WS-C4928-10GE Use Case
High-Density Data Center Leaf Switch for East-West Traffic
In a hyperscale data center environment, the WS-C4928-10GE-CATALYST 4928 28X 1GBASE-X SFP 2X 10GBASE-X (no PSU) is deployed as a leaf switch to aggregate server top-of-rack uplinks. Leveraging 28 1GBASE-X SFP ports for VM-to-VM traffic and two 10GBASE-X leaf-to-spine uplinks, this solution delivers low-latency connectivity and scalable bandwidth growth. Outcome: 40% reduction in east-west latency, seamless capacity expansion to 10-fold spine fabrics, and simplified port-density management under a unified Cisco IOS-XE platform.
Campus Core Aggregation with Modular 10G Uplinks
For large enterprise campus networks requiring high availability and QoS assurance, the WS-C4928-10GE-CATALYST 4928 functions as a core aggregation switch. It consolidates departmental edge switches over 1GBASE-X SFP links and uplinks to distribution routers via dual 10GBASE-X SFP+ ports. Outcome: 99.999% network uptime with VRRP and HSRP support, streamlined multicast video distribution, and a 60% decrease in aggregated link oversubscription, all managed through Cisco DNA Center for enhanced policy enforcement.
Remote Branch SD-WAN Aggregation for Hybrid WAN
In a multi-site SD-WAN deployment, the WS-C4928-10GE-CATALYST 4928 aggregates local LAN segments and connects to dual 10G Internet or MPLS circuits using 10GBASE-X SFP+ transceivers. Integrated 1GBASE-X SFP ports link PoE switches, IP phones, and security appliances at the branch edge. Outcome: 50% improvement in application performance via intelligent path selection, zero-touch provisioning with Cisco vManage, and a consolidated footprint that reduces rack space by 30%.
