Catalyst 9K Overview (C9KO)

This Cisco IT training class covers the Cisco Catalyst 9000 Series switches which are the next generation Cisco Catalyst family of enterprise LAN access, aggregation and core switches. They form the foundational building block for Cisco Digital Network Architecture (Cisco DNA™) and for an entirely new era of networking.

The goal of this Cisco DNA course is to understand the first purpose-built platforms designed to take advantage of the DNA and Cisco Software-Defined Access (SD-Access). The students will comprehend how the Catalyst 9000 Series delivers high performance and functionality, plus exceptional power delivery scale with industry’s highest density of Cisco Universal Power Over Ethernet (Cisco UPOE™) ports. At the end of the course, the student will be able to describe the features and benefits of the Catalyst 9000. View additional Catalyst 9K Overview course details below.
