EOP Abort
EOP Aborts is an End-of-Packet (EOP) termination that is sent out of the IXF1110 MAC
SPI4-2 to tell the upstream SPI4-2 device that a packet is bad. EOP Abort packets are sent
by the IXF1110 MAC under the following conditions:
EOP Abort packets sent out on the RX SPI4-2 may have the packet size modified. When an
EOP abort packet is received on the TX SPI4-2, the IXF1110 MAC sends the packet out to
the SerDes interface with an invalid CRC and is recorded in the TX statistics as a CRC
error.

• Standard size (64-1518 byte) packets that are greater in size than the setting in
• Jumbo frames that meet the filter conditions set in
• RX FIFO overflows.
• Packets received with /V/ error codes on the SerDes interface that are not dropped due
• Runt Packets (under 64 bytes) received that are not dropped due to the setting in
