The 9-port Gigabit Ethernet Switch (CPSW9G) subsystem provides Ethernet packet
communication for the device, and has the following main features:
- Eight Ethernet ports with selectable SGMII, XFI, QSGMII and USXGMII
interfaces and an internal Communications Port Programming Interface (CPPI)
port
- Synchronous 10/100/1000 Mbit operation
- Flexible logical FIFO-based packet buffer structure
- Eight priority level Quality Of Service (QOS) support (802.1p)
- Support for Audio/Video Bridging (P802.1Qav/D6.0)
- Support for IEEE 1588 Clock Synchronization (2008 Annex D, Annex E and Annex
F)
- Ethernet port reset isolation
- DSCP Priority Mapping (IPv4 and IPv6)
- IPV4/IPV6 UDP/TCP checksum offload
- Energy Efficient Ethernet (EEE) support (802.3az)
- Priority-Based Flow Control (802.1QBB) and Flow Control (802.3x)
Support
- Wire rate switching (802.1d)
- Non-Blocking switch fabric
- Time Sensitive Network Support
- Address Lookup Engine (ALE)
- EtherStats and 802.3Stats Remote Network Monitoring (RMON) statistics
gathering (per port statistics)
- CPSGMII Loopback Modes (transmit to receive)
- Maximum frame size of 2020 bytes
- Host port CPPI Streaming Packet Interface (CPPI_GCLK)
