What Is WLSX-TUNNELEDNODE-MIB?

WLSX-TUNNELEDNODE-MIB is Aruba Networks' vendor-specific module for the Controller Transport Service (CTS) "tunneled node" feature, which lets wired clients connected to an access switch have their traffic tunneled back to an Aruba wireless controller for centralized policy enforcement. It exposes configuration and status data about tunneled-node sessions — which wired ports/clients are tunneled, their session state, and associated policy enforcement — bridging wired client management into the wireless controller's policy framework. Its monitoring value lies in confirming the software/service status of this tunnel integration: whether tunneled sessions are up, correctly associated with a controller, and enforcing the intended policy, so a broken tunnel can be caught before it silently drops wired-client connectivity or policy enforcement. It depends on Aruba's broader Controller Transport Service architecture and complements other Aruba WLSX MIBs rather than IETF standard MIBs. It is typically deployed in enterprise networks using Aruba's wired-to-wireless unified policy model, where access switches tunnel wired client traffic to a central controller. Engineers can download the WLSX-TUNNELEDNODE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WLSX-TUNNELEDNODE-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 wireless mobility controller (with tunneled wired access switch ports)

Monitoring Examples

An administrator would poll the tunneled-node session status objects to confirm a given wired switch port's traffic is actively tunneled to the controller and that the session state is up, alerting if a tunnel unexpectedly drops. Per-client/session objects would be checked to confirm the correct policy/role is being enforced on tunneled wired clients, matching what's applied to wireless clients under the same controller. A tunnel session stuck in a down or negotiating state would indicate a wired client has lost centralized policy enforcement and needs investigation. No specific object names were available in the source data for this module, so the above is inferred from its stated purpose of managing the Controller Transport Service.

What Can Be Monitored

  • tunneled-node session state
  • tunneled port/client identification
  • policy/role enforcement status on tunneled clients

How to Use in IPNetwork Monitor

Example using wlsxNumTunnels OID:

Select an Aruba Networks wireless mobility controller 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 wlsxNumTunnels 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. It reports the number of tunnels originating from Tunneled Node. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
