The BCM56502 is the fifth generation of the highly-integrated and costeffective StrataSwitch and StrataXGS product line and is a single-chip
solution with 24 GbE ports and two 10 GbE/HiGig+ uplink ports.
The ContentAware classification feature of the StrataSwitch and
StrataXGS has been further enhanced in the BCM56502 with unmatched
flexibility and programmability. The ContentAware engine can be used
for applications such as policy-based routing, access control lists,
dynamic adaptation to changes in virus threats, and so on.
The BCM56502 incorporates 24 GbE ports that can operate at
10⁄100⁄1000 Mbps. The uplink ports can operate in two modes: 10 GbE
switching mode and HiGig+ uplink mode. The integrated 10 GbE
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 multislot redundant chassis system.
With high-integration and high-port density, the BCM56502 family is
ideal for Enterprise applications in stand-alone, stackable, and chassis
configurations. The BCM56502 configurations are applicable in the
edge, aggregation, and core areas of the Enterprise. The BCM56502 is
also ideal for embedded switch applications like Blade Server Switch,
ATCA chassis, IPDSLAM, 3G Wireless Base Station, and others.
The BCM56502 integrates sophisticated, advanced L3 switching
features for cost-effective highly manageable Enterprise networks. The
BCM56502 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 BCM56502 has built-in security functions for highly secure
Enterprise networks including BroadSAFETM. 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
The BCM56502 integrates sophisticated metering, statistics, and traffic
management features, optimizing the QoS in the Enterprise networks for
voice, video, and data convergence. The BCM56502 also provides rateadjustable, hardware-based sFlow® implementation and flexible
multiple-session remote port-mirroring functionality for efficient
network management.
The BCM56502 switch supports a Broadcom Serial Controller (BSC) for
communicating with external devices such as serial EEPROM, flash
PROM memories, and parallel port devices. The BCM56502 also
supports a serial interface for the MII management of physical layer
The BCM56502 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 BCM56502 switch.
