29.1 3-Port Ethernet Switch Features
Freescale Semiconductor, Inc.
•
• Three port switch with a fourth DMA bypass port
• Can be configured to operate as a 3-Port Switch (Switch Mode) or as two independent
• Filters and forward traffic at wire-speed on all ports
• Per-queue tail-drop congestion management
• Implements hardware switching look-up mechanism providing a learning capacity of
• Supports configurable VLAN switching when MAC address lookup should be omitted
• Classification and Priority assignment based on Port Number, MAC Address, Ipv4
• Efficient output Queue frame buffering with shared Frame buffer of 24 Kbyte
• Each port implements four priority queues with configurable weighted round-robin
• Support Ethernet Multicast, Broadcast with flooding control to avoid unnecessary
• Programmable Multicast destination port mask to restrict frame duplication for individual
• Multicast and Broadcast resolution with VLAN domain filtering providing a strict
• IP Snooping with programmable protocol and port number registers
