cent-os$ firewall-cmd --permanent --zone=public --add-port=19999/udp

cent-os$ firewall-cmd --reload

./perftrace_cli -s server_ip -c 10 -i 10ms -m 1

-c: Specify the number of packets to be sent, default is 10;

-i: Specify the packet sending interval, the default is 1ms;

-m: Specify the measurement mode, the default is 1 (Basic Mode).
