The BCM5674 10-Gigabit Ethernet switch is a scalable, multilayer

switch-on-chip member of the StrataXGS family. The BCM5674 is a

dual-port switch, which supports a 10 Gigabit Ethernet (IEEE 802.3ae)

port and a HiGig™ uplink port. The 10 Gigabit Ethernet port can be

used to interface to the XENPAK module via the XAUI interface.

The HiGig uplink expansion port supports explicit priority and

mirroring functions across the stack. The HiGig port can be used to

interconnect up to 128 switching devices, which enables high port

density switching applications.

The BCM5674 supports VLAN double tagging that is compatible with

other StrataXGS™ devices. The switch can also be used in loopback

mode enabling VLAN double tagging support for the Gigabit Ethernet

ports on the BCM5695.

The built-in Fast Filter Processor (FF) provides ContentAware™

network processing. The FFP supports functions such as ToS/DiffServ

mapping, rate limiting, policing, priority tagging, and metering

functions. The enhanced packet classification feature of the FFP enables

cutting-edge applications such as VoIP and firewalls.

The BCM5674 provides hardware support for IP multicast as well as IP

multicast replication. This enables a number of multicast applications,

such as Web training and audio/video conferencing.

The BCM5674 supports advanced packet flow control, such as head-of-

line blocking prevention and IEEE 802.3x compatible full-duplex

control.
