EMAC Port Registers
The total number of oversized frames received on the EMAC. An oversized frame is defined as having all
of the following:
•
Was any data or MAC control frame that matched a unicast, broadcast, or multicast address, or
matched due to promiscuous mode
•
Was greater than RXMAXLEN in bytes
•
Had no CRC error, alignment error, or code error
See
for definitions of alignment, code/CRC errors. Overruns have no effect on this statistic.
The total number of jabber frames received on the EMAC. A jabber frame is defined as having all of the
following:
•
Was any data or MAC control frame that matched a unicast, broadcast, or multicast address, or
matched due to promiscuous mode
•
Was greater than RXMAXLEN bytes long
•
Had a CRC error, alignment error, or code error
See
for definitions of alignment, code, and CRC errors. Overruns have no effect on this
statistic.
The total number of undersized frames received on the EMAC. An undersized frame is defined as having
all of the following:
•
Was any data frame that matched a unicast, broadcast, or multicast address, or matched due to
promiscuous mode
•
Was less than 64 bytes long
•
Had no CRC error, alignment error, or code error
See
for definitions of alignment, code, and CRC errors. Overruns have no effect on this
statistic.
The total number of frame fragments received on the EMAC. A frame fragment is defined as having all of
the following:
•
Any data frame (address matching does not matter)
•
Was less than 64 bytes long
•
Had a CRC error, alignment error, or code error
•
Was not the result of a collision caused by half duplex, collision based flow control
See
for definitions of alignment, code, and CRC errors. Overruns have no effect on this
statistic.
