Description: Monitors 802.11 security associations, cipher suites, and key negotiation status 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 A3COM-HUAWEI-DOT11-SA-MIB?

Although the internal short description references security associations, the module_desc and object names in A3COM-HUAWEI-DOT11-SA-MIB (SA = Spectrum Analysis) show it actually governs RF spectrum-analysis capability on H3C/Huawei wireless access points. It exposes per-radio spectrum-analysis configuration, interference-detection trap enables and thresholds, driven radio-resource-management (RRM) settings, and raw FFT (Fast Fourier Transform) spectral scan data. This is squarely a hardware/RF-diagnostic monitoring MIB: it lets an operator see whether spectrum analysis is enabled on a radio, whether interference or air-quality traps have fired, and inspect raw FFT scan results used to identify sources of RF interference affecting the wireless hardware. It is a vendor-specific extension layered on 802.11 concepts rather than deriving from a single IETF RFC. Typical deployment is on enterprise H3C/Huawei access points performing continuous RF spectrum monitoring to diagnose Wi-Fi interference and channel-quality issues. Engineers can download the A3COM-HUAWEI-DOT11-SA-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DOT11-SA-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/Huawei wireless access points

Monitoring Examples

An admin would enable h3cDot11SaEnable on a radio and poll h3cDot11SaCfgTable (via h3cDot11SaCfgRadioType) to confirm spectrum analysis is active, then watch h3cDot11SaTrapAQEnable and h3cDot11SaTrapAQThreshold for air-quality traps indicating degraded RF conditions. Pulling raw scan results from h3cDot11SaRtFFTDataTable would show which frequencies within the channel are experiencing the strongest interference, and h3cDot11SaDrivenRRMEnable indicates whether the AP automatically re-selects channels in response to detected interference.

What Can Be Monitored

spectrum analysis enable status per radio
interference/air-quality trap thresholds
FFT spectral scan data
RF-driven RRM (radio resource management) status

OID symbolic	OID numeric	Type	Access	Description
h3cDot11Sa	1.3.6.1.4.1.43.45.1.10.2.75.13			This MIB module provides spectrum analysis information. The initial revision of this MIB module. The spectrum analysis module on APs is able to examine the radio frequency (RF) environment in which the Wi-Fi network is operating, identify interference and classify its sources. An analysis of the results can then be used to quickly isolate issues with packet transmission, channel quality, and traffic congestion caused by contention with other devices operating in the same band or channel.
