The output above clearly shows that you have two new interfaces: eth0.200 and eth0.300.
Once your VLANs have been configured, perform a quick restart of the network service to bring up the interfaces. # cat /etc/sysconfig/network-scripts/ifcfg-eth0.300 The output below shows the configuration that is needed for VLANs 200 and 300: # cat /etc/sysconfig/network-scripts/ifcfg-eth0.200 You already saw the configuration necessary for the untagged (native) VLAN: It’s the same configuration that used above for eth0. Second, use the VLAN=yes directive to configure this subinterface as a VLAN. This practice associates the VLAN with the appropriate parent interface. First, specify the interface name in the form of parentInterface.vlanID. This network configuration looks like any other interface with a few important distinctions. Like most network configurations, you set up VLANs in the appropriate /etc/sysconfig/network-scripts interface configuration file. However, I’ll manually enable it for the sake of demonstration: # lsmod | grep 8021q In practice, this module is automatically loaded if you configure a VLAN subinterface. Network symbols provided by the LibreOffice VRT Network Equipment extension.įirst, ensure that the 802.1Q kernel module is loaded.
Therefore, you need to configure your host to recognize that VLANs are involved here: The second and third VLAN (200 and 300) are carried across the trunk with an 802.1Q tag. The first is VLAN 100, which is carried untagged across the port because it’s the native VLAN. In the topology below, you can see a host (A KVM hypervisor, for example) connected to a switch’s trunk port with three VLANs involved. Next, take a look at a more complex topology. There isn’t any VLAN configuration on the host, but the switch is likely configured to place the host on a particular VLAN. The above configuration is probably familiar to most who have administered a Linux server. # cat /etc/sysconfig/network-scripts/ifcfg-eth0 # ip addr sh eth0Ģ: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

Good job! You learned how to configure NIC( Network Interface Card) bonding in CentOS 7 / RHEL 7.ĭear user, we hope you would enjoy this tutorial NIC teaming in CentOS 7, you can ask questions about this training in the comments section, or to solve other problems in the field of Eldernode training, refer to the Ask page section and raise your problems in it.Network symbols provided by the LibreOffice VRT Network Equipment extension. ~]# ifdown eno1 Device ‘eno1’ successfully disconnected. You can down one interface and check whether you are still able to access the server, to test the fault tolerance To view bond interface settings like bonding mode and slave interface: ~]# cat /proc/net/bonding/bond0 5- Fault tolerance testing To check the bond interface along with its slave interfaces, Use ‘ ifconfig‘ & ‘ ip add‘ command. Here we select ‘ mode=5′ which is used to provide fault tolerance and load balancing.įor ifcfg-eno1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eno1 TYPE=Ethernet BOOTPROTO=none DEVICE=eno1 ONBOOT=yes HWADDR="08:00:26:79:60:b9" MASTER=bond0 SLAVE=yesįor ifcfg-eno2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno2 TYPE=Ethernet BOOTPROTO=none DEVICE=eno2 ONBOOT=yes HWADDR="08:00:26:ed:71:2d" MASTER=bond0 SLAVE=yesīy the following command, you can restart the network service and bring the above changes into the effect. Next, specify the IP address, Netmask & bonding modes. List the bonding module-info: ~]# modinfo bondingįirst, create a bond interface file ( ifcfg-bond0) under the folder “ /etc/sysconfig/network-scripts/” network-scripts]# vi ifcfg-bond0 DEVICE=bond0 TYPE=Bond NAME=bond0 BONDING_MASTER=yes BOOTPROTO=none ONBOOT=yes IPADDR=192.168.10.70 NETMASK=255.255.255.0 GATEWAY=192.168.10.1 BONDING_OPTS="mode=5 miimon=100" we start with two interface cards (enp0s3 & enp0s8) and will form a bond interface (bond0).
