Data Movement Processor (DMP)


A processor on the Cisco Catalyst 5000 series switch that, along with the multiport packet buffer memory interface, performs the frame-switching function for the switch. The DMP also handles translational bridging between the Ethernet and Fiber Distributed Data Interface (FDDI) interfaces, IP segmentation, and intelligent bridging with protocol-based filtering.
