2. 사용 방법
|
옵션 -i : interval 간격 -s : server mode -c [server ip] : client mode -u : UDP -b : bandwith -t : time (client에서 전송
|
- server mode
"-u" 옵션을 사용할 경우 UDP성능측정이고 없을 경우 TCP측정이다.
[root@test-2 ~]# iperf -s -i1
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------- client mode
서버와 동일한 설정으로 하되 -c와 서버 IP를 입력한다.
[root@test-1 ~]# iperf -c 172.10.4.67 -b10000M -i1 -t 30
------------------------------------------------------------
Client connecting to 172.10.4.67, TCP port 5001
