Cisco Catalyst 9300 Series Switches are Cisco’s lead stackable enterprise access switching platform and, as part of the Catalyst 9000 family, are built to transform your network to handle a hybrid world where the workplace is anywhere, endpoints could be anything, and applications are hosted all over the place.
The Catalyst 9300 Series, including the Catalyst 9300X models, continues to shape the future with continued innovation that helps you reimagine connections, reinforce security and redefine the experience for your hybrid workforce, big or small. With Catalyst 9300 Series switches, you choose how you want to manage your network – on-premises, virtual, or from the cloud.
Engineered to support high-performance wireless networks, including Wi-Fi 6 and 802.11ac Wave 2, these switches are designed to scale with growing network demands. Their x86-based CPU and expanded memory capacity enable native hosting of containers, third-party applications, and custom scripts directly on the switch.
