Description
Cisco Catalyst C9300X-12Y Fiber Switch
High-Speed Fiber Aggregation | 12x 1G/10G/25G SFP28 | 1-Tbps Stacking | Data-Only
The Cisco Catalyst C9300X-12Y is a highly scalable, high-throughput enterprise-grade fiber switch engineered for optimal access and distribution layer aggregation. Featuring 12 fixed downlinks that support line-rate 1G, 10G, and 25G SFP28 optics, this platform is ideal for linking downstream switches, core components, and high-performance server configurations. Built on the powerful UADP 2.0sec ASIC, it incorporates hardware-accelerated 100G IPsec encryption and robust x86 application hosting to safeguard high-density campus and branch topologies.
Licensing & Add-On Options
This hardware maintains its native, permanent, and non-expiring base license tier (Network Essentials or Network Advantage) directly on the iron. To align with your centralized deployment strategy, choose from these compatible add-on license structures:
- Cisco Catalyst / DNA Subscription Add-ons (3, 5, or 7-Year Terms): Available in Essentials or Advantage variants. Mandatory if orchestration is driven by Cisco Catalyst Center. Upgrading to an active Advantage term automatically triggers full Network Advantage routing layers natively across your local hardware platform.
- Cisco Meraki Cloud Dashboard Integration: This hardware profile can be ordered or converted to support seamless Meraki cloud-managed infrastructure tracking, granting network administrators centralized dashboard monitoring.
- ThousandEyes Network Synthetics: Bundled natively as an entitlement when choosing a Cisco DNA Advantage subscription, unlocking continuous path visualization from your distribution edge directly to hybrid multi-cloud systems.
- HSECK9 High-Security Crypto Engine: Required as a regulatory add-on license only if your topology demands the activation of full line-rate 100 Gbps AES-256 IPsec hardware tunnel traffic.
Key Technical Features
⚡ High-Density 25G Fiber
Equipped with 12 fixed SFP28 ports that dynamically auto-negotiate 1G, 10G, or 25G fiber links to match varying link speeds.
? Cisco StackWise-1T Ready
Supports up to 1 Tbps of resilient backpanel stacking bandwidth. Mix and stack seamlessly with other Catalyst 9300X configurations.
? 100G Hardware IPsec
Localized crypto acceleration embedded within the ASIC layout drives ultra-secure site-to-site tunnels without compromising port speeds.
?️ Modular Expansion Bay
Features one empty slot accepting optional C9300X uplink modules, allowing expansion into massive 40G or 100G backbone uplinks.
?️ Edge Containers & App Hosting
An x86 architecture with 16GB RAM supports native scripting or hosting third-party security apps like inline virtual firewalls.
? Smart Power Resiliency
Shares the same physical dual hot-swappable fans, power cables, and StackPower logic as the rest of the 9300 enterprise family.
