ADVANCED FEATURES:

StackWise-480 Technology and High Availability:

The WS-C3850-48F-S supports Cisco StackWise-480, allowing up to 9 switches to operate as a single logical unit. This provides centralized management, simplified configuration, and unified monitoring across the stack. StackPower technology allows dynamic power sharing among stack members, ensuring uninterrupted operation in case of a PSU failure. Redundant, hot-swappable fans and power supplies enhance system resiliency, while Virtual Switching System (VSS) capabilities provide seamless failover. These features ensure minimal downtime and continuous connectivity for mission-critical enterprise and campus networks. It also simplifies maintenance by consolidating multiple devices into one manageable logical entity.

Zero-Touch Provisioning (ZTP) and Full Automation:

Zero-Touch Provisioning enables automated deployment of the switch without manual configuration, accelerating rollouts for large-scale network deployments. Full programmability is supported through NETCONF/YANG, RESTCONF, Python scripting, and integration with Cisco DNA Center or third-party automation platforms. Event-driven automation, policy-based workflows, and automated rollback mechanisms streamline network operations, reduce human error, and ensure consistent configuration across all devices. Additionally, pre-defined templates and scripts allow fast deployment of multi-site networks, reducing operational complexity and provisioning time. This also supports hybrid network architectures with centralized orchestration and monitoring.

Flexible NetFlow (FNF), Advanced Telemetry, and Predictive Analytics:

Flexible NetFlow provides detailed per-flow traffic monitoring, offering deep insights for capacity planning, application behavior analysis, and anomaly detection. Embedded Event Manager (EEM) enables automated responses to network events, such as link failures or configuration changes. Streaming telemetry and real-time data collection integrate with AI-driven analytics platforms for predictive maintenance, proactive network optimization, and automated root-cause analysis. This enables administrators to anticipate potential issues before they impact users. Historical traffic trend analysis also supports SLA enforcement and network policy refinement.

MACsec Encryption and Enterprise-Grade Security:

MACsec (802.1AE) encryption ensures secure end-to-end Layer 2 communications, protecting sensitive data from interception or tampering. The switch implements IEEE 802.1X authentication, DHCP snooping, IP Source Guard, and Dynamic ARP Inspection for robust security enforcement. Ingress and egress ACLs, RBAC, and secure management protocols like SSH, RADIUS, TACACS+, and SNMPv3 safeguard against unauthorized access, ensuring compliance in regulated environments. It also supports automated threat detection and logging for audit and compliance reporting. Enhanced security features prevent lateral movement of threats within campus networks.

Advanced Quality of Service (QoS) and Traffic Management:

Eight queues per port, traffic shaping, congestion avoidance, and priority-based queuing guarantee consistent performance for latency-sensitive applications such as voice, video, and critical enterprise workloads. QoS policies can be dynamically applied using automated policy frameworks or Cisco DNA Center, ensuring predictable performance under peak load conditions. Additional features include hierarchical QoS for granular traffic control and classification based on applications or VLANs. This allows enterprises to enforce service-level policies efficiently and optimize network resource usage.

In-Service Software Upgrade (ISSU) and Continuous Operation:

ISSU allows software upgrades and feature additions without network downtime, enabling continuous operation for mission-critical environments. Combined with StackWise redundancy, hot-swappable PSUs, and fans, this ensures uninterrupted network availability and operational continuity. It supports coordinated upgrades across stacked switches and maintains active sessions during the upgrade process. ISSU also reduces administrative workload and risk by allowing incremental software deployment in large-scale networks.

Cloud-Ready Integration and AI-Driven Insights:

Integrates with Cisco DNA Center and Cisco Prime Infrastructure for centralized management, AI-driven monitoring, predictive analytics, and automated policy enforcement. Supports telemetry collection, application-aware traffic monitoring, and segmentation policies across distributed campus and enterprise networks. AI-driven insights reduce troubleshooting time, optimize resource allocation, and enable intelligent decision-making for network planning and capacity management. Administrators can also leverage historical and real-time analytics to forecast network growth and optimize performance. Cloud-ready integration simplifies multi-site management with centralized dashboards and alerts.

Energy Efficiency and Sustainable Operations:

Supports Energy Efficient Ethernet (EEE) and intelligent power management to minimize energy consumption during low-traffic periods. Hot-swappable, field-replaceable fans and dual AC or optional 1100W PSUs provide flexible deployment and cooling efficiency. The 1U form factor allows high-density deployment while maintaining minimal power and cooling footprint. Energy monitoring and dynamic adjustment of interface power consumption reduce operational costs. These features support environmentally responsible networking and contribute to green data center initiatives.

Flexible Uplink and Expansion Options:

Modular uplink slots support 1G and 10G SFP modules, with optional 25G/40G/100G interfaces for future scalability. This ensures seamless integration into high-performance enterprise, campus, or hybrid cloud networks. Administrators can mix and match uplink speeds to optimize bandwidth allocation. Expansion slots allow incremental upgrades without requiring full device replacement, ensuring long-term investment protection.

Comprehensive Monitoring, Analytics, and Reporting:

Supports real-time telemetry, flow-based monitoring, and detailed analytics for capacity planning, SLA assurance, and proactive troubleshooting. Administrators can monitor bandwidth utilization, application performance, and traffic patterns across the network. Integration with Cisco DNA Center or third-party analytics tools enables predictive maintenance, anomaly detection, and long-term trend analysis. This ensures operational efficiency, end-to-end visibility, and reliable service delivery. Historical reporting and automated alerting help maintain compliance and optimize network performance.

Multi-Tenant and Layer 2/3 Overlay Support:

Supports advanced multi-tenant environments using Layer 2/3 overlays, EVPN-VXLAN, and virtualized network segmentation. Simplifies workload mobility across campuses or data centers, allowing policy enforcement without physical reconfiguration. It is ideal for organizations adopting hybrid cloud architectures or requiring secure multi-tenant isolation for different departments or clients. These capabilities enhance network flexibility and provide a future-proof platform for digital transformation initiatives. Network segmentation and isolation also improve security and compliance for enterprise applications.
