As a result, it efficiently powers devices like IP phones, wireless access points, and IoT devices, simplifying cabling and reducing costs. For example, it supports high-density Wi-Fi 6 and 802.11ac Wave2 deployments, ensuring seamless connectivity for modern applications.

2. Flexible Uplink Options: Next, the inclusion of 4 dedicated 1G SFP uplink ports enables high-speed backbone connections. Consequently, these ports support both twisted pair (1000Base-T) and optical fiber (1000Base-X), offering flexibility for network expansion. In addition, the modular design allows easy integration with existing infrastructure.

3. Layer 3 Switching Capabilities: Furthermore, the switch operates as a Layer 3 device, supporting advanced routing protocols. This capability, therefore, enhances network scalability and segmentation, making it ideal for complex enterprise environments. For instance, it enables efficient traffic management through features like Access Control Lists (ACLs) and Quality of Service (QoS).

4. Cisco StackWise-320 Technology: Moreover, the switch supports Cisco StackWise-320, providing up to 320 Gbps of stacking bandwidth. As a result, it allows seamless stacking with other Catalyst 9300L models, ensuring high availability and resiliency. Specifically, it supports nonstop forwarding with Stateful Switchover (NSF/SSO), minimizing downtime to sub-50 milliseconds.

5. Software-Defined Access (SD-Access): Additionally, the switch integrates with Cisco’s SD-Access architecture, powered by Cisco IOS XE. Consequently, it enables policy-based automation, network virtualization, and group-based policies. For example, administrators can segment traffic using security groups like “IoT device” or “Guest,” enhancing security and simplifying management.

6. Advanced Security Features: In addition, the switch leverages Cisco’s Unified Access Data Plane (UADP) 2.0 ASIC, offering programmable pipeline and micro-engine capabilities. As a result, it supports robust security features like encrypted traffic analytics and TrustSec for scalable security policies. Therefore, it protects against advanced persistent threats.

7. Meraki Cloud-Management Option: Furthermore, the switch can migrate to a Meraki-managed persona, integrating with the Meraki dashboard for simplified management. Consequently, this feature enhances operational efficiency for organizations seeking cloud-based solutions.

8. Environmental Responsibility: Finally, the switch is RoHS-5 compliant, adhering to strict environmental standards. Thus, it minimizes the use of hazardous substances, making it an eco-friendly choice for sustainable enterprises.
