BCM56224 Block Diagram
The BCM56224 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 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 hardware-
based scheme supports highly manageable L3 networks and enables cost-
effective 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 multiple-
session 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.
Product ordering information:
• BCM56224 (24 GbE + 4 × 1 Gb/2.5 Gb)
