Cisco RSP720-3CXL-GE= enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco RSP720-3CXL-GE= is a Route Switch Processor 720 (RSP720) for the Cisco 7600 Series router, combining route processing and switch fabric on a single supervisor-class module with 720 Gbps of fabric capacity and the PFC3CXL (Policy Feature Card 3, extra-large TCAM) forwarding engine, connecting to the chassis via Gigabit Ethernet uplinks. The RSP720 was the high-end supervisor option for the 7600, aimed at service-provider and large-enterprise deployments running MPLS, large routing tables or high port density that exceeded what the earlier Supervisor 720 could support, with the 3CXL variant specifically sized for the largest forwarding tables in the range. The Cisco 7600 was a mainstay service-provider edge and MPLS PE router through the 2000s and 2010s, and a meaningful installed base remains in service, where a spare RSP720 is a significant but necessary stock item given the module’s role as the chassis’s brain. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
