OVERVIEW
The BCM56101 is the fifth generation of the highly-integrated and costeffective Broadcom StrataSwitch and StrataXGS product line in a singlechip solution, with 24FE , two GE, and one 10-GbE/HiGig+ uplink ports. The uplink port can operate in two modes:
    • 10-GbE switching mode
    • HiGig+ uplink mode
The integrated 10-GbE switching port is a CX-4 compliant XAUI interface. 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.
