OVERVIEW

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.

FEATURES
• One 10 Gbps IEEE 802.3ae compliant Ethernet port
• One HiGig™ port configurable for 10 Gbps speed
• Integrated on-chip 512 KB packet buffer memory
• Integrated on-chip layer 2/3 tables
• Supports wire speed switching for all packet sizes, including jumbo frames (up to 9 KB)
• Supports eight class of service (CoS) queues
• Supports advanced packet flow control:
    • Head-of-line blocking prevention
    • Full-duplex flow control (IEEE 802.3x compatible)
• ContentAware™ network processing per port:
    • Line rate deep packet classification
    • Supports IEEE 802.1p, ToS/DiffServ, rate limiting, policing, priority tagging, and re-mapping
• Provides hardware support for IP multicast and IP multicast replication
• Support for double VLAN tagging with loopback feature
• Support for 128 StrataXGS™ devices using module remapping
• Supports port mirroring across the stack
• Feature parity with BCM5695 multilayer switch
• Low power ~4 W
