BCM5346M
Enables a new generation of lower-cost switches with Gigabit
Ethernet connectivity and much smaller form factors.
Complete switch on a chip integrates multilayer forwarding
and filtering logic and internal ARL tables and packet
buffering.
Filters and forwards traffic at full wire speed on all 16 ports at
all layers of functionality. This equates to 32 Gbps of
bandwidth.
Provides the most cost effective Gigabit Ethernet connectivity
to the desktop for all remote and branch office as well as
enterprise workgroup needs.
Supports 8K internal MAC addresses so even large, segmented
networks can be supported.
Supports Quality of Service (QoS) for prioritization of
different traffic types.
Full support of VLANs allows separation of user groups and
minimizes superfluous traffic.
Jumbo frame support allows the device to be connected to
corporate server farms and networks while maintaining
maximum TCP/IP performance.
Supports the latest standards used in corporate networks for
discovery, management, access control, and traffic control.
On-chip MIB registers allows the collection and transmission
of statistics for each port and allows an upward migration path
for corporate users.
