​​Core Specifications and Hardware Design​​

• ​​20x 10G/25G/40G Ports​​: Flexible interfaces for high-speed LAN/WAN aggregation.
• ​​6x 100G QSFP28 Slots​​: Supports high-bandwidth backbone or data center interconnects.
• ​​Modular Chassis​​: Allows expansion with additional service modules (e.g., firewall, encryption).
• ​​Redundant Power Supplies​​: Ensures 99.999% uptime for mission-critical deployments.

​​Performance and Scalability​​

The ​​C8500-20X6C​​ is engineered for ​​multi-terabit throughput​​, making it ideal for:

• ​​SD-WAN Hub Deployments​​: Manages thousands of branch connections with sub-50ms latency.
• ​​5G Edge Networks​​: Processes high-volume mobile traffic with deep buffer capacity.
• ​​Hyperscale Security​​: Integrates Cisco Secure Firewall and encrypted traffic analytics (ETA) without performance degradation.

​​Key Differentiators vs. Competing Platforms​​

• ​​Unified SD-WAN and Routing​​: Combines Catalyst SD-WAN and IOS XE for simplified operations.
• ​​Application Hosting​​: Runs third-party containers or custom apps directly on the router.
• ​​Energy Efficiency​​: Consumes 30% less power than comparable chassis-based systems.

​​Addressing Common Deployment Concerns​​
