Description: Manages 802.11 client roaming events, fast BSS transition, and inter-AC roaming statistics on H3C WLANs.

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 HH3C-DOT11-ROAM-MIB?

HH3C-DOT11-ROAM-MIB is an H3C proprietary MIB for wireless LAN controller (AC) environments, managing 802.11 client roaming behavior across access points and mobility groups, including inter-AC roaming and fast BSS transition setups. It exposes mobility group configuration (tunnel type, source IP, authentication mode/key) and mobility group membership tables identifying peer ACs participating in seamless roaming. As a monitoring MIB, it is primarily software/service-status focused: hh3cDot11MobGrpEnable and hh3cDot11RoamStatusGroup let an operator confirm the roaming/mobility feature is active and functioning between access controllers, which is essential to diagnosing dropped or delayed handoffs experienced by wireless clients moving between APs. It builds on the CAPWAP (Control And Provisioning of Wireless Access Points) architecture referenced in its description, layering H3C-specific roaming management atop that standard framework. It is deployed in H3C WLAN AC/Fit-AP wireless network deployments spanning multiple access controllers where seamless client roaming is required. Engineers can download the HH3C-DOT11-ROAM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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.

Supported Devices

H3C wireless LAN access controllers (AC) and Fit APs

Monitoring Examples

An administrator would check hh3cDot11MobGrpTable/hh3cDot11MobGrpEntry for hh3cDot11MobGrpName, hh3cDot11MobGrpSrcIPAddr, and hh3cDot11MobGrpAuthMode to confirm mobility group peering is correctly configured between access controllers. Reviewing hh3cDot11MobGrpMemberTable/hh3cDot11MobGrpMemberEntry and each member's hh3cDot11MobGrpMemberIpAddr verifies all expected AC peers are present in the mobility group. If wireless clients report failed or slow roaming between buildings served by different ACs, hh3cDot11RoamStatisGroup counters would be inspected to see whether inter-AC roaming attempts are failing at a higher-than-normal rate.

How to Use in IPNetwork Monitor

Example using hh3cDot11IntraACRoamingSuccCnt2 OID:

Select an H3C wireless access controller/Fit AP (inter-AC roaming/mobility groups) 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 hh3cDot11IntraACRoamingSuccCnt2 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
hh3cDot11ROAM	1.3.6.1.4.1.25506.2.75.10			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.
