The BCM56501 is the fifth generation of the highly-integrated and costeffective StrataSwitch and StrataXGS product line. The BCM56501 is a
single-chip solution with four 10-GbE/HiGig+ uplink ports.
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 multi-slot
redundant chassis system.
With high-integration and high-port density, the BCM56501 family is
ideal for Enterprise applications in standalone, stackable, and chassis
configurations applicable in the edge, aggregation, and core areas of the
Enterprise. The BCM56501 is also ideal for embedded switch
applications like Blade Server Switch, ATCA chassis, IPDSLAM, 3G
Wireless Base Station, and others.
The BCM56501 integrates sophisticated advanced L3 switching features
for cost-effective highly manageable enterprise networks. The
BCM56501 performs IPv6 routing and transition services in hardware,
allowing IT managers to deploy L3 switches that are future-proof, highly
manageable L3 networks to enable cost-effective transition from IPv4 to
The ContentAware classification feature of the StrataSwitch and
StrataXGS has been further enhanced in the BCM56501 with unmatched
flexibility and programability. The ContentAware engine can be used for
applications such as policy-based routing, access control list, dynamic
adaptation to changes in virus threats, and so on.
The BCM56501 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 BCM56501 integrates sophisticated metering, statistics, and traffic
management features, optimizing the QoS in the Enterprise networks for
voice, video, and data convergence. The BCM56501 also provides rateadjustable, hardware-based sFlow implementation and flexible multiplesession remote port-mirroring functionality for efficient network
The BCM56501 switch supports an I2C controller for communicating
with external devices such as serial EEPROM, flash PROM memories,
and parallel port devices. The BCM56501 also supports a serial interface
for the MII management of physical layer devices.
The BCM56501 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 BCM56501 switch.
