GIGABIT ETHERNET APPLICATIONS AND KEY FEATURES
Cisco Catalyst 6500 series mixed media/fiber-based gigabit Ethernet interface modules are used in distribution and core layers, data-center and Metro
Ethernet applications. These gigabit Ethernet interface modules deliver wire-speed switched connectivity and support several switch fabric
connections and traffic forwarding options, these include: Classic, CEF256, dCEF256 and CEF720. With a range of port densities and modular
physical layer interfaces, these modules also offer a choice of packet buffer depths for traffic shaping, and QoS granularity with varying number of
queues and drop threshold options. These key features are important aspects to in determining best module for a given network application (Table 1).
