It is part of the Cisco 3850 Series, known for its versatility, scalability, and robust feature set, making it ideal for data centers, enterprise networks, and high-bandwidth applications. This model supports Layer 3 routing, stacking with Cisco StackWise-480 technology, and is managed using the Cisco IOS XE software, providing network administrators with powerful tools for configuration and management.

Key Features:

1. 12 10-Gigabit SFP+ Ports:
   • The WS-C3850-12XS-S offers 12 SFP+ ports for 10-Gigabit Ethernet connectivity, ideal for high-bandwidth, high-speed applications. These ports are designed for fiber-optic connections, enabling long-distance communication at speeds that are critical for data centers, cloud services, and enterprise network backbones. The high speed and fiber-optic support make it well-suited for environments that require low-latency, high-throughput connections between network devices, such as servers, storage systems, and core network switches.
2. Layer 3 Routing:
   • The WS-C3850-12XS-S provides Layer 3 routing capabilities, enabling the switch to perform routing between VLANs (Virtual Local Area Networks). This feature eliminates the need for separate routers to handle inter-VLAN traffic, streamlining the network design. The switch supports advanced routing protocols like OSPF, EIGRP, and RIP, making it capable of handling complex routing configurations in large enterprise networks or data centers.
3. Cisco StackWise-480 Technology:
   • The switch supports Cisco StackWise-480, which enables stacking of up to nine switches to operate as a single unit. This provides higher scalability and redundancy, allowing for easier network management and simplified expansion. Stacked switches function as a single logical device, reducing the need for separate management and offering better fault tolerance. The 480 Gbps stacking bandwidth ensures that stacked switches maintain high performance even as the network scales.
4. Cisco IOS XE Software:
   • The WS-C3850-12XS-S operates on Cisco IOS XE, a versatile and robust network operating system that supports advanced features like network automation, QoS (Quality of Service), multicast routing, and IPv6. Cisco IOS XE is also known for its modular architecture, which allows for continuous software upgrades and provides enhanced security features and performance monitoring capabilities. Network administrators can configure, monitor, and manage the switch using CLI (Command Line Interface), SNMP (Simple Network Management Protocol), or integration with Cisco Prime Infrastructure.
5. High Availability and Redundancy:
   • To ensure continuous operation, the WS-C3850-12XS-S offers redundant power supplies (optional) and hot-swappable fans. These features provide higher fault tolerance by allowing the switch to continue functioning even in the event of a power supply failure or fan malfunction. High availability is essential in environments where downtime is not acceptable, such as data centers or mission-critical applications.
6. Advanced Security Features:
   • The switch is equipped with a range of security features to safeguard the network from unauthorized access and cyber threats. These include Access Control Lists (ACLs), Port Security, 802.1X authentication, Dynamic ARP Inspection (DAI), and IP Source Guard. These tools help prevent DoS attacks, unauthorized device access, and other network vulnerabilities, ensuring the security of sensitive data and systems.
7. Quality of Service (QoS):
   • The WS-C3850-12XS-S supports Quality of Service (QoS), allowing network administrators to prioritize critical applications and traffic. With QoS, high-priority traffic such as VoIP calls, video conferencing, or cloud-based services can be allocated higher bandwidth and low latency, ensuring smooth performance even during periods of network congestion.
8. Energy-Efficient Design:
   • The switch is designed with energy efficiency in mind, supporting Cisco EnergyWise technology to help monitor and manage power consumption across the network. This can reduce energy costs and lower the environmental impact of operating large networks, making it an eco-friendly choice for organizations looking to reduce their carbon footprint.
9. Flexible Management Options:
   • The WS-C3850-12XS-S provides flexibility in how it is managed. It supports CLI (Command Line Interface) for advanced configuration, SNMP for network monitoring, and integration with Cisco Prime Infrastructure for centralized management and reporting. These tools allow administrators to manage large and complex networks more efficiently, ensuring optimal performance and uptime.
10. Scalability:
    • The WS-C3850-12XS-S is highly scalable, making it suitable for organizations that expect growth. With the ability to stack up to nine switches, the StackWise-480 technology allows for seamless expansion without disrupting existing operations. This scalability makes the switch ideal for growing networks where future-proofing is necessary.

Ideal Use Cases:

• Data Centers: The WS-C3850-12XS-S is an excellent choice for data center environments that require 10-Gigabit Ethernet connectivity for high-speed data transfer. Its fiber-optic capabilities and high performance make it ideal for interconnecting servers, storage devices, and network infrastructure in high-demand data environments.
• Enterprise Networks: For large enterprise networks, the WS-C3850-12XS-S provides Layer 3 routing, stacking support, and robust security features, making it suitable for campus networks and enterprise backbones. The switch’s 10-Gigabit ports ensure that large amounts of data can be transmitted quickly and reliably across the network.
• High-Bandwidth Applications: If your network handles high-bandwidth applications such as cloud computing, virtualization, or video streaming, the WS-C3850-12XS-S is equipped to handle large volumes of traffic efficiently. Its QoS and 10-Gigabit capabilities ensure that critical applications get the resources they need for optimal performance.
• Medium to Large-Sized Businesses: Medium and large businesses looking to build or expand their network infrastructure will benefit from the scalability and high performance of the WS-C3850-12XS-S. It supports fiber-optic connectivity and stacking, which is crucial for growing organizations with increasing network demands.
