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
sudo mininet -c 清理配置信息
Options:
-h, --help show this help message and exit
--switch=SWITCH ivs|lxbr|ovs|ovsk|ovsl|user[,param=value...]
--host=HOST cfs|proc|rt[,param=value...]
--controller=CONTROLLER default|none|nox|ovsc|ref|remote[,param=value...]
--link=LINK default|tc[,param=value...]
--topo=TOPO linear|minimal|reversed|single|torus|tree[,param=value...]
-c, --clean clean and exit
--custom=CUSTOM read custom topo and node params from .pyfile
--test=TEST cli|build|pingall|pingpair|iperf|all|iperfudp|none
-x, --xterms spawn xterms for each node
-i IPBASE, --ipbase=IPBASE base IP address for hosts
--mac automatically set host MACs
--arp set all-pairs ARP entries
-v VERBOSITY, --verbosity=VERBOSITY info|warning|critical|error|debug|output
--innamespace sw and ctrl in namespace?
--listenport=LISTENPORT base port for passive switch listening
--nolistenport don't use passive listening port
--pre=PRE CLI script to run before tests
--post=POST CLI script to run after tests
--pin pin hosts to CPU cores (requires --host cfs or --host rt)
--nat adds a NAT to the topology that connects Mininet to the physical network
--version
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”
