In a modern spine-leaf data center, the WS-C3850-48XS-F-S Catalyst 3850 48-port 10G Fiber Switch IP Base serves as a leaf-level aggregator for virtualization and storage servers. Its 48 10G SFP+ uplinks deliver consistent low-latency connectivity and non-blocking throughput to hyper-converged clusters. Benefit: Accelerates east-west traffic, simplifies scaling to hundreds of virtual machines, and ensures predictable performance under heavy I/O loads.
As the aggregation layer in an enterprise campus, the Catalyst 3850 48XS-F-S with IP Base enables Cisco SD-Access segmentation across multiple buildings via 10G fiber trunks. Integrated routing, policy-based ACLs and StackWise-480 stacking support create seamless identity-driven access zones for users, IoT devices and guest networks. Benefit: Enforces consistent security policies, reduces broadcast domains, and delivers up to 1 Tbps of aggregated bandwidth for future growth.
In a metropolitan service provider environment, the WS-C3850-48XS-F-S aggregates 10G customer circuits from multiple POPs into a resilient backhaul mesh. IP Base routing features enable MPLS-like VPNs and advanced QoS classification for voice, video and data services. Benefit: Optimizes bandwidth utilization, simplifies multi-tenant traffic isolation and accelerates service activation, driving higher revenue per fiber strand.
