Description
C9300X-12Y-A
The Cisco Catalyst C9300X-12Y-A is a high‑performance Layer 2/3 stackable network switch designed for enterprise campus, branch, and data center environments that require high‑speed fiber connectivity and advanced routing features.
It comes with 12 × 25 G/10 G/1 G SFP28 ports for flexible fiber uplinks and access, and supports modular uplink modules (e.g., 10 G/25 G/40 G/100 G options) for scalable network design.
This model runs the Network Advantage software image, delivering advanced Layer 3 routing, security, segment routing, automation, and SD‑Access support — all powered by Cisco IOS XE and StackWise‑1T stacking technology for simplified management and high availability.
Key Features
- Flexible fiber connectivity: 12 SFP28 ports auto‑negotiate 1 G/10 G/25 G for future‑proof networks.
- Modular uplink options: Add uplink modules (10/25/40/100 G) to fit aggregation or core needs.
- Advanced features: Network Advantage offers rich Layer 3 routing (BGP, OSPF, EIGRP), SD‑Access, segment routing, and automation.
- High stackability: StackWise‑1T enables up to eight switches with 1 Tbps stacking bandwidth.
- Security & performance: Hardware support for MACsec and programmable ASIC enhances security and traffic efficiency.
- Cisco IOS XE: Modern OS with programmability, API support, and integration with Cisco DNA Center.
