ISR4451-X/K9 Overview Cisco 4451 Integrated Services Router, named as ISR4451-X, which supports 2 Enhanced service-module (SM-X) slots, delivers 1 Gbps to 2Gbps aggregate throughput. This router also supports two kinds of DDRM, data plane and control/services plane, which make administrator easy to manage the router.
