C9300-24P-A: Why Is This Cisco Switch a Powerhouse for Modern Enterprise Networks? Features, Licensing, and Deployment Insights

Hardware Overview and Key Specifications

The ​​Cisco Catalyst C9300-24P-A​​ is a 24-port, Layer 3 stackable switch optimized for high-power PoE+ deployments. It combines ​​24x 1GBase-T RJ45 ports​​ (supporting up to 30W PoE+ per port) with ​​4x 1G/10G SFP+ uplinks​​, making it ideal for connecting bandwidth-intensive devices like wireless APs, IP cameras, and VoIP systems.

​​Critical hardware features​​:

• ​​740W total PoE+ budget​​: Powers devices like Wi-Fi 6E access points and PTZ cameras without external injectors.
• ​​StackWise-480 technology​​: Enables stacking of up to 8 switches with 480 Gbps backplane bandwidth.
• ​​Cisco DNA Advantage license​​: Unlocks advanced SD-Access, assurance, and AI-driven analytics.

How Does the C9300-24P-A Differ from Competing Models?

Compared to the Catalyst 9200L series, the C9300-24P-A offers ​​higher PoE capacity​​ and ​​full Cisco DNA Advantage licensing​​ for enterprises requiring end-to-end automation.

​​Key differentiators​​:

• ​​Modular uplink flexibility​​: Supports optional 25G/40G modules for future-ready scaling.
• ​​Enhanced security​​: Built-in ​​Cisco TrustSec​​ and ​​Encrypted Traffic Analytics (ETA)​​ for zero-trust segmentation and encrypted threat detection.
• ​​Resilient stacking​​: Sub-second failover during outages, critical for healthcare and financial networks.

Ideal Use Cases for the C9300-24P-A

This switch excels in environments demanding ​​high power, low latency, and automation​​:

1. ​​Enterprise campuses​​: Deployments with dense Wi-Fi 6/6E APs and IoT devices.
2. ​​Retail spaces​​: Supports digital signage, POS systems, and surveillance cameras.
3. ​​Education networks​​: Manages bandwidth for lecture halls, labs, and dormitories.

A hospital in Texas, for example, reduced cabling costs by 30% using the C9300-24P-A’s PoE+ to centralize power for nurse call systems and medical tablets.

Addressing Top User Questions

​​Q: What’s the difference between the ‘A’ and ‘L’ in C9300 models?​​
The ‘A’ denotes ​​DNA Advantage licensing​​, which includes SD-Access and full API programmability. The ‘L’ (Essentials) lacks advanced automation.

​​Q: Can this switch support 25G uplinks?​​
Yes, via the ​​C9300-NM-8Q​​ module, which adds 8x 10G/25G ports for spine-leaf architectures.

​​Q: Is redundancy possible without stacking?​​
Yes, using ​​dual power supplies​​ (optional) and ​​hot-swappable fans​​, but stacking maximizes uptime.

Final Perspective: Balancing Cost and Capability

The C9300-24P-A is a premium investment, but its ​​scalable PoE, DNA-driven automation, and modular design​​ justify the cost for growing enterprises. Smaller businesses may find the 9200L series sufficient, but for organizations planning IoT expansion or AI-driven network analytics, this model eliminates future upgrade headaches.
