As network fabric deployments continue to grow larger and more immense, there are challenges involving the management cabling arrangements and debugging mis-cabling issues for large-scale full mesh leaf-spine networks. Additionally, the need for the automatic discovery of every component of a large fabric, which can be expanded dynamically, becomes a challenging task. Accordingly, techniques are presented herein that aid in the automatic detection of mis-cabling issues, the automatic discovery of a rack’s location within a large-scale data center, and the automatic detection of the addition of a new rack to a data center, all without disrupting network traffic within a dynamically expanding fabric. Aspects of the presented techniques provide an algorithm that can automatically detect such mis-cabling issues. Further aspects of the presented techniques support a tool that may be used to detect mis-cabling (e.g., in the case of inter-communication failures among the nodes).
