The Cisco® SM-X Layer2/3 EtherSwitch® Service Module can reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) ports within the Cisco 4451-X and Cisco 3900 and 2900 Series Integrated Services Routers (ISRs). This integration allows network administrators to manage a single device using Cisco management tools or the router command-line interface (CLI) for LAN and WAN management needs. This approach reduces network complexity, lowers maintenance contract costs, lessens staff training needs, simplifies software qualification efforts, increases availability, and delivers a consistent user experience at branch offices and headquarters.
