Editor to share with you how to configure the virtual switch centos7, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Virtual switch configuration
Inux VLAN configuration (vconfig)
Install vlan (vconfig) and load 8021q module
[root@test0001~] # yum install vconfig
[root@test0001~] # modprobe 8021q
[root@test0001~] # lsmod | grep-I 8021q
Use the linux vconfig command to configure vlan
[root@test0001~] # vconfig add eth0 10
Added VLAN with VID = = 10 to IF -: eth0:-
[root@test0001~] # vconfig add eth0 20
Added VLAN with VID = = 20 to IF -: eth0:-
Create two bridges
Brctl addbr br10
Brctl addbr br20
Ifconfig br10 up
Ifconfig br20 up
Link Bridge and VLAN
Brctl addif br10 eth0.10
Brctl addif br10 eth0.20
Create 4 virtual machines using virt-manager
After starting the virtual machine, the logical network port vnet0,vnet1,vnet2,vnet4 produced by the virtual machine is added to different vlan.
Brctl addif br10 vnet0,vnet1
Brctl addif br20 vnet2,vnet3
Enter 4 virtual machines to configure ip
There are two hosts under the two network segments br10 and br20.
The vnet0 and vnet1 ip under br10 are 192.168.10.30 and 192.168.10.99, respectively.
The vnet2 and vnet3 ip scores under br20 are 192.168.10.40 and 192.168.10.101
Vnet0 and vnet1 can communicate with each other through ping
Vnet2 and vnet3 can communicate with each other through ping
Vnet0 and vnet2 cannot communicate with each other through ping.
Vnet1 and vnet3 cannot communicate with each other through ping.
You want the same configuration on another virtual machine with kvm, but you can modify the ip.
The two physical machines are then connected to the interface of the real switch.
The switch is configured as follows:
1. Install the driver first
D:\ Dibit\ Company\ Huawei S5700S-28P-LI-AC\ driver\ Huawei S5700 series switch Switch-MiniUSB-driver.002 console software\ TI_WDF_USBUART_SINGLE_DRIVER_V6.7.2.0_WHQL. If the installation is successful, you can see a TUSB3410 Device (COM3) under the ports (COM and LPT) in the device Manager of windows
two。 Start HyperTerminal (nok)
D:\ Software\ Windows\ xpzhongduan\ HyperTerminal (ok)
File-New connection
The parameters are set as follows
Serial port: COM3
Baud rate: 9600
Data bits: 8bits
Check bit: None
Stop bit: 1 bit
Flow control: None
Transmit Delay (char): 0
Transmit Delay (line): 0
3. Press enter and enter the password cisco123
4. Configure switch port
Configure Port 3
System-view
Int g0/0/3
Port link-type trunk
Port trunk allow-pass vlan all
Configure Port 4
System-view
Int g0/0/4
Port link-type trunk
Port trunk allow-pass vlan all
5. Create as many vlan as you can. Here is to create vlan10 and vlan20.
[Quidway] vlan 10
[Quidway-Vlan10] quit
[Quidway] vlan 20
[Quidway-Vlan20] quit
