The BCM56228 is a highly integrated and cost-effective multilayer Ethernet switch from the Broadcom StrataXGS product line. It is a single-chip solution with a high-performance 32-bit MIPS CPU and 12 GbE ports, where four of the GbE ports can also be configured to run as 2.5 GbE uplinks.The BCM56228 is a member of the Enterprise Value GbE product line. The BCM56228 incorporates 12 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 BCM56228 to create a larger stacking system.With high integration and high port density, the BCM56228 is ideal for enterprise applications in stand-alone and stackable configurations. The BCM56228 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 BCM56228 conducts wirespeed L2 switching and L3 routing for cost-effective highly manageable enterprise networks.The BCM56228 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 BCM56228 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.
