Ado we start the experiment.
First, add a device.
Because we add a routing device, we want him replaced with a switch device.
Click to change.
Such a switch on the replacement of our success. Only two interfaces, but the two do not go with the interface, which is used to receive with the output. If you want to connect to a PC, then we want to add a job board.
右击点击设置。
添加一个16口的一个设置，点击应用然后确定。
Such a switch interface becomes a lot, and that begins with a 0 separately, we have to link interface beginning with 1.
Next we add two PC then they are connected by a network cable, pay attention to the interface.
Then run our simulation equipment, double-click simulation equipment, to enter the setup interface. Side of the system settings interface is similar to the Windows DOS window, you need to use some of the commands, common commands refer to my previous article. 
First use the configure terminal command to enter global mode, then use the no ip routing command to disable the routing function, so that our switch is set to go, then we give two analog PC are accompanied by a same segment of the IP address.
PC1's IP is 192.168.8.8 I configured the subnet mask is 255.255.255.0
PC2 is 192.168.8.10 subnet mask is 255.255.255.0, use the ping command to check each other after they complete Tonglian.
If you try to address a ping not, the result is not through.
