  • Processing: Cisco UADP 2.0 ASIC delivers 154 Mpps throughput (vs. 118 Mpps on C9300-24UB).

  • Memory: 4GB DDR4 base (expandable to 8GB), handles 10K+ ACL rules concurrently.

  • Storage: Dual-partitioned 16GB eMMC stores 3 IOS-XE images for fail-safe operations.

2. Breakthrough Capabilities

  • DNA Essentials: Enables SD-Access automation (license required).

  • Hardware Encryption: Line-rate MACsec 256-bit for financial/medical compliance.

  • PoE++: 90W per port (740W total) powers APs/cameras/digital signage.

3. Industrial Design Profile

  • Compact chassis (440×300×44mm) operates at -5°C to 50°C.

  • Modular fan trays increase cooling efficiency by 40% in stacked racks.

  • Tool-less air filter ideal for dusty environments.

4. Real-World User Insights

University IT Director's Test:
“AP roaming latency dropped from 120ms to 20ms after replacing 3850s. CLI command show platform hardware throughput doubles troubleshooting speed.”

5. Pricing & TCO Analysis

  • MSRP: $3,500 (incl. 3-yr DNA Essentials)

  • Refurbished: ~$1,800 (lacks software subscriptions)

  • Efficiency: $0.08 per GB (5-year TCO)

6. Power & Thermal Efficiency

  • Typical Draw: 37W (no PoE) / 577W (max)

  • EnergySave Tech: Idle ports consume 0.1W

  • Field Data: Saves $210/year vs. 2960X under full IP phone+AP load

7. Compatibility & Expansion
