Switch L3 gerido Cisco Catalyst C9300X-12Y-A 1000 Gbit/s 32000 MAC

The Cisco Catalyst C9300X-12Y-A is a managed L3 switch designed for enterprise deployments that demand security, IoT convergence, mobility and cloud readiness. It provides a switching capacity of 1000 Gbit/s and a MAC address table that supports up to 32,000 entries. Built on the Catalyst 9300 Series platform and the UADP architecture, this switch supports high-density stacking, flexible uplinks and advanced programmability with Cisco IOS XE.

Advantages

The switch offers high switching capacity and a large MAC table suitable for dense network environments, hardware crypto support on Catalyst 9300X models, and broad IEEE standard compatibility. It supports high-density PoE options including PoE+, Cisco UPOE and UPOE+ power capabilities, resilient StackWise and StackPower architectures for stacking and redundant power, and an x86-based CPU with increased memory to run containers and third-party applications natively.

Suitable for

• Enterprise access layer aggregation
• Environments requiring high-density uplinks and stacking
• Deployments integrating Wi‑Fi 6 access points and IoT devices
• Networks needing hardware crypto/IPsec acceleration
• PoE/PoE+/UPOE powered device deployments (phones, cameras, APs)

How to use

Install the switch in a standard 19-inch rack and connect uplinks and access ports according to your network design. Use the Cisco IOS XE command-line interface or management tools (such as Cisco DNA Center or Prime Infrastructure) to configure Layer 3 routing, VLANs, QoS and security policies. For stacking, follow Cisco StackWise procedures to connect stack cables and verify stack member roles. When using PoE, verify power budgets and configure port power settings as required.

Recommendations

Place the Cisco Catalyst C9300X-12Y-A at the access or distribution layer in enterprise networks where high throughput, stacking, and hardware-accelerated security are required; ensure firmware and security patches are kept up to date and plan power budgets for PoE/UPOE deployments.
