Cisco C9300X-12Y-E Catalyst 9300X 12-Port 25G SFP28 1Tbps StackWise-1T Managed Switch

The Cisco C9300X-12Y-E is a managed switch from the Catalyst 9300X Series, built for high density campus core and distribution deployments needing native 25 Gigabit Ethernet. The "E" designates Network Essentials licensing, the same hardware as the C9300X-12Y-A but without Network Advantage features like BGP, EIGRP, IS-IS, VXLAN, and VRF, making it the right fit for simpler Layer 2 and basic routed access deployments that don't need full dynamic routing or segmentation. It provides 12 fixed ports supporting 25, 10, or 1 Gigabit Ethernet over SFP28 optics, alongside a modular uplink slot for adding 10G, 25G, 40G, or 100G connectivity as needed. Switching capacity reaches 1,000 Gbps standalone, doubling to 2,000 Gbps when stacked with StackWise-1T, the industry's highest back panel stacking bandwidth solution. Forwarding rate reaches 744.04 Mpps standalone and 1,488 Mpps when stacked across up to 8 members. Network Essentials still includes routed access basics like static routing, RIP, EIGRP stub, and OSPF with up to 1,000 routes, along with 802.1X and MACsec-128 security. This is a fiber only switch with no PoE support, reflecting its role as a high speed aggregation and core platform rather than an access layer switch. The x86 CPU architecture, 16GB of DRAM, and 16GB of flash storage support container based application hosting directly on the switch.
