ISR4321-AX/K9 intelligent WAN bundle combines security features, application experience and Wide Area Application Services (WAAS) features together into one platform. The intelligent WAN bundle optimizes network traffic across the “best” link based on applications and monitors network conditions to deliver the best performance as possible. In this platform, you get tight control over application performance, bandwidth usage, data privacy, and availability of your WAN links - control that you need as your branches conduct greater volumes of mission-critical business.

ISR4321-AX/K9 comes with IP base image, Security, AppX licensing for 200 TCP connection resources for ISR WAAS optimization and 4-GB DRAM, 4GB Flash memory, 50Mbps WAN bandwidth by default, to enable the ISR WAAS service, update memory, flash memory and hard drive is required, vWAAS service is not available on this platform.
