Technical Specifications

• Communication Interfaces
  • Integrated 10M/100M/1000M MACs for 10/100 Mbps and 1 Gbps PHY interface rates to use with any PHY interface type (e.g. MII, RMII, GMII, RGMII) depending on application
  • Compatible with SGMII (Serial Gigabit Media Independent Interface) or QSGMII (Quad Serial Gigabit Media Independent Interface) PHY interfaces throughout an internal GMII based connection to AMD LogiCORE™ SGMII IP core and LogiCORE™ QSGMII IP core respectively
  • 10/100/1000 Mbps AXI-Stream interface with a data width of 8 bits @ 125 MHz
  • Half-duplex support in 10/100Mbps PHY interface rates.
• Traffic Management
  • Integrated Ethernet switch fabric supporting up to 32 ports (number limited by the available resources on the device)
  • HoLB (Head of Line Blocking) free switch fabric
  • Shared Dynamic and Static Filtering Database. Implements hardware MAC address learning/ageing and look-up for up-to 9K absolute MAC addresses (synthesis scalable) at wire speed
  • Independent VLAN Learning support for MAC address learning
  • Searchable MAC addresses (and associated information) contained in the Filtering Database
  • Programmable Frame Forwarding port mask to restrict frame forwarding towards port(s)
  • Programmable Ethertype based Frame Forwarding to restrict frame forwarding towards port(s)
  • Static Multicast frame filtering
  • IGMP v1/v2 Snooping1 (IPv4) support for multicast frame filtering
  • Standard Frame size support (1518) or Jumbo frames up to 9 kByte (depends on memory availability)
• Quality of Service
  • Up to 8 priority queues per port (synthesis option)
  • Priority classification based on Ingress Port, PCP bits (802.1p), DSCP TOS bits of the IP packets (IPv4 TOS/IPv6 COS) and Ethertype
  • Programmable remapping from PCP or DSCP fields to internal priority queues on a per-port basis
  • Programmable Priority Regeneration on a per-port basis
  • Egress traffic prioritization based on Strict priority or Weighted Round Robin (WRR) scheduling algorithm
  • IEEE 802.1Q tag-based and Port-based VLANs. VLAN manipulation functions on reception (VLAN insertion) and transmission (VLAN removal/overwrite)
  • MAC Level Ingress Frame Filtering based of Destination MAC address and/or Ethertype on per port basis
  • Token Bucket based Ingress Throughput Rate Limiting on per port basis
  • MAC Level Ingress Frame Rate Limiting on per port basis
  • Credit Based Shaper (CBS) egress throughput rate limiting on per port basis
  • Egress Frame Rate Limiting on per port basis
  • Broadcast/Multicast storm protection
• Time Synchronization
  • 1588 (PTPv2): IEEE1588 Transparent Clock (TC) functionality (End-to-End or Peer-to-peer) at layer-2 and layer-3 (IPv4)
• Network Management & Monitoring
  • IEEE 802.1D Spanning-Tree Protocol (STP) to prevent loops from being formed when switches or bridges are interconnected via multiple paths
  • IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of spanning tree
  • IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) provides link availability in multiple VLAN environments by allowing multiple spanning trees
  • Multisession port mirroring capabilities. Ingress and egress mirroring functions to allow copying of frames to a mirror port. Option for mirroring only filtered frames that match a specific data pattern
  • User/network port-level security via IEEE802.1X authentication and MAC-based filtering
  • Host access control for only frames specified by the user (destination MAC and/or Ethertype based)
  • Per port MAC and switch statistics for managing and debugging purposes
  • Wide range of management interfaces to access control and statistics registers (selectable at synthesis time)
  • I2C master interface for external device configuration (i.e. an EEPROM memory with non-volatile configuration)
• Others
  • Distributed Switch Architecture (DSA) frame tagging to merge application specific messages to management port and to distribute application specific messages to a specific port
  • Exclusive forwarding of known protocol specific frames or custom frames to/from management port
