Meet All Your Needs with Cisco ISR 4000 Models

Why You Choose Cisco ISR 4000 Series Router Today?
  1. Meet All Your Branch Needs with One Device
  2. Intelligent Services Reduce Bandwidth Costs
  3. Near-Instant IWAN Configuration

What Else? Prepare your branch site and protect it for the future with the Cisco 4000 Series ISR digital-ready platform now.

The Cisco ISR 4000 Series routers consolidate many must-have IT functions, including network, security, compute, storage, and unified communications. So you get everything you need in a single platform. The platform is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads.

The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps.

██ Highlights
  • Cisco IOS Universal Image (IP Base/SEC/UC/AX)
  • High-performance multicore processors for high-speed WAN connections and multiple services
  • Separates control- and data-plane operations (Cisco 4431/4451: the default control-plane memory is 4 GB, upgradable to 16 GB, and the default data-plane memory is 2 GB)
  • Cisco Enhanced Services Module (SM-X) and Cisco Network Interface Module (NIM) integrate networking, services, computing, and storage into a single form factor
