Description: HP Networking ICF SNMP MIB for extended WLAN configuration including captive portal and advanced access control on HP 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 HPN-ICF-DOT11-WLANEXT-MIB?

HPN-ICF-DOT11-WLANEXT-MIB is an HP Networking (Comware/H3C ICF) vendor MIB that extends standard 802.11 wireless LAN management with additional RF and QoS statistics for wireless access points and controllers. It exposes per-radio and per-AP data covering RF signal quality statistics and QoS-related traffic statistics, layered on top of general WLAN configuration concepts like access points, radios, and 802.11e QoS. For hardware/software status monitoring, this MIB is chiefly useful for tracking radio-frequency health (average, minimum, and maximum signal strength over a measurement interval) and QoS traffic behavior per radio, which together reveal RF interference, coverage gaps, or overloaded radios well before end users report connectivity complaints. It is an extension built on top of standard IEEE 802.11/802.11e concepts and would typically be used alongside a base WLAN or AP-management MIB rather than standing alone. Typical deployment is on HP/H3C enterprise wireless controllers or autonomous access points serving corporate or campus Wi-Fi networks. Engineers can download the HPN-ICF-DOT11-WLANEXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-DOT11-WLANEXT-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

HP/H3C Comware wireless access point
HP/H3C wireless LAN controller

Monitoring Examples

An administrator would poll hpnicfDot11RFSignalStatisTable, indexed by hpnicfDot11RFAPID and hpnicfDot11RFRadioID, and inspect hpnicfDot11RFAverageSignalStrength, hpnicfDot11RFMaxSignalStrength, and hpnicfDot11RFMinSignalStrength over hpnicfDot11RFSignalStatisInterv to detect radios experiencing degraded or highly variable RF conditions. Similarly, hpnicfDot11QosStatisTable (keyed by hpnicfDot11QosAPID/hpnicfDot11QosRadioID) would be polled to observe QoS traffic statistics per radio, revealing which access points are under heavy load. A sustained drop in average signal strength on a specific hpnicfDot11RFRadioID would flag a physical RF problem such as antenna failure or new interference source.

What Can Be Monitored

average/min/max RF signal strength per radio
signal statistics collection interval
per-radio QoS traffic statistics
access point and radio identifiers

How to Use in IPNetwork Monitor

Example using hpnicfDot11AcDropFrameCnt OID:

Select an HP/H3C Comware wireless access point/controller (RF/QoS extended stats) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hpnicfDot11AcDropFrameCnt into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of dropped frames in a minute for one specific access category because of full queue. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpnicfDot11WLANEXT	1.3.6.1.4.1.11.2.14.11.15.2.75.7			This MIB provides more information for WLAN network. GLOSSARY IEEE 802.11 Standard to encourage interoperability among wireless networking equipment. IEEE 802.11e Standard to define the MAC procedures to support LAN applications with Quality of Service (QoS) requirements, including the transport of voice, audio and video over IEEE 802.11 wireless LANs. 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. Radio The chip set to receive and send wireless signal. Fat AP Applied in the home, SOHO and so on, and it could independently work 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. Basic Service Set The IEEE 802.11 BSS of an AP comprises of the stations directly associating with the AP. It will be identified by BSSID.
