Core Hardware and Architecture
The Cisco Catalyst C9300LM-48T-4Y-1A is a 48-port modular switch built for flexible enterprise edge deployments. Key specifications include:
- 48x 1GBase-T RJ45 ports and 4x 1G/10G SFP+ uplinks, supporting 10GBase-T via Cisco Multigigabit technology.
- Modular network module slot for adding 40G QSFP+, 25G SFP28, or 10G interfaces post-deployment.
- StackWise-320 support, enabling 320 Gbps stacking bandwidth and unified management of up to 8 switches.
- Cisco DNA Advantage license (included) for SD-Access, AI-driven insights, and encrypted traffic analytics.
Addressing Critical Deployment Questions
Q: What distinguishes the “LM” variant from standard C9300L models?
The C9300LM-48T-4Y-1A includes a field-upgradable network module slot, allowing operators to add high-speed uplinks (e.g., 40G) without replacing the entire chassis—ideal for future-proofing edge sites.
Q: How does DNA Advantage reduce operational complexity?
The license automates policy enforcement across wired/wireless devices, provides predictive failure analysis, and integrates with Cisco Stealthwatch® for network-wide threat visibility.
Performance Benchmarks and Use Cases
- Bandwidth: Delivers 176 Gbps switching capacity with 130 Mpps forwarding rate, suitable for VoIP and real-time surveillance systems.
- Hybrid Workloads: Use the modular slot to add 10GBase-T ports for high-density workstation clusters or 25G uplinks for data center interconnects.
- IoT Aggregation: Segment OT/IT traffic using Cisco TrustSec®, enforcing role-based access for industrial sensors and legacy devices.
Licensing and Cost Efficiency
The DNA Advantage license offers:
- Lifetime access to software-defined segmentation and automated application QoS.
- No recurring fees for core features, reducing 5-year TCO by ~35% vs. subscription-based alternatives like Aruba CX 6300.

Practical Deployment Insights
During a recent logistics hub upgrade, the modular slot allowed adding 40G uplinks to handle 10,000+ IoT sensor data streams—without replacing existing switches. While Juniper’s EX4400 matches its port density, Cisco’s StackWise-320 enabled seamless scaling from 2 to 8 switches during peak shipping seasons. For enterprises prioritizing adaptability over upfront cost, this model’s modularity and DNA Advantage tools redefine edge network agility.
