Technical Specifications

Product Introduction

Features

• Switch Management Capabilities
• 10/100/1000Mbps Ethernet switch basic functions: frame buffer management, address look-up table, queue management, MIB counters
• Non-blocking store-and-forward switch fabric assures fast packet delivery by utilizing 4096 entry forwarding table with 256kByte frame buffer
• Jumbo packet support up to 9000 bytes
• Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port
• MIB counters for fully-compliant statistics gathering 34 counters per port
• Tail tagging mode (one byte added before FCS) support at host port to inform the processor which ingress port receives the packet and its priority
• Loopback modes for remote failure diagnostics
• Rapid spanning tree protocol (RSTP) support for topology management and ring/linear recovery
• Multiple spanning tree protocol (MSTP) support
• One Ext. MAC Port with GMII/RGMII/MII/RMII - RGMII v2.0, RMII v1.2 with 50MHz reference clock input/output option, MII in PHY/MAC mode Five Integrated PHY Ports - 1000BASE-T/100BASE-TX/10BASE-Te IEEE 802.3
• Fast Link-up option significantly reduces link-up time
• Auto-negotiation and Auto-MDI/MDI-X support
• On-chip termination resistors and internal biasing for differential pairs to reduce power
• LinkMD cable diagnostic capabilities for determining cable opens, shorts, and length
• Advanced Switch Capabilities
• IEEE 802.1Q VLAN support for 128 active VLAN groups and the full range of 4096 VLAN IDs
• IEEE 802.1p/Q tag insertion/removal on per port basis
• VLAN ID on per port or VLAN basis
• IEEE 802.3x full-duplex flow control and half-duplex back pressure collision control
• IEEE 802.1X access control (Port-based and MAC address based)
• IGMP v1/v2/v3 snooping for multicast packet filtering
• IPv6 multicast listener discovery (MLD) snooping
• IPv4/IPv6 QoS support, QoS/CoS packet prioritization
• 802.1p QoS packet classification with 4 priority queues
• Programmable rate limiting at ingress/egress ports
• Broadcast storm protection
• Four priority queues with dynamic packet mapping for IEEE 802.1p, IPv4 DIFFSERV, IPv6 Traffic Class
• MAC filtering function to filter or forward unknown unicast, multicast and VLAN packets
• Self-address filtering for implementing ring topologies
• Comprehensive Configuration Registers Access
• High-speed 4-wire SPI (up to 50MHz), I2C interfaces provide access to all internal registers
• MII Management (MIIM, MDC/MDIO 2-wire) Interface provides access to all PHY registers
• In-band management via any of the data ports
• I/O pin strapping facility to set certain register bits from I/O pins at reset time
• On-the-fly configurable control registers
• Power Management
• Energy detect power-down mode on cable disconnect
• Dynamic clock tree control
• Unused ports can be individually powered down
• Full-chip software power-down
• Wake-on-LAN (WoL) standby power mode with PME interrupt output for system wake upon triggered events
