Integrated in MAIN domain: One instance of the 3-port Gigabit Ethernet Switch (CPSW3G) subsystem provides Ethernet packet communication for the device. The CPSW3G subsystem provides the following main features:
- Two external Ethernet ports with selectable RGMII and RMII interfaces and one internal Communications Port Programming Interface (CPPI) port.
- Synchronous 10/100/1000 Mbit operation
- Flexible logical FIFO-based packet buffer structure
- Support of eight priority level Quality Of Service (QOS) - 802.1p
- Support for Audio/Video Bridging (P802.1Qav/D6.0 and 802.1Qaz)
- Ethernet port reset isolation
- Support for IEEE 1588 Clock Synchronization (2008 Annex D, Annex E and Annex F)
- Differentiated Services Code Point (DSCP) Priority Mapping (IPv4 and IPv6)
- IPV4/IPV6 UDP/TCP checksum offload
- Priority Based Flow Control (801.1QBB) and Flow Control (802.3x) Support
- Wire rate switching (802.1d)
- Store and Forward Switching
- Non-Blocking switch fabric
- Support of Time Sensitive Network - IEEE P902.3br/D2.0 Interspersing Express Traffic and IEEE 802.1Qbv/D2.2 Enhancements for Scheduled Traffic
- Address Lookup Engine (ALE) with 512 ALE table entries
- EtherStats and 802.3 Stats Remote Network Monitoring (RMON) statistics gathering (per port statistics)
- Maximum frame size of 2020 bytes
