​​Core Features and Use Cases​​

The ​​C931-4P​​ provides ​​4x Gigabit Ethernet ports​​ and supports ​​up to 100 Mbps throughput​​, making it ideal for locations requiring reliable WAN connectivity without complex infrastructure. Key strengths include:

• ​​Integrated Security​​: ​​Cisco IOS XE​​ with ​​VPN (IPsec, DMVPN)​​ and ​​firewall​​ capabilities protects against unauthorized access.
• ​​Zero-Touch Deployment​​: Pre-configured templates simplify setup for distributed retail chains or franchise networks.
• ​​PoE Passthrough​​: One port delivers ​​30W PoE​​, powering devices like IP phones or small access points without extra injectors.

​​Technical Specifications and Performance​​

• ​​WAN Flexibility​​: Supports ​​DSL, LTE, or Ethernet​​ uplinks for failover redundancy.
• ​​QoS Prioritization​​: Ensures stable VoIP and video conferencing traffic even on limited bandwidth.
• ​​Compact Design​​: ​​Rack-mountable 1RU form factor​​ suits space-constrained environments like kiosks or clinics.

​​Addressing Critical User Questions​​

​​Q: Can it handle multiple VPN tunnels simultaneously?​​
A: Yes. The router supports ​​up to 5 IPsec VPN tunnels​​, sufficient for small branches connecting to HQ or cloud services.

​​Q: Is it compatible with Cisco SD-WAN?​​
A: No. The ​​C931-4P​​ is designed for standalone deployments. For SD-WAN, consider the ​​Cisco Catalyst 8300 series​​.

​​Q: How does it perform in high-traffic scenarios?​​
A: With ​​100 Mbps throughput​​, it’s best suited for sites with ≤20 users. For heavier loads, upgrade to the ​​C1111-4P​​ model.

​​Ideal Deployment Scenarios​​

• ​​Retail Stores​​: Connects POS systems, inventory databases, and security cameras via PoE.
• ​​Remote Clinics​​: Secures patient data transfers with ​​AES-256 encryption​​ over VPN.
• ​​Temporary Sites​​: Plug-and-play setup supports pop-up offices or construction trailers.
