What Is the CP-840S-BUN-K9? Bundle Features, Scalability, and Deployment Use Cases

Product Overview

The ​​CP-840S-BUN-K9​​ is a ​​scalable, security-focused bundle​​ for Cisco’s Catalyst 8400 Series Integrated Services Routers. Designed for enterprises requiring advanced threat protection and high availability, this pre-configured kit includes hardware, software, and licenses optimized for ​​SD-WAN, zero-trust networking, and multi-cloud gateways​​.

Bundle Components and Specifications

• ​​Hardware​​: Catalyst 8400 chassis (8-slot), ​​2 x C8400-SUP-2T​​ supervisors (dual-CPU), ​​2 x C8400-DC-PWR​​ 2200W power supplies
• ​​Software​​: ​​Cisco IOS XE 17.12.1+​​ with ​​DNA Premier 7-year license​​ and ​​Secure Firewall Threat Defense​​
• ​​Connectivity​​: ​​1 x C8400-16X10GE​​ module (16-port 10GE) + ​​1 x C8400-4Q40GE​​ (4-port 40GE QSFP+)
• ​​Security Add-ons​​: ​​Encrypted Traffic Analytics (ETA)​​, ​​Cisco Talos Threat Intelligence​​, and ​​MACsec 256-bit encryption​​

Key Deployment Scenarios

​​1. High-Security Branch Offices​​
Combines ​​SD-WAN segmentation​​ with ​​on-device firewall​​ to isolate sensitive traffic (e.g., PCI-DSS compliance for retail).

​​2. Multi-Cloud Interconnect Hubs​​
Supports ​​AWS Transit Gateway and Azure Virtual WAN​​ integration, reducing latency for SaaS applications like Salesforce or Workday.

​​3. Distributed Enterprise Edge​​
Scales to ​​20 Gbps encrypted throughput​​, ideal for manufacturing sites with IoT/OT convergence and real-time SCADA systems.

Addressing Critical User Questions

​​Q: Does the DNA Premier license include SD-WAN capabilities?​​
A: Yes—covers ​​Cisco vManage orchestration​​, ​​Application Visibility and Control (AVC)​​, and ​​SaaS optimization​​ for Microsoft 365/Teams.

​​Q: Can existing Catalyst 8300 modules be used in this chassis?​​
A: No—the ​​Catalyst 8400 Series​​ uses enhanced ASICs for higher throughput; modules are not backward-compatible with 8300/8500 platforms.

​​Q: What redundancy features mitigate downtime risks?​​
A: ​​Stateful switchover (SSO)​​ for supervisors + ​​PSU load sharing​​ ensures <50ms failover during power or link disruptions.

Operational Insight

The ​​CP-840S-BUN-K9​​ shines in environments where security and scalability can’t be compromised, but its 7-year license lock-in demands long-term commitment. While smaller businesses might balk at the upfront cost, enterprises managing regulated data or multi-cloud footprints will find its ​​embedded threat defense​​ and ​​40GE readiness​​ justify the investment—provided IT teams are trained to leverage its full stack of features. Just ensure your power infrastructure can handle its 1800W peak draw during full encryption loads.
