Cisco Software-Defined Access

Vemula, Srilatha, Gooley, Jason, Hasan, Roddie



Direct from Cisco, this comprehensive book guides networking professionals through all aspects of planning, implementing, and operating Cisco Software Defined Access, helping them use intent-based networking, SD-Access, Cisco ISE, and Cisco DNA Center to harden campus network security and simplify its management.
Drawing on their unsurpassed experience architecting SD-Access solutions and training technical professionals inside and outside Cisco, the authors cover all facets of the product: its relevance, value, and use cases; its components and inner workings; planning and deployment; and day-to-day administration, support, and troubleshooting. Case studies demonstrate the use of Cisco SD-Access components to address Secure Segmentation, Plug and Play, Software Image Management (SWIM), Host Mobility, and more. Building on core concepts and techniques, the authors present full chapters on advanced SD-Access and Cisco DNA Center topics, as well as detailed coverage of fabric assurance.
