It is a single-chip solution with a high-performance 32-bit MIPS CPU and 28 GbE ports, where four of the GbE ports can also be configured to run as 2.5 Gb uplinks. The BCM56224 is a member of the Enterprise Value GbE product line. The BCM56224 incorporates 28 GbE ports that can operate at 10/100/1000 Mbps; four of them can operate at 2.5 Gb, ideal for low-cost stacking or uplink. The HGL uplink interface is used to connect to other devices via low-cost standard CAT-7 cables in the BCM56224 to create a larger stacking system. With high integration and high port density, the BCM56224 is ideal for enterprise applications in stand-alone and stackable configurations. The BCM56224 enables cost-effective GbE to the desktop in the enterprise and is also ideal for embedded switch applications like a Blade server switch, ATCA chassis, IPDSLAM, 3G wireless base station, and others. The BCM56224 conducts wirespeed L2 switching and L3 routing for cost-effective highly manageable enterprise networks. The BCM56224 performs IPv6 routing and transition services in hardware, allowing IT managers to deploy L3 switches that are future-proof. This hardwarebased scheme supports highly manageable L3 networks and enables costeffective transition from IPv4 to IPv6. The TCAM-based ContentAware™ classification engine of the StrataSwitch® and StrataXGS devices is further enhanced in the BCM56224 with increased flexibility and programmability. The ContentAware engine can be used for applications such as policy-based routing, access control list management, and dynamic adaptation to changes in virus threats. The BCM56224 integrates sophisticated metering, statistics, and traffic management features, optimizing the Quality of Service (QoS) in the enterprise networks for voice, video, and data convergence. The BCM56224 also provides rate-adjustable hardware-based sFlow® implementation and flexible multiplesession remote port mirroring functionality for efficient network management. The BCM56224 switch integrates a high-performance 32-bit MIPS CPU, ideal for low-cost SoCs in fixed or stackable configurations. The highly integrated BCM56224 is cost-optimized for system level BOMs. The BCM56224 can also be managed by an external CPU via one of these host interfaces: • 32-bit PCI bus • 16-bit EB bus • GbE with GMII Bus mastering and advanced DMA are supported for efficient exchange of packet data between CPU memory and the BCM56224.
