C9300-24UXB-A Description

Cisco Catalyst 9300-24UXB-A is the flagship higher-scale multigigabit model with the Network Advantage feature set. Twenty-four 10 G/5 G/2.5 G/1 G/100 M RJ-45 ports deliver 60 W UPOE for Wi-Fi 6E APs, IoT sensors and LED lighting.A 64 MB deep packet buffer maintains zero-loss performance for 4K/8K media and micro-burst trading traffic while the non-blocking 640 Gbps switching fabric and 480 Gbps StackWise-480 links scale to 1.12 Tbps in an eight-member stack.With Network Advantage, the switch unlocks SD-Access segmentation, L3 routing, ETA encrypted-traffic analytics and API programmability—ideal for secure campus fabrics and edge compute workloads.

Key Features

Network Advantage Feature Set

Ships with the full –A license, unlocking Layer 3 routing, SD-Access fabric segmentation, Encrypted-Traffic Analytics, and open APIs for automation.

64 MB Deep-Buffer Architecture

Four-times the standard buffer (16 MB) for true zero-drop performance during 4K/8K video bursts, high-frequency trading spikes, or large data backups.

24 × 10 Gb Multigig UPOE Ports

Each copper port negotiates 100 M/1/2.5/5/10 Gbps and delivers up to 60 W UPOE—perfect for Wi-Fi 6E APs, LED lighting, security cameras, and XR endpoints.

640 Gbps Switching + 480 Gbps StackWise-480

Non-blocking fabric per chassis and sub-50 ms fail-over across up to eight higher-scale members, yielding 1.12 Tbps aggregate bandwidth.

Hot-Swap Modular Uplink Bay

Accepts 4×1 G, 8×10 G, 4×10 G-mGig, 2×25 G SFP28, or 2×40 G QSFP+ modules—future-proofing your backbone without forklift upgrades.

Enterprise-Grade Security & Resiliency

Secure Boot, Trust Anchor SUDI, AES-256 MACsec, redundant FRU fans/PSUs, and StackPower pooling for shared power across switches keep the network both protected and always on.

Applications Scenarios

High-Frequency Trading Pods

64 MB buffer + 10 Gb UPOE ports absorb micro-burst market data; StackWise-480 adds < 50 ms fail-over so orders never drop.

SD-Access Smart Hospital

Network Advantage enables micro-segmentation for patient, guest, and IoT VLANs, while 60 W UPOE powers 4K imaging panels and bedside sensors over single cables.

Wi-Fi 6E Stadium Bowl

24 multigig ports drive high-draw APs and UHD cameras; deep buffer smooths halftime upload spikes, and 40 Gb uplinks stream 8 K video to the control room lag-free.
