48 10/100/1000 + Two 10-GbE + HiGig + Stackable

The BCM56304 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 four 10-GbE/HiGig+ uplink ports. The BCM56304 is a member of the value GbE product line, with a corresponding pin-compatible member in the feature GbE product line—BCM56504. The BCM56304 incorporates 24 GbE ports that can operate 10/100/1000 Mbps. The uplink ports can operate in two modes:?10 GbE switching mode ?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 BCM56304 family is ideal for Enterprise applications in standalone, stackable, and chassis configurations. The BCM56304 configurations are applicable in the edge, aggregation, and core areas of the Enterprise. The BCM56304 is The ContentAware classification feature of the StrataSwitch and

StrataXGS has been further enhanced in the BCM56304 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 BCM56304 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 BCM56304 integrates sophisticated metering, statistics, and traffic management features, optimizing the QoS in the Enterprise networks for voice, video, and data convergence. The BCM56304 also provides rate adjustable hardware based sFlow implementation and flexible multiple session remote port mirroring functionality for efficient network management.
