Description
Cisco Catalyst C9300-24UXB Switch
High-Scale & Deep Buffer Multigigabit | 24-Port 10G mGig | 60W Cisco UPOE | 32MB Buffer
The Cisco Catalyst C9300-24UXB is the ultimate ultra-premium stackable enterprise access platform, bridging high-density data, immense power delivery, and massive table scales. Built upon the enhanced UADP 2.0 XL ASIC, this deep-buffer model doubles the packet buffer to 32 MB, vastly expanding MAC tables, ACL policies, and Layer 3 routing limits to guarantee lossless transport during critical traffic bursts. Featuring 24 line-rate Multigigabit copper downlinks up to full 10G and utilizing **Cisco Universal PoE (UPOE)** to distribute up to 60W per port, it easily supports high-performance Wi-Fi 6E/7 networks, dense VDI hubs, and intense storage aggregations.
Key Technical Features
* 32MB Deep Packet Buffer
Powered by the UADP 2.0 XL ASIC to supply twice the buffer size of standard 9300 units, keeping video, voice, and data streams fluid under heavy network strain.
* Full Line-Rate 10G mGig
All 24 ports feature multi-rate versatility, auto-negotiating speeds across 100M, 1G, 2.5G, 5G, and 10G to maximize high-performance client backplanes.
* 60W Cisco UPOE Capacity
Delivers up to 60W of power per port—double standard PoE+ caps—backed by a large starting default power budget to support advanced workspace devices.
* Stacking Constraints Warning
Supports up to 480 Gbps of stacking bandwidth. Note: Higher-scale "B" switches stack exclusively with other deep-buffer models (e.g., C9300-48UB, 24UB).
* Modular Uplink Versatility
Features a modular network module bay accommodating optional 1G, 10G, 25G, or 40G uplinks to easily adapt as core demands grow.
* Advanced Perimeter Security
Utilizes Encrypted Traffic Analytics (ETA), AES-256 MACsec encryption, and TrustSec architectures to defend high-volume localized data flows.
