The BCM5673 10 Gigabit Ethernet switch is a scalable, multi-layer switch-on-chip member of the StrataXGS family. The BCM5673 is a dual port switch, which supports a 10 Gigabit Ethernet (IEEE802.3ae) port and a HiGigTM 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, port trunking, and mirroring functions across the stack. The HiGig port can be used to interconnect up to 32 switching devices, which enable highport density switching applications. The BCM5673 supports VLAN double tagging. The built-in Double Tagging Engine provides double tagging support to the entire StrataXGS family of products. The switch can also be used in loopback mode enabling double tagging support for the Gigabit Ethernet ports on the BCM5690. The built-in Fast Filter Processor (FFP) 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 firewall. The BCM5673 provides hardware support for IP multicasting as well as IP multicast replication. This enables a number of multicast applications, such as webtraining and audio/video conferencing. The BCM5673 supports advanced packet flow control, such as head-ofline blocking prevention and IEEE802.3x compatible full-duplex control.
