Support for DTE or DCE operation
Half- and full-duplex flow control per IEEE 802.3
Jumbo frame lengths up to 10KB for GbE
64-byte minimum frame size
Ethernet management interface (MDIO)
Supports applicable RMON (RFC2819) counters
Promiscuous and broadcast discard modes
OAM frames can be intercepted, processed by host software, and responses inserted
4K address and VLAN ID lookup table for learning and filtering
Programmable aging between one to 300 seconds in one-second intervals
Ingress classification according to Ethernet COS
Programmable class map to four queues for each Ethernet port
Ingress classification by PCP or DSCP
Programmable class mapping to four queues
Programmable bandwidth profiling at either the port level or per-class level
Programmable bandwidth profiling for multicast and broadcast flows
Policing with programmable CIR/CBS
Nonconforming Ethernet frames discarded according to the configured BW profile
Programmable scheduler for Ethernet flows toward PDH port(s):
Control frames, except PAUSE and OAM, are forwarded without processing
PAUSE and OAM frames can be programmed to be intercepted, discarded or forwarded
Programmable carrier VLAN tag insertion
SDRAM Interface
Interface for up to 256Mb DDR SDRAM (JEDEC JESD79D compliant)
Compatible with DDR266+
16-bit-wide data bus with dual edge transfers and auto refresh timing
