Ethernet port N where N = 1 to 2
The total number of frames on the port that experienced carrier loss. Such a frame:
- Was any data or MAC control frame destined for any unicast, broadcast or multicast address
- Was any size
- The carrier sense condition was lost or never asserted when transmitting the frame (the frame is not retransmitted). This is a transmit only statistic. Carrier Sense is a don’t care for received frames. Transmit frames with carrier sense errors are sent until completion and are not aborted.
CRC errors and underrun have no effect upon this statistic.
