Cisco Catalyst 9000 Series Switches Details
Cisco Software-Defined Access and Cisco StackWise Virtual are offered through Cloud Network Solutions as part of the solutions based Cisco Catalyst 9000 Series Switches.
Cisco SD-Access is the next-generation architecture for the enterprise network and is a key feature of the Cisco Catalyst 9000 Series Switches. Aligned with the included Cisco DNA, it uses a centralized controller to provide a management framework. This framework will simplify the provisioning of your network, administer group-based policy for users, and provide telemetry to help identify problems and provide corrective actions.
Cisco SD-Access also transforms the network from a vendor proprietary system to an open and programmable infrastructure. Rather than dealing with disparate networks and setting up multiple VLANs, it automates many processes and supports virtualization. Thanks to its long-term cost reduction, centralized management, on‑demand provisioning, and network flexibility, Cisco SD-Access provides operational and strategic advantages over traditional enterprise networks.
Cisco StackWise Virtual is an advanced stacking technology that supports both access and distribution deployments through multiple topologies. It provides higher scale for system virtualization at the network layer. A StackWise Virtual configuration in the distribution layer of the network interacts with the access and core layer switches as if it were a single logical switch. An access/core switch connects to both switches of the StackWise Virtual placement using one logical port channel known as Multi-Chassis EtherChannel (MEC). StackWise Virtual also simplifies the Layer 3 network topology by reducing the number of routing peers in the network and depicting itself as one logical switch.
