1. Core Specifications & Performance Benchmark
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.
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.
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.
University IT Director's Test:
“AP roaming latency dropped from 120ms to 20ms after replacing 3850s. CLI commandshow platform hardware throughput
doubles troubleshooting speed.”
MSRP: $3,500 (incl. 3-yr DNA Essentials)
Refurbished: ~$1,800 (lacks software subscriptions)
Efficiency: $0.08 per GB (5-year TCO)
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
