C9500-24Y4C-A Use Case
Enterprise Campus Core Aggregation with Cisco Catalyst 9500-24Y4C-A
A global financial services firm deploys the Catalyst 9500-24Y4C-A as its campus core switch to aggregate 24×25 GbE access links with 4×100 GbE uplinks to its data center. Leveraging Cisco DNA Center automation and built-in segmentation, the network delivers 40% higher throughput, sub-millisecond latency for real-time trading applications, and simplified policy enforcement. Outcome: accelerated digital transformation, predictable performance at scale, and reduced operational costs.
Cloud Data Center Spine–Leaf Fabric Using Catalyst 9500-24Y4C-A
A hyperscale cloud provider implements the Catalyst 9500-24Y4C-A as a spine node in a leaf–spine fabric. Each leaf switch connects over 25 GbE to server racks while the Catalyst 9500’s four 100 GbE uplinks link to the core. Hardware-based VXLAN routing and real-time telemetry enable seamless east-west traffic forwarding with sub-millisecond latency and support for 10,000+ VMs. Outcome: elastic scaling, high-performance interconnect, and robust multitenant microsegmentation.
Metro Edge Aggregation for 5G Backhaul and Enterprise WAN
A Tier-1 service provider installs the Catalyst 9500-24Y4C-A at its metro PoP to aggregate 5G O-RAN base stations and enterprise MPLS links over 25 GbE, with 4×100 GbE uplinks to the core network. Built-in Segment Routing and zero-touch provisioning reduce service turn-up times by 70%, while wire-speed IPv6/MPLS forwarding ensures low-latency MEC and SD-WAN services. Outcome: rapid service delivery, SLA-grade performance, and simplified operations.
