Description: Monitors Aruba wireless controller high-availability cluster state, redundancy status, and failover events.

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 WLSX-HA-MIB?

WLSX-HA-MIB is an Aruba Networks (HPE) wireless controller MIB providing information about the controller's High Availability subsystem, which manages redundant controller pairing and automatic failover. It defines trap object and trap definition groups used to notify a network management station of HA-related state changes rather than exposing a large set of polled status tables. Its role in monitoring is centered on system/software availability status: it is used to detect controller failover events, redundancy state transitions, and cluster health changes that directly indicate whether a standby controller has taken over for a failed primary. This MIB depends on the broader Aruba WLSX MIB family and controller HA feature set, and would typically be interpreted alongside general system uptime and interface status objects. It is deployed on paired/clustered Aruba wireless LAN controllers in enterprise environments requiring high-availability wireless management, and WLSX-HA-MIB SNMP monitoring is how operations teams get immediate notice of a failover event as it happens.

IPNetwork Monitor allows you to monitor SNMP objects defined in WLSX-HA-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

Aruba Networks (HPE) wireless LAN controller (HA pair/cluster)

Monitoring Examples

The two sample objects, wlsxHaTrapObjectsGroup and wlsxHaTrapDefinitionGroup, indicate this MIB is oriented around trap definitions for HA events rather than a rich set of pollable runtime tables; an NMS would subscribe to these traps to be alerted the moment an Aruba controller failover occurs. When a primary controller in an HA pair goes down, the standby taking over would generate a notification defined under wlsxHaTrapDefinitionGroup, carrying details captured in wlsxHaTrapObjectsGroup, alerting operations staff to investigate the failed unit. Because there is little polled table data confirmed here, ongoing state polling would typically rely on companion WLSX MIBs for controller status.

How to Use in IPNetwork Monitor

Example using haTotalHbtRequestsSent OID:

Select an Aruba Networks (HPE) wireless LAN controller, HA pair/cluster (failover/redundancy-state trap notification status) 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 haTotalHbtRequestsSent 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 total number of hbt requests sent. 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.
