To add a little more:
Sent, time, _node_, MAC trace, no-error, packet#, type, bytes, [(in hex) 
duration field (0 µs), receiver address, transmitter address and 
ether-type], -------, [(in decimal) IP source address:source port (255), 
IP destination address (-1):destination port (255), IP time-to-live (32) 
and next hop (0)]
