Introduction

The Cisco 4000 family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. With amazing levels of built-in intelligent network capabilities and convergence,it specifically addresses the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources. But they often also have a growing need for direct communication with both private data centers and public clouds across diverse links,including Multiprotocol Label Switching (MPLS) VPNs and the Internet. The Cisco 4000 series ISRs consolidate many must-have IT functions,including network,compute,and storage resources. The high-performance,integrated routers run multiple concurrent IWAN services without slowing your data throughput.

Cisco ISR 4321 features modular network interfaces with diverse connection options for load-balancing and network resiliency and modular interfaces with online removal and insertion (OIR) for module upgrades without network disruption.
