Cisco ISR4331 Router (ISR4331-AX/K9)
The Cisco ISR4331-AX/K9 is an enterprise-class integrated services router designed for secure WAN edge deployments in branch and campus networks. Delivering 100Mbps to 300Mbps aggregate throughput, it consolidates routing, services, and application performance in a compact 1RU platform. Three onboard 10/100/1000 WAN/LAN ports plus dual SFP-based interfaces simplify mixed copper-fiber connectivity, while modular NIM and service-module slots allow flexible expansion across Asia, Europe, Africa, and North America.
