BCM5345M

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 wirespeed on all 24 ports at

all layers of functionality. This equates to 48 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.
