Cisco ISR 4321 (2GE,2NIM,4G FLASH,4G DRAM,IP Base) Overview
ISR4321/K9 Overview
Cisco 4321 Integrated Services router is design to deliver advanced services to the small enterprise branch environment. It delivers 50Mbps thoughtput by default. With pay-as-you-grow performance, you can increase forwarding capacity to 100Mbps by buying FL-4320-PERF-K9 licenses.
