6.2.5 Transmit MAC Statistics
6.2.5.1 Counters:
The Transmit MAC provides statistics and performance monitoring, to facilitate remote
network monitoring (RMON) per Groups 1, 2, 3, and 9, in addition to supplementary statistics.
The MAC records the following statistics using counters that are programmable as either
clear on read saturating counters or rollover counters (Register 0x0030 Bit 0).
• Total number of bytes transmitted. This counter can be programed to exclude byte
• Total number of frames transmitted. This includes all frames, broadcast and multicast
• Count of Multicast frames transmitted (32 bit)
• Count of Broadcast frames transmitted (32 bit)
• Count of PAUSE Control frames transmitted (32 bit)
• Count of VLAN tagged frames transmitted (32 bit)
• Count of frames transmitted with a valid FCS and total byte count is between 1519 and
• Count of frames transmitted with a valid FCS and length less than 64 bytes (32 bit)
• Count of deferred frames transmitted (32 bit)
• Count of excessive deferred frames transmitted (32 bit)
• Count of single collision frames (32 bit)
• Count of multiple collision frames (32 bit)
• Count of late collision frames (32 bit)
• Count of excessive collision frames (32 bit)
• Count of frames transmitted with an invalid FCS and length less than 64 bytes (32 bit)
• Count of frames transmitted with an invalid FCS and total byte count is between 1519
• Count of frames transmitted with an invalid FCS and total byte count is between 64 and
• Count of dropped frames due to lack of system resources (32 bit)
• Count of aborted frames under command of the Egress FIFO logic (32 bit)
• Six sets of counts for frame sizes that fall in a certain range. The ranges are 64 bytes, 65
• Count of PAUSE frames originated via SPI-3 interface that are discarded (32 bit)
counts from errored frames (40 bit)
