BCM56580 Block Diagram

• Integrated XAUI™ SerDes for all 10-GbE ports

• Integrated single-lane SerDes for all 2.5-GbE ports

Strict priority scheduling

• Head of line blocking prevention

• Full-duplex flow control (802.3x)

• Line rate multifield packet classification

• Supports IEEE 802.1p, TOS/DiffServ, rate limiting, policing,

priority tagging, and remapping

• Extended security and ACL filtering
