•
•
•
•
switches with 10 Gigabit Ethernet support
Built-in double VLAN tagging enables seamless integration of
enterprise networks and service provider networks.
Provides hardware support for a number of multicast
applications, such as video and audio conferencing, web
training
Multiple classes of service (CoS) enable the switch to prioritize
latency-sensitive applications, such as VoIP and video
applications
Built-in 10 Gigabit Ethernet/XAUI SerDes, in addition to
integrated data and address memory, reduces overall system
cost and design complexity
Broadcom Switch API compatibility enables software reuse
and faster time to market
Small package and low-power enables cost effective and high
performance system design
Supports wire speed switching for all packet sizes, including
jumbo frames (up to 9 KB)
•

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.
