Bandwidth/Loss test
Runs a continual stream (--time 0) of UDP datagrams of $BANDWIDTH and reports on the connection every $INTERVAL seconds.
$INTERVAL=5
$BANDWIDTH=2M
# client
iperf --client $SERVER_IP --udp --interval $INTERVAL --time 0 --bandwidth $BANDWIDTH --enhancedreports
# server
iperf --server --udp --interval $INTERVAL
Sample output:
# client
