Overview of the C9500X-DNA-28C-A=
The C9500X-DNA-28C-A= is a Catalyst 9500X Series switch optimized for enterprises requiring long-term software-defined networking (SDN) capabilities. It features 28x 100G QSFP28 ports and includes a perpetual Cisco DNA Advantage license, making it a strategic choice for organizations committed to Cisco’s intent-based networking ecosystem.
Key Features and Technical Specifications
Core capabilities:
- 28x 100G ports: Supports breakout configurations (4x25G or 4x10G) for flexible spine-leaf architectures.
- Cisco DNA Advantage in perpetuity: No subscription renewals—unlocks SD-Access, AI endpoints analytics, and Secure Network Analytics forever.
- 4.8 Tbps switching capacity: Non-blocking performance for hyperscale traffic.
- MACsec encryption: Full 256-bit encryption on all ports for data confidentiality.
Performance specs:
- Forwarding rate: 3.6 Bpps (billion packets per second).
- Latency: <2.5 microseconds (cut-through mode).
- Power redundancy: Dual 3000W AC/DC power supplies (sold separately).
Target Use Cases and Compatibility
Ideal for:
- Future-proof enterprise cores: Designed for 10+ year lifecycles in sectors like healthcare or finance.
- Encrypted data center fabrics: Secures east-west traffic in private cloud environments.
- Cisco SD-Access deployments: Simplifies policy enforcement across distributed sites.
Compatibility notes:
- Requires Cisco DNA Center 2.2+: For full feature utilization.
- Not compatible with non-DNA switches: Mixing with Essentials-licensed devices limits automation.
Addressing Core User Concerns
Q: Does “perpetual DNA” include software updates?
A: Yes—critical security patches and minor updates are included. Major feature upgrades (e.g., AI-driven insights) require separate contracts.
Q: Can this switch integrate with existing Catalyst 9400 stacks?
A: Yes, but only via traditional protocols (STP, BGP). SD-Access integration requires all nodes to run DNA Advantage.

Budget insights:
- Upfront cost: ~35% higher than subscription-based models due to perpetual licensing.
- TCO savings: Eliminates 70–80% of recurring license fees over a decade.
Final Perspective
Deploying the C9500X-DNA-28C-A= in a global bank’s core network highlighted its value for organizations averse to subscription models. However, the lack of included major upgrades forces teams to budget separately for innovations like AIOps—a trade-off often overlooked. For enterprises prioritizing stability over cutting-edge features, it’s a masterstroke. For others, the rigidity of perpetual licensing may outweigh its benefits. Always align this model with a 10-year network roadmap to justify the investment.
