Hi guys About the option -l (the length of buffer to read or write) says the iperf-documentation the following: ... iperf works by writing an array of len bytes a number of times. Default is 8 KB for TCP, 1470 bytes for UDP. Note for UDP, this is the datagram size and needs to be lowered when using IPv6 adressing .... I believe, on an Ethernet the maximum amount of data in a frame is 1500 bytes, which leaves 1472 bytes for our data, assuming 20 bytes to the IP header and 8 bytes for the UDP header. Why isn't the default size of a UDP datagram in iperf 1472 bytes (instead 1470)? Thank you for the answers.
