Abstract: Examples disclosed herein relate to a method comprising receiving a control packet originating from a originating network device. The control packet may have a control MAC address identifying the originating network device and the control packet is used for determining a traffic loop in a network including the first network device and the originating network device. The method may include determining, by the first network device, whether the control MAC address of the control packet matches a MAC address of the first network device. Wit is determined that the control MAC address of the control packet matches a MAC address of the first network device, the method may include determining that the match is indicative of the loop and blocking a port of the first network device that the control packet arrived on without blocking any other ports on the first network device.

Abstract: Aspects of workflow-driven hardware component management are disclosed. A workflow is generated for a job to be performed for management of a hardware component. The workflow includes a 3-Dimensional (3D) model of the hardware component. A job identifier may be allocated to a resource person associated with a resource device to provide job-based access rights for performance of the job. Directions are provided to the resource device based on the workflow to indicate actions to be taken for performing the job. The directions may include Augmented Reality images based on the 3D model. The job-based access rights are revoked on completion of the job.
