HUAWEI-DOT11-CFGEXT-MIB?

A3COM-HUAWEI-DOT11-CFGEXT-MIB is an H3C WLAN MIB that extends the base 802.11 configuration MIB with objects specifically for load-balancing traffic and client sessions across radios and access points. It exposes configuration state for traffic-based and session-based load balancing, including enable flags, thresholds, and gap parameters, plus grouping of radios for balancing purposes. Its monitoring value lies in verifying WLAN load-distribution health: administrators check whether load balancing is enabled and whether configured thresholds are being applied correctly, which indirectly affects client experience and radio congestion rather than exposing raw hardware sensors. As an extension module it explicitly depends on the companion base WLAN configuration MIB (h3c-dot11-cfg.mib) for the core 802.11 settings it supplements. It is deployed on H3C wireless access controllers managing multi-radio, multi-AP deployments where balancing client load across radios matters, and administrators can download the A3COM-HUAWEI-DOT11-CFGEXT-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-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.

H3C wireless access controllers and access points

Monitoring Examples

An admin would check h3cDot11LoadBalanceTrafficEnable and h3cDot11LoadBalanceSessionEnable to confirm load balancing is active, then compare live conditions against h3cDot11LoadBalanceTrafficThres and h3cDot11LoadBalanceSessionThres to see how close a radio group is to triggering rebalancing. The h3cDot11LBRadioGroupTable (entries keyed by h3cDot11LBRadioGroupId, described via h3cDot11LBRadioGroupDesc) shows which radios are grouped together for balancing purposes. Persistent breaches of h3cDot11LBTrafficThresKbps would suggest a radio group is overloaded and needs additional capacity or retuned thresholds.

What Can Be Monitored

load-balance enable status (traffic/session)
traffic load-balance threshold
session load-balance threshold
radio group membership
load-balance gap parameters

h3cDot11CFGEXT	1.3.6.1.4.1.43.45.1.10.2.75.6			This MIB provides information for WLAN configuration extended. The h3c-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.
