Ado start test, the test VPCS Virtual PC like before GNS3 above switch settings, it is mainly VPCS replaced VMware virtual machine on top of the Windows system.
Adding an interface device in accordance with the steps.
Using the command config terminal (enter the global mode) with no ip routing (turn off the routing function), then switch setting is complete.
Enter the following settings VM virtual machine, click the first Windows virtual machine to bind the first network card.
If the card is not enough under the circumstances, click Edit virtual machine under Virtual Network Editor to add it. Enter the Virtual Network Editor interface, click Change Settings and then click Add a network, add a second network card.
Then let our Windows virtual machine a second binding a second network card, and an IP address on the same subnet to which the two Windows virtual machine.
】
I first configuration is IP192.168.8.8 subnet mask 255.255.255.0.
Then I gave a second Windows virtual machine configuration is 192.168.8.10 subnet mask of 255.255.255.0, then let them in on GNS3 software connected with two switches.
Add VPCS but not here add two Host host connection when the attention of the interface.
Using the first virtual NIC 1 (VMnet1), using a second stage (VMnet2) is connected to the switch.
Then I VM virtual machine on top with a second host to try to connect the first host, see if you can communicate.
Successful, then use a Wireshark packet capture software, to see if I can successfully get two virtual machines send data to each other, right-click the network cable running Wireshark.
OK, we have been successful with the VM virtual machine simulation in GNS3 achieve the above function of a switch.
