Features

AI Translation
  • 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
  • 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
  • Two Configurable External MAC Ports
    • Reduced Gigabit Media Independent Interface (RGMII) v2.0
    • Reduced Media Independent Interface (RMII) v1.2 with 50MHz reference clock input/output option
    • Media Independent Interface (MII) in PHY/MAC mode
  • 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
