The vlan interfaces were successfully created on the previous step. TX packets:0 errors:0 dropped:0 overruns:0 carrier:0Įth1.12 Link encap:Ethernet HWaddr 00:30:48:BF:4E:BDģ. RX packets:0 errors:0 dropped:0 overruns:0 frame:0 ifconfig -aĮth1.11 Link encap:Ethernet HWaddr 00:30:48:BF:4E:BD You also see the vlan interfaces by typing ‘ifconfig -a’ command.
Linux will consider these as another network devices so you can configure and assign IP address like other. These commands above will create devices eth1.11 and eth1.12 to your system. To create a vlan interface, use ‘vconfig add’ command as below: vconfig add eth1 11 We will create interface vlan 11 and vlan 12 on this eth1 interface. We have to bring the interface up without IP address assigned to it before we can use it. We will use eth1 interface in the Linux box. If you see something similar like above, the 8021q has been successfully loaded. Make sure the module was successfully loaded by running the ‘lsmod’ again lsmod |grep 802 If there is nothing shown by lsmod command, it means the module has not been loaded yet. You can check whether it is already loaded or not by using ‘lsmod’ command. This tutorial is based-on network diagram below:īy default the 802.1q module is not loaded so we firstly have to load it. 2 PC/Laptop running Windows/Linux/BSD/MacOSX It should be applicable on other Linux distros such as Slackware, Ubuntu, Fedora, Debian, etc.ģ. Linux installed on a PC with one or more NICs (Network Interface Card).
