C9300-24UXB-E Description

Cisco Catalyst 9300-24UXB-E is the deep-buffer, higher-scale member of the Catalyst 9300 family. Its 64 MB packet buffer, 112 Gbps/port fabric, and 256 k flexible-NetFlow entries are purpose-built for loss-less multimedia, financial, and high-frequency IoT traffic. Twenty-four multigigabit copper ports deliver up to 10 Gbps plus 60 W UPOE, while a modular network-module bay accepts 1G, 10G, 25G or 40 G uplink options, safeguarding backbone investments. Secure Boot, AES-256 MACsec, and Trust Anchor ensure tamper-proof operations, and StackWise-480 software lets you manage up to eight higher-scale switches as one.

Key Features

64 MB Deep Packet Buffer

The higher-scale “B” variant quadruples buffer depth to 64 MB, eliminating drops during 4K video bursts, micro-burst trading traffic, and large routing-table updates.

640 Gbps Switching / 476 Mpps Forwarding

Wire-speed Layer 2/3 throughput per chassis, expandable to 1.12 Tbps and 833 Mpps in an eight-switch StackWise-480 fabric.

Up to 256 K Flexible NetFlow Entries

Multigigabit models support 256,000 flow records for granular traffic analytics and security baselining without external probes.

24× Multigigabit UPOE Ports (60 W)

Each copper downlink auto-negotiates 100 M/1G/2.5G/5G/10G while delivering Cisco UPOE power, ideal for Wi-Fi 6E APs, IoT sensors and LED lighting.

Hot-Swap Modular Uplink Bay

Choose 4×1 G, 8×10 G, 2×25 G or 2×40 G network modules as backbone needs evolve, preserving chassis investment.

StackWise-480 Resiliency & Scale

Hardware-based 480 Gbps stack links provide sub-50 ms fail-over and single-IP management across up to eight higher-scale switches, delivering 1120 Gbps aggregate fabric.

Applications Scenarios

High-Frequency Trading

64 MB buffer absorbs micro-bursts, 10 Gb UPOE powers desk devices, and StackWise-480 gives < 50 ms fail-over for zero-loss trades.

Medical Imaging Lab

10 Gb multigig to GPU servers, 2 × 25 Gb uplinks for spine, MACsec protects patient data, UPOE drives 4 K displays.

Smart Stadium Edge

60 W UPOE feeds Wi-Fi 6E APs, UHD cameras, LED lights; deep buffer soaks halftime uploads; 40 Gb uplinks stream flawless 8 K video.
