In one embodiment, a method comprises: establishing a wireless DetNet track for an identified DetNet flow of DetNet packets, and the DetNet track comprising DetNet devices connected by allocated DetNet segments distinct from IP-based connections; causing, by the network device, a DetNet device(s) to execute distributed validating of any one or more DetNet operations by a DetNet forwarding hardware circuit in a DetNet device under test among the DetNet devices, the distributed validating including: generating a DetNet OAM (d-OAM) probe message comprising an ACH header specifying a DetNet validation identifier and a selected bitstring; validating the DetNet forwarding hardware circuit based on outputting the d-OAM probe message, the d-OAM probe message causing a CPU in the DetNet device(s) to selectively generate an IP-based probe response indicating whether a DetNet operation(s) was executed by the DetNet forwarding hardware circuit, independent of an execution speed of any DetNet forwarding hardware circuit.
