Description: Monitors 802.11 client roaming events, inter-AP handoff statistics, and roaming policies on H3C WLAN controllers.

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-ROAM-MIB?

A3COM-HUAWEI-DOT11-ROAM-MIB is an H3C/3Com wireless LAN controller MIB covering IEEE 802.11 client roaming, specifically the mobility groups used to coordinate handoff of wireless clients between access points (APs) managed by an access controller (AC). It models mobility group membership, tunnel type, source address, and authentication parameters, plus roaming configuration, status, and statistics groups. Its monitoring value is on the software/service side: administrators use it to confirm mobility groups are correctly formed and enabled, member ACs are reachable, and roaming events are succeeding rather than causing dropped wireless sessions. It builds on IEEE 802.11 wireless LAN concepts (AP, AC, BSS) and is meant to be used alongside the vendor's broader WLAN AP/AC management MIBs. It is deployed in enterprise campus WLAN environments using H3C wireless controllers to manage seamless client roaming across multiple APs, where A3COM-HUAWEI-DOT11-ROAM-MIB SNMP monitoring helps confirm mobility groups remain correctly formed and reachable.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DOT11-ROAM-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/3Com wireless LAN controllers and access points

Monitoring Examples

An administrator walks h3cDot11MobGrpTable/h3cDot11MobGrpEntry to check h3cDot11MobGrpEnable and h3cDot11MobGrpRowStatus, confirming a mobility group is active and correctly provisioned with h3cDot11MobGrpAuthMode/h3cDot11MobGrpAuthKey matching across controllers. h3cDot11MobGrpMemberTable/h3cDot11MobGrpMemberEntry lists member AC IP addresses (h3cDot11MobGrpMemberIpAddr), and a missing or unreachable member here would explain clients failing to roam seamlessly between AP coverage areas served by different controllers. The h3cDot11RoamStatisGroup statistics would be checked to spot an abnormal rate of failed roam attempts.

What Can Be Monitored

mobility group membership
mobility group enable/row status
inter-controller authentication config
member AC reachability
roaming statistics
roam success/failure rate

How to Use in IPNetwork Monitor

Example using h3cDot11IntraACRoamingSuccCnt2 OID:

Select an H3C wireless controller or access point 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 h3cDot11IntraACRoamingSuccCnt2 into the Find box to locate it in the OID tree, then select it and click OK. Represents the count of client successfully roam Intra-AC in Counter32. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
h3cDot11ROAM	1.3.6.1.4.1.43.45.1.10.2.75.10			This MIB provides information about WLAN roaming configuration. 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. 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. HA The AC to which a wireless station is connected by associating with an AP for the first time is the HA of the station. FA An AC that is other than the HA and to which a station is currently connected is an FA of the station. Fast-roam capable station A wireless station which directly associates to a fast-roam service (rsn+dot1X) with one AC for the first time. Roam-out station A wireless station which has associated with an AC other than the HA in the mobility-group is referred to as a roam-out station at its HA. Roam-in station A wireless station which has associated with an AC other than the HA in the mobility-group is referred to as a roam-in station at the FA. Intra-AC roaming A procedure where a wireless station roams from one AP to another AP, which are connected to the same AC. Inter-AC roaming A procedure where a wireless station roams from one AP to another AP, which are connected to different ACs. Inter-AC fast roaming capability If a station uses 802.1x (RSN) authentication through negotiation, this station has inter-AC fast roaming capability. WLAN-tunnel One type of layer 2 interface which is bound with an IACTP data tunnel and used to tunnel unicast/broadcast frames between ACs.
