Description: H3C MIB for 802.11 wireless client roaming management including inter-AC roaming and handoff statistics.

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-ROAM-MIB?

H3C-DOT11-ROAM-MIB is an H3C MIB for managing IEEE 802.11 wireless client roaming, specifically inter-Access Controller (AC) roaming via mobility groups that let wireless clients hand off seamlessly between access points managed by different ACs. It exposes configuration data for mobility groups, including group name, tunnel type, source IP address, authentication mode/key, and per-group member AC IP addresses, as well as roaming status and statistics groups. This MIB is used to monitor the software/configuration status of the wireless roaming infrastructure, letting an operator confirm a mobility group and its member ACs (h3cDot11MobGrpMemberTable) are correctly enabled (h3cDot11MobGrpEnable) and operational, and to review roaming statistics to detect failed or slow handoffs affecting client experience. It builds on IEEE 802.11 wireless LAN standards and H3C's AC/AP wireless controller architecture rather than a separate IETF MIB. It is typically deployed in enterprise or campus WLAN environments using H3C wireless access controllers managing multiple APs across roaming domains, and administrators can consult the H3C-DOT11-ROAM-MIB MIB definition directly when building custom roaming-health monitoring templates.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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 access controller (AC)
H3C wireless LAN infrastructure

Monitoring Examples

An operator would poll h3cDot11MobGrpTable/h3cDot11MobGrpEntry to verify h3cDot11MobGrpEnable is true and h3cDot11MobGrpRowStatus is active for each configured mobility group, then check h3cDot11MobGrpMemberTable/h3cDot11MobGrpMemberEntry for each member AC's h3cDot11MobGrpMemberIpAddr to confirm all expected ACs are participating in the group. Reviewing the h3cDot11RoamStatisGroup counters alongside h3cDot11RoamStatusGroup would reveal a rising rate of failed roams, indicating a misconfigured h3cDot11MobGrpAuthKey or tunnel issue between ACs.

What Can Be Monitored

mobility group enable/row status
member AC IP addresses in mobility group
tunnel type and authentication mode
roaming status
roaming statistics (handoff counts/failures)

How to Use in IPNetwork Monitor

Example using h3cDot11IntraACRoamingSuccCnt2 OID:

Select an H3C wireless access controller (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 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	1.3.6.1.4.1.2011.10.2.75.10			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.
