Ideal Use Cases
Enterprise Campus Core
The C9500-24Y4C is purpose-built as a fixed core switch for enterprise campus networks, delivering 2.0 Tbps of non-blocking switching capacity and 25G high-density downlinks to support modern aggregation and distribution architectures.
Data Center Edge and Aggregation
With 4x 100G QSFP28 uplinks and EVPN/VXLAN support, this switch is well suited for data center edge and leaf-spine aggregation roles requiring high throughput and advanced routing features.
SD-Access Fabric Deployment
The C9500-24Y4C is a validated node for Cisco SD-Access, enabling policy-based automation, secure segmentation, and IoT integration across the campus fabric from a single management plane.
High-Density 25G Server Connectivity
Organizations migrating server access from 10G to 25G can consolidate connectivity at the top-of-rack or end-of-row layer, taking advantage of SFP28 backward compatibility with 10G and 1G optics.
MPLS and Segment Routing Backbone
With support for MPLS L2/L3 VPNs, BGP, OSPF, and Segment Routing, the C9500-24Y4C can serve as a high-performance backbone node in enterprises requiring advanced WAN and VPN interconnect capabilities.
Budget-Optimized Infrastructure Refresh
Enterprises refreshing aging core infrastructure can deploy a professionally refurbished C9500-24Y4C to achieve the performance of current-generation Cisco hardware at a substantially reduced capital cost.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The -A suffix denotes the Network Advantage license tier, while the -E suffix denotes the Network Essentials license tier. The underlying hardware is identical across both SKUs. The license tier determines which software features are enabled; advanced capabilities such as EVPN/VXLAN, Segment Routing, and full BGP typically require the Network Advantage license. WhaleyComm sells the base hardware unit — contact our team to confirm the license tier you require.
Yes. The Cisco C9500-24Y4C supports Cisco StackWise Virtual, which allows two physical switches to operate as a single logical switch for redundancy and simplified management. This capability is available on the Network Advantage license tier.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
