• Automation and programmability: NETCONF, RESTCONF, Cisco DNA Center integration, SD-Access support

The Enhanced Image (“E”) enables full Layer 3 routing capabilities, making this switch suitable for access layer deployments requiring inter-VLAN routing and advanced traffic engineering.

2.4 Physical and Environmental Specifications

The switch is designed for standard 19-inch rack mounting with a 1RU form factor. It weighs approximately 7.5 kg and measures 44.5 cm (width) x 44.5 cm (depth) x 4.4 cm (height). Operating temperature ranges from 0°C to 45°C, with storage temperature from -40°C to 70°C. The device complies with industry standards for electromagnetic emissions and safety certifications.

3. Features and Benefits

3.1 Enterprise-Grade Security

Security is a cornerstone of the C9200L-48P-4G-E design. The switch incorporates Cisco TrustSec technology, enabling role-based access control and segmentation at the hardware level. Features such as MACsec encryption on uplinks (where supported), Dynamic ARP Inspection, and IP Source Guard protect against common Layer 2 attacks and unauthorized access.

Integration with Cisco Identity Services Engine (ISE) allows for centralized policy enforcement and device profiling, critical for zero-trust network architectures.
