3Com SuperStack 3 Switch 3870 delivers wirespeed Gigabit Ethernet switching, with ten times the performance of 10/100 desktop switching but at similar prices. Tri-speed operation of the switch enables backward compatibility with existing devices, such as printers, while still allowing new PC's and servers to operate at their maximum potential.

This switch also has notable investment protection capabilities. Along with the built-in 10Gbps stacking ports, each Switch 3870 also has an expansion slot capable of supporting an additional 10Gbps full duplex (20Gbps total) high-speed Ethernet connection. And, the switch silicon supports multilayer (Layers 2 / 3 / 4) switching.
