ISR4351-V/K9 Routers Overview
The Cisco ISR4351-V/K9 is designed for mid-size to large enterprise branch environments, offering advanced services and unparalleled WAN intelligence with VOIP features. It delivers scalability, high performance, network services, and security, making it ideal for running multiple services. With features like Voice, AVC, performance routing (PfR), and WAAS, the ISR4351-V/K9 goes beyond just routing, offering intelligent network traffic management. It supports OnePK and AppNav for streamlined network and application integration. The router provides 200 Mbps to 400 Mbps performance on demand, with a pay-as-you-grow model that allows for performance scaling as needed. Additionally, the ISR4351-V/K9 introduces service containers, using dedicated CPU, memory, and storage to integrate network services without extra modules. The router includes 3 onboard WAN or LAN 10/100/1000 ports, 3 RJ-45-based ports, 3 SFP-based ports, 2 enhanced service-module (SM-X) slots, 3 NIM (Network Interface Modules) slots, and 1 onboard ISC slot for flexible expansion. It offers 4 GB RAM (expandable to 16 GB) and 4 GB flash memory (expandable to 16 GB) to meet the demands of growing networks. With internal AC, DC (roadmap), and PoE power supply options, plus a rack-mountable 2RU form factor, the ISR4351-V/K9 is perfect for Cisco Enterprise Branch Routers, offering service module support, network interface module support, ISC onboard, and SFP-based connectivity.
