Managed Switch Cisco Catalyst 9300X

The Cisco Catalyst 9300X is a managed Layer 3 switch designed for enterprise networks, offering high-density stacking bandwidth, robust security, and support for IoT, mobility and cloud deployments. It supports full-duplex operation, a MAC address table of 32,000 entries and a switching capacity of 2000 Gbit/s. Built on the UADP architecture and running Cisco IOS XE, the Catalyst 9300X provides flexible uplink options, hardware crypto support, and the ability to host containers and third-party applications for advanced programmability.

Advantages

The switch provides up to 1 Tb stacking bandwidth and a resilient StackWise and StackPower architecture for high availability and flexible PoE delivery including PoE+, Cisco UPOE and UPOE+ up to 90W. Catalyst 9300X models include the UADP 2.5sec ASIC with hardware crypto (including IPsec) and increased CPU and memory resources for native application hosting. Cisco IOS XE adds programmability, advanced security features and support for Software-Defined Access.

Suitable for

• Enterprise campus access and distribution layers
• High-density Wi‑Fi 6 and 802.11ac Wave2 deployments
• Environments requiring resilient stacking and nonstop forwarding (NSF/SSO)
• Networks needing high-capacity uplinks and extensive PoE for powered devices

How to use

Install the switch in a standard 19-inch rack and connect power and uplink interfaces according to the deployment plan. Configure basic network settings (VLANs, SVI, routing protocols) through the CLI or management GUI, enable StackWise and StackPower if deploying multiple units, and apply security policies available in Cisco IOS XE. Use the available 10G/1G ports for access and uplink connections and configure PoE settings per powered device requirements. For advanced use, deploy containers or third-party applications on the switch where supported and manage programmability features through IOS XE APIs.

Usage recommendations

Place Catalyst 9300X switches at access or distribution layers in enterprise networks, ensure firmware and IOS XE are up to date, plan stacking and power budgets before deployment, and follow Cisco best practices for security and high‑availability configurations.
