Stackable PoE+ switches allow easier management at the access layer and improve work efficiency. This section explains stacking and its related concepts, identification methods, and the benefits of managing multiple switches as a single. The Cisco Catalyst 9300 is one of the most widely deployed enterprise access and aggregation switches. Yet IT managers and network engineers often have detailed questions before deploying or upgrading to this model. This guide organizes the most common questions into five categories: performance. Cisco ® Catalyst ® 9000 software and hardware have been designed to address these current and future demands.
