Document No.: AX88655AB / V0.8 / June 11, 2003
Features
5-port Gigabit Ethernet switch integrating MACs, packet buffer memory and switching engine with RGMII/GMII/MII interface RGMII support REV 1.3 with 3.3V IO Full Duplex 1000 Mbit/s. Full and Half Duplex 10/100 Mbit/s Supports auto-sensing or manual selection for speed and duplex capability with an embedded MPU Store-and-forward operation support Performs full wire-speed switching with Head of Line (HOL) blocking prevention Supports up to 8 Port-based VLAN Groups Supports broadcast storm filtering. Quality-of-Service provisioning on 802.1P tag and port-pairs with two priority queues By-port Egress/Ingress bandwidth (rate) control Embedded 128K Byte SRAM for packet buffer Supports packet length up to 1522 bytes Supports 9K/12K byte JUBMO packet Integrated two-way Address-Lookup engine and table for 4K MAC addresses
Programmable aging mechanism for the two-way 4K MAC addresses table Two hashing schemes: direct and XOR mode. Support ingress port security mode, incoming packets with unknown source MAC address could be dropped Egress/Ingress Port Mirroring for Sniffer function. Flow control - Full-duplex IEEE 802.3x flow control - Half-duplex back pressure flow control - Optional smart flow control for mix-speed connection Supports port-based trunking for high-bandwidth links Provides 5 GPIO port……
