Overview of the C9300X-12Y-10E

The ​​Cisco Catalyst 9300X-12Y-10E​​ is a ​​high-performance Layer 3 switch​​ engineered for enterprise core and aggregation layers demanding ​​ultra-low latency​​, ​​high-density 25G/10G connectivity​​, and scalable architecture. Designed to support bandwidth-intensive applications like AI/ML, real-time analytics, and hyperscale cloud access, this model combines ​​fixed 25G ports​​, ​​modular uplinks​​, and Cisco’s StackWise-1T technology for seamless scalability.


Key Technical Specifications

  • ​Port Configuration​​: 12 x 25G SFP28 ports (10G/25G capable), 4 x 40G/100G QSFP28 uplink slots.
  • ​Stacking​​: ​​StackWise-1T​​ for up to 8 switches in a stack, delivering ​​1.2 Tbps per stack member​​.
  • ​Performance​​: ​​Non-blocking throughput​​ even with advanced features like ACLs and QoS enabled.
  • ​Security​​: ​​MACsec-256 encryption​​, Cisco TrustSec, and Secure Boot for tamper-resistant operation.
  • ​Modularity​​: Optional ​​Network Modules​​ for future 400G uplink upgrades.

Addressing Core User Concerns

​Q: How does this switch handle AI/ML or real-time data workloads?​
The ​​25G port density​​ ensures rapid data transfer between servers and storage clusters, while ​​40G/100G uplinks​​ minimize latency for distributed AI training or real-time database queries.

​Q: Is StackWise-1T suitable for large enterprise cores?​
Yes. With ​​1.2 Tbps per member​​, StackWise-1T scales linearly, allowing enterprises to build resilient, high-bandwidth backbones without redesigning the network.

​Q: Can it secure sensitive data in transit?​
​MACsec-256​​ encrypts data at the hardware level between switches, while ​​Cisco’s Encrypted Traffic Analytics (ETA)​​ identifies threats in encrypted flows without decryption.


Optimal Deployment Scenarios

  • ​Enterprise Core Networks​​: Aggregates traffic from access switches with 25G/40G links.
  • ​AI/ML Clusters​​: Connects GPU/TPU nodes for low-latency model training and inference.
  • ​Hybrid Cloud Gateways​​: Links on-premises infrastructure to public clouds via high-speed uplinks.
