What Is the Cisco C9200L-24P-4G-A++?
The Cisco C9200L-24P-4G-A++ is a Catalyst 9200L Series switch optimized for high-density Power over Ethernet (PoE) environments in enterprise access layers. It features 24x 1G PoE+ ports, 4x 1G SFP uplinks, and 740W total PoE budget, paired with Cisco DNA Advantage Plus licensing for advanced automation, security, and assurance. Designed for campuses and IoT-heavy deployments, it balances scalability and energy efficiency for dynamic workloads.
Key Technical Specifications
- Port Layout: 24x 10/100/1000BASE-T PoE+ ports (30W per port) and 4x 1G SFP uplinks.
- PoE+ Budget: 740W total, supporting full PoE+ utilization across all ports.
- Performance: 176 Gbps switching capacity and 132 Mpps throughput for high-traffic scenarios.
- Licensing: DNA Advantage Plus (pre-bundled), enabling AI-driven network insights, software-defined segmentation, and predictive analytics.
- Resiliency: StackWise-320 for stacking up to 8 switches and hitless ISSU (In-Service Software Upgrade).
- Security: MACsec encryption, Cisco TrustSec, and Secure Network Analytics for real-time threat detection.
C9200L-24P-4G-A++ vs. Base C9200L-24P Models
| Feature | C9200L-24P-4G-A++ | C9200L-24P |
|---|---|---|
| Licensing Tier | DNA Advantage Plus | DNA Essentials or None |
| Automation | Intent-based networking (IBN) | Basic CLI/SNMP management |
| Analytics | Predictive issue resolution | Standard telemetry |
| Security | Encrypted Traffic Analytics (ETA) | Basic ACLs and port security |
Why Deploy the C9200L-24P-4G-A++ in Enterprise Networks?
- High-Density PoE: Powers 48V devices like Wi-Fi 6 APs, PTZ cameras, and digital signage without external power injectors.
- AI-Driven Operations: DNA Center integration automates firmware updates, QoS policies, and anomaly detection, reducing manual tasks by 50%.
- Scalable Architecture: StackWise-320 enables unified management of distributed switches, ideal for multi-building campuses.
For enterprises prioritizing intelligent PoE infrastructure, the C9200L-24P-4G-A++ is available at itmall.sale.
Ideal Use Cases
- University Campuses: Connect smart classrooms, dormitories, and research labs with role-based access control.
- Healthcare Facilities: Secure medical IoT devices and prioritize telemedicine traffic via automated QoS.
- Warehouse Automation: Support autonomous robots, inventory scanners, and HVAC systems with sub-5ms latency.
Addressing Critical User Questions
Q: Can this switch support UPOE (90W) for devices like VR headsets?
No. While it delivers 30W per port, upgrading to Catalyst 9300 switches is required for 90W UPOE support.
Q: Is DNA Advantage Plus licensing subscription-based?
Yes. It requires 3- or 5-year renewal but includes Cisco TAC premium support during the term.
Q: Does StackWise-320 work with non-Cisco devices?
No. It is proprietary to Catalyst 9200/9300/9400 Series switches running compatible IOS XE firmware.
Final Evaluation
The C9200L-24P-4G-A++ is a cornerstone for enterprises building AI-ready, PoE-driven networks. While its DNA Advantage Plus licensing adds upfront costs, the predictive analytics and zero-trust capabilities eliminate reactive firefighting—a tradeoff that pays dividends in uptime and scalability. For teams eyeing smart campus or Industry 4.0 projects, bypassing this model risks anchoring networks to legacy hardware in an era where adaptability defines success.
