mininet 操作命令

2.mininet操作

• 2014/9

1.启动mininet

运行 sudo mn

以下是结果

administrator@ubuntu:~$ sudo mn
*** Creating network
*** Adding controller
*** Adding hosts:
h1 h2 
*** Adding switches:
s1 
*** Adding links:
(h1, s1) (h2, s1) 
*** Configuring hosts
h1 h2 
*** Starting controller
*** Starting 1 switches
s1 
*** Starting CLI:
mininet> 

可见,mininet默认会建立一个两个主机连接着一个交换机的网络

2.常用命令

mininet> 

help   查看帮助
nodes  查看节点
net    查看链路、
dump    各个节点的信息
exit    退出
gterm hostname  虚拟终端 gnome-terminal
xterm hostname 虚拟终端  xterm
h1 ping h2    h1节点对h2节点进行ping操作
Link Up/Down


 禁用s1与h1通路
 
 link s1 h1 down
 
 启用s1和h1通路
 
 link s1 h1 up

3.mininet 运行参数

 举例

 使用pox控制器
 $ ./pox.py forwarding.l2_learning
 $ sudo mn --controller=remote,ip=127.0.0.1,port=6633
 让OF交换机工作为“二层自学习交换”
