Systematising troubleshooting of disputes in network

With the growing network size, virtualization everywhere, it is getting more difficult to configure and manage devices. Software Defined Networking (SDN) a way address these problems. Application Centric Infrastructure (ACI) Cisco’s solution SDN, with centralized automation policy-driven application profiles. If there any bug in or problem expected functionality of network, ACI cases are opened Technical Assistance Centre (TAC) for troubleshooting issue. Engineers currently troubleshoot manually by using Command Line Interface (CLI) trace different events triggered policy pushes logs generated at stages from servers responsible this, which indeed very tedious, time consuming task prone manual errors. This paper describes automate entire process user-friendly GUI can show information needed extracting relevant every layer. By making use FSM models proposed be extended other areas involve log analysis CLI extract not just limited ACI.
