Cisco Catalyst 9300X Switch : 10G/25G Multi-Rate , SD-Access & ETA Threat Detection

The Cisco Catalyst 9300X-48HX-E is a next-generation modular switch designed for high-density 10G/25G connectivity, software-defined networking (SD-Access), and AI-driven security (ETA). Part of the Catalyst 9000 series, it caters to enterprise core, data center edge, and IoT deployments requiring scalability, automation, and encrypted threat visibility.

Key Features & Benefits

1. Multi-Rate Flexibility

   • 48x 10G/25G SFP28 ports (supports 1G/10G/25G via SFP+/SFP28).

   • Modular uplinks: Expand with 8x 100G (C9300X-NM-8X) or future 400G modules.

2. Cisco SD-Access & DNA Center

   • Automate network segmentation, policy enforcement, and zero-trust security.

   • AI/ML-powered analytics for proactive issue resolution.

3. ETA (Encrypted Traffic Analytics)

   • Detect malware in encrypted traffic without decryption, using Cisco Talos threat intelligence.

4. High Availability

   • StackWise-480 technology: 480Gbps stacking bandwidth for resilient architectures.

   • Dual redundant power supplies (AC/DC) and hot-swappable fans.
