Cisco Catalyst 9500 Network Switches

Steel City Consulting is an official Cisco Partner.

Cisco Catalyst 9500 Series (C9500) switches are purpose-built fixed core and aggregation switches for enterprises and data centres. The C9500 family leads the Catalyst 9000 line with high throughput, advanced programmability, and enterprise-grade resiliency, making it a foundation for campus core and distribution layers.

  • High-performance programmable switching: Based on Cisco’s UADP 3.0 (standard C9500) or Silicon One Q200 ASIC (C9500X), C9500 platforms provide up to 3.2 Tbps (per ASIC) and advanced forwarding pipelines for core data fabric operations.

 

  • Rich routing, VPN & fabric capability: Support for MPLS, L2/L3 VPN, Multicast VPN (MVPN), VRF, SD-Access (LISP, host tracking), and advanced virtualisation make the C9500 suitable for large enterprise campus and data centre edge fabrics.

 

  • High availability & redundancy architecture: Dual, platinum-rated redundant power supplies, variable-speed redundant fans, and support for Nonstop Forwarding / Stateful Switchover (NSF/SSO) ensure continuous operation in mission-critical environments.

 

  • Secure, cloud-ready, software-defined infrastructure: With MACsec encryption, Secure Boot, and full integration with Cisco DNA Center & catalyst software subscriptions, the C9500 enables secure programmable networks that scale across on-premises and cloud.

Customer FAQ: Cisco Catalyst 9500

Upgrading to C9500 network switches? Our FAQ answers 6 common questions.

Q1. What are the main advantages of moving from Catalyst 6800 or C4500 to the C9500?
Catalyst 9500 delivers significantly higher port speeds (10/25/40/100G vs 1/10G on older platforms) and greater route scale (up to 2M IPv4 entries). Plus, support for modern overlays such as EVPN and VXLAN, and tighter integration with Cisco DNA Center for automation. This positions the C9500 as both a direct successor and a long-term platform for campus and aggregation roles.

 

Q2. How does the Cisco C9500 compare to C3850 and C4500-X-LE switches?

FactorCatalyst 9500Catalyst 3850 / 4500-X-LE
Switching capacityUp to 6.4 Tbps (StackWise Virtual)~480 Gbps (limited stacking)
Routing / MAC scaleLarge tables (MPLS, SD-Access, 2M+ routes)Smaller scale, fewer features
Uplinks1/10/25/40/100G optionsMostly 1/10G only
Security & featuresUADP ASIC, MACsec, DNA Center integrationLimited modern security/SDN
Migration fitModern enterprise core/aggregation

Legacy campus/core

Answer: Cisco’s C9500 offers higher bandwidth, flexible uplinks, and advanced security / automation,  making it the natural upgrade path from Catalyst C3850 or C4500-X-LE network switches.

Q3. How scalable is the C9500 in terms of routing and fabric size?
The Catalyst 9500 offers broad scalability: route scale up to 2M IPv4 entries, support for thousands of VRFs, and advanced segmentation for SD-Access and VPN services. Higher-end C9500X models deliver larger buffer capacity and higher route scale, making them suitable for large campus cores or data centre edge roles.

 

Q4. How does licensing and software model work for the C9500?
Cisco uses a software subscription model with Cisco DNA and Catalyst Software subscriptions. Base hardware licenses (Network Essentials / Advantage) are perpetual. Cisco recommends combining these with Cisco DNA for full automation and analytics capabilities.

 

Q5. Can I run SD-Access fabrics on Catalyst C9500?
Yes. The Catalyst 9500 line includes support for SD-Access features such as host tracking database, VRF-aware LISP, and cross-domain connectivity. These features rely on compatible software images. 

 

Q6. What high-availability features should enterprises expect from C9500?
Cisco C9500 switches support critical resiliency capabilities: NSF/SSO (Nonstop Forwarding with Stateful Switchover) for control-plane failover, redundant power supplies and fans, and support for in-service upgrades and patching. These capabilities allow core/aggregation deployments to achieve minimal downtime and seamless upgrades.
