Description: H3C MIB extending 802.11 WLAN configuration with additional security and radio management parameters.

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 H3C-DOT11-CFGEXT-MIB?

H3C-DOT11-CFGEXT-MIB is an H3C proprietary MIB extending the vendor's base 802.11 WLAN configuration MIB with load-balancing and related radio-management parameters for wireless access point/controller deployments. It exposes traffic-based and session-based load-balancing enable flags and thresholds, load-balancing gap timers, and radio-group tables used to group access point radios for balanced client distribution. This module is primarily a configuration/policy MIB rather than a hardware-fault MIB, but it lets an administrator monitor whether load-balancing features are active and correctly grouping radios, which indirectly reflects WLAN service health under client load. It builds on the IEEE 802.11 standard and is explicitly described as an extension of H3C's own base h3c-dot11-cfg MIB, so it depends on that companion module for foundational WLAN configuration objects. It is deployed on H3C wireless access controllers and access points in enterprise WLAN deployments. Engineers can download the H3C-DOT11-CFGEXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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
H3C wireless access point

Monitoring Examples

An operator would check h3cDot11LoadBalanceTrafficEnable and h3cDot11LoadBalanceSessionEnable to confirm load balancing is turned on, then poll h3cDot11LBRadioGroupTable/h3cDot11LBRadioGroupEntry to see which radios are grouped under a given h3cDot11LBRadioGroupId. Comparing live traffic against h3cDot11LBTrafficThresKbps and h3cDot11LoadBalanceTrafficThres reveals whether a radio group is being triggered to redirect clients due to congestion.

What Can Be Monitored

traffic-based load balancing enable state
session-based load balancing enable state
traffic/session load balancing thresholds
load balancing gap timers
radio group membership and description

OID symbolic	OID numeric	Type	Access	Description
h3cDot11CFGEXT	1.3.6.1.4.1.2011.10.2.75.6			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.
