The Cisco Catalyst 9300X-12Y-E is a high-performance, stackable Layer 3 switch purpose-built for enterprise campus aggregation, data center edge, and high-speed fiber deployments. It delivers 12 x multi-rate SFP28 ports (25G/10G/1G) and a modular uplink bay, powered by the Cisco DNA Network Essentials license for robust automation, security, and Layer 3 functionality.
12 x SFP28 Ports: Multi-rate support for 25G, 10G, and 1G fiber connections, enabling seamless migration from 10G to 25G.
Modular Uplink Module: 1 x hot-swappable bay supporting high-speed modules:
2x100G/40G (C9300X-NM-2C)
4x100G/40G (C9300X-NM-4C)
8x25G/10G (C9300X-NM-8Y)
Non-PoE: Optimized for pure data switching in high-bandwidth, fiber-rich environments.
StackWise-1T: Industry-leading 1 Tbps stacking bandwidth; stack up to 8 switches for unified management.
StackPower: Power supply sharing across the stack for N+1 redundancy.
Non-Stop Forwarding (NSF/SSO): Sub-50ms failover for zero downtime during stack transitions.
UADP 2.0sec ASIC: Wire-speed Layer 2/3 switching with hardware-accelerated security.
Security: MACsec-256 encryption, Secure Boot, and ACLs for data protection.
Switching Capacity: 1 Tbps (single unit) / 2 Tbps (stacked).
Forwarding Rate: 744.04 Mpps (single unit) / 1488 Mpps (stacked).
Cisco IOS XE: Programmable OS with NETCONF/YANG for model-driven automation.
Cisco DNA Essentials: Network automation, telemetry, and monitoring via Cisco DNA Center.
Flexible NetFlow (FNF): Deep traffic visibility for monitoring and threat detection.
Layer 3 Routing: Static routing, RIP, EIGRP, OSPF, VRF-Lite.
