Frequently Asked Questions (FAQs)

What is the primary throughput capacity of the Cisco ISR4351/K9 router? +
The Cisco ISR4351/K9 is designed for branch office environments, offering a high-performance architecture that provides up to 200 Mbps of aggregate throughput. This performance can be scaled up to 400 Mbps through a simple performance-on-demand license, ensuring that your network infrastructure can grow alongside your bandwidth requirements without requiring a complete hardware replacement.
Does the ISR4351/K9 support modular interface options for custom network connectivity? +
Yes, this platform features three Network Interface Module (NIM) slots and one Service Module (SM) slot. These modular bays allow you to integrate various connectivity options, including T1/E1, serial, and switching modules, providing the flexibility needed to tailor the router's physical interface density to your specific branch site requirements.
How does the ISR4351 manage branch office security and encryption performance? +
Security is integrated directly into the router's architecture with dedicated hardware acceleration for IPsec VPN encryption. By offloading these intensive cryptographic tasks to the hardware rather than the main processor, the ISR4351 maintains consistent, high-speed data transmission even when running complex encrypted tunnels and stateful firewall inspection policies across your WAN.
What type of software licensing model is used for the Cisco ISR4351/K9? +
This router utilizes Cisco’s Software-Defined WAN (SD-WAN) and IOS XE licensing structure. You can activate various feature sets, such as Security or Unified Communications, by applying specific licenses to the base system. This allows for a modular feature deployment where you only pay for the software capabilities and throughput performance tiers that your specific branch office currently requires.
Can the ISR4351 be integrated into an existing Cisco SD-WAN deployment? +
Absolutely. The ISR4351/K9 is fully compatible with Cisco SD-WAN solutions, allowing it to function as a core component of a modern, policy-driven network fabric. Once updated to the appropriate IOS XE software version, it can be provisioned and managed centrally to optimize path selection and application performance across your distributed enterprise network.
What are the power requirements and redundancy options for this unit? +
The ISR4351/K9 features a dual, internal power supply configuration that provides excellent hardware redundancy. If one power source fails, the secondary supply ensures continuous operation, which is critical for maintaining uptime in branch locations where physical access for repairs might be delayed. It is designed to fit standard rack mount configurations, requiring minimal cabinet space.
How does the multi-core architecture improve performance on the ISR4351? +
Unlike traditional routers, the ISR4351 utilizes a multi-core processor architecture that separates the control plane from the data plane. This design ensures that management tasks, such as routing table updates and administrative processes, never interfere with packet forwarding performance. This separation guarantees consistent network latency and jitter-free operation for sensitive applications like VoIP and video conferencing.
Is the ISR4351/K9 suitable for high-density voice gateway applications? +
The ISR4351 is an excellent choice for branch voice services. With the addition of appropriate voice interface modules, it acts as a robust gateway for digital and analog voice trunks. The hardware is optimized to handle voice processing tasks efficiently, making it a reliable foundation for integrated communication systems that need to bridge traditional telephony with modern IP-based infrastructure.
How can I obtain a bulk quote for multiple ISR4351 units for my enterprise rollout? +
