Trace: • vlan

Configure vlan on CentOS 5

  • first install vconfig 
    yum -y install vconfig
  • check if module loaded 
    lsmod | grep 8021q

    If not loaded try to load with 

    modprobe 8021q

    If you get a error message, than try a other kernel with vlan support

  • copy /etc/sysconfig/network-scripts/ifcfg-eth0 to /etc/sysconfig/network-scripts/ifcfg-eth0.<vlan>
  • add .<vlan> to DEVICE line
  • add vlan=yes
  • Example: 
    DEVICE=eth0.201
BOOTPROTO=none
BROADCAST=172.16.201.255
IPADDR=172.16.201.13
NETMASK=255.255.255.0
NETWORK=172.16.201.0
ONBOOT=yes
