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. The Cisco ISR4451-X-V/K9 is the 4451 Voice(V) Bundle.
Table 4 shows the comparison between ISR4451-X-V/K9 and ISR4351-V/K9.
