WS-C4948E Use Case
Campus Core Aggregation in Large-Scale Enterprise Environments
Deploy WS-C4948E-Catalyst 4948E as the central distribution switch in a multi-building campus network supporting 1,200+ end-users. Its 48 Gigabit Ethernet ports and four 10 GbE uplinks deliver non-blocking, low-latency L2/L3 switching with Hot-Standby Routing, ensuring seamless application delivery, predictable performance and simplified operations across enterprise segments.
Top-of-Rack Connectivity in SMB Data Centers
Use WS-C4948E as a Top-of-Rack (ToR) switch for virtualization-heavy small-to-medium data centers, aggregating up to 48 server NICs with four 10 GbE uplinks to the spine. This configuration optimizes east-west traffic, accelerates virtual machine mobility and boosts throughput by up to 480 Gbps, while delivering advanced QoS and VXLAN routing for scalable, secure multi-tenant workloads.
High-Definition IP Video Surveillance for Smart Campuses
Implement WS-C4948E to aggregate 48 IP cameras in a corporate or education campus, forwarding high-definition video streams to a centralized NVR farm. With wire-speed QoS, IGMP snooping and hardware-based ACLs, the switch enforces video-stream prioritization and secure segment isolation, reducing jitter and packet loss for reliable, continuous surveillance monitoring.
