11.2.7. Setting Up 802.1Q VLAN Tagging
11.2.7. Setting Up 802.1Q VLAN Tagging If required, start the VLAN 8021q module by issuing the following command as root : No visual output indicates the module was not running and has now been loaded. Note that given a correct configuration file, the VLAN 8021q module will be loaded as required and therefore does not need to be loaded separately. Configure your physical interface in /etc/sysconfig/network-scripts/ifcfg-eth X , where X is a unique number corresponding to a specific interface, as follows: Configure the VLAN interface configuration in /etc/sysconfig/network-scripts . The configuration filename should be the physical interface plus a . character plus the VLAN ID number. For example, if the VLAN ID is 192, and the physical interface is eth0 , then the configuration filename should be ifcfg-eth0.192 : If there is a need to configure a second VLAN, with for example, VLAN ID 193, on the same interface, eth0 , add a new file with the name eth0.193 with the VLAN configuration details. Restart the networking service, in order for the changes to take effect. Issue the following command as root :
~]# modprobe --first-time 8021q DEVICE=ethX TYPE=Ethernet BOOTPROTO=none ONBOOT=yes DEVICE=ethX.192 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.1.1 NETMASK=255.255.255.0 USERCTL=no NETWORK=192.168.1.0 VLAN=yes ~]# service network restart
