The BCM56303 is the fifth generation of the highly-integrated and cost-
effective Broadcom StrataSwitch and StrataXGS product line in a single-
chip solution with 24 GbE ports and three 10-GbE/HiGig+ uplink ports.
The BCM56303 is a member of the Value GbE product line, with a
corresponding pin-compatible member in the Feature GbE product
line—BCM56503. The BCM56303 incorporates 24 GbE ports that can
operate 10/100/1000 Mbps. The uplink ports can operate in two modes:
• 10GbE switching mode
• HiGig+ uplink mode
The integrated 10GbE switching ports are CX-4 compliant XAUI
interfaces. The HiGig+ uplink interface is used to connect to other
StrataXGS devices in a larger stacking system or to the BCM5675/
BCM5676 Switch Fabric via a backplane in a multi-slot redundant
chassis system.
With high-integration and high-port density, the BCM56303 family is
ideal for Enterprise applications in standalone, stackable, and chassis
configurations. The BCM56303 configurations are applicable in the
edge, aggregation, and core areas of the Enterprise. The BCM56303 is
also ideal for embedded switch applications like a Blade Server Switch,
ATCA chassis, IPDSLAM, 3G Wireless Base Station, and others.
The BCM56303 integrates sophisticated advanced L3 switching features
for cost-effective highly-manageable enterprise networks. The
BCM56303 performs IPv6 routing and transition services in hardware,
allowing IT managers to deploy L3 switches that are future-proof, highly
manageable L3 networks, and enable cost-effective transition from IPv4
to IPv6.
The ContentAware classification feature of the StrataSwitch and
StrataXGS has been further enhanced in the BCM56303 with unmatched
flexibility and programability. The ContentAware engine could be used
for applications such as policy-based routing, access control list,
dynamic adaptation to changes in virus threats, and so on.
The BCM56303 has built-in security functions for highly secure
Enterprise networks including BroadSAFE^TM. Utilizing hardware-based
identity management and authentication coupled with key management
software that directs and manages clients, BroadSAFE Security provides
exceptionally strong network security without impacting network
performance.
The BCM56303 integrates sophisticated metering, statistics, and traffic
management features, optimizing the QoS in the Enterprise networks for
voice, video, and data convergence. The BCM56303 also provides rate
adjustable hardware based sFlow implementation and flexible multiple
session remote port mirroring functionality for efficient network
management.
The BCM56303 switch supports an I²C controller for communicating
with external devices such as serial EEPROM, flash PROM memories,
and parallel port devices, and also supports a serial interface for the MII
management of physical layer devices.
The BCM56303 switch interfaces to a host CPU via a 32-bit PCI bus
running at up to 66 MHz. Bus mastering and advanced DMA is
supported for efficient exchange of packet data between CPU memory
and the BCM56303 switch.
