File README.SuSE of Package vlan
Configuring VLAN interfaces on SuSE Linux VLAN interface configuration is supported via the normal ifup/ifdown scripts used for all other network interfaces as well. To create a VLAN interface, you need to create a file named ifcfg-vlanNNN in the /etc/sysconfig/network directory, where NNN is the VLAN ID. The file should contain something like this: ETHERDEVICE="eth0" IPADDR=10.11.1.1 NETMASK=255.255.255.0 NETWORK=10.11.1.0 BROADCAST=10.11.1.255 STARTMODE=onboot The ETHERDEVICE variable specifies to which ethernet interface the VLAN interface should be attached. Also refer to `man ifcfg-vlan`. All the other variables are standard for configuring an IP interface (STARTMODE defines whether the interface is automatically brought up at system boot time - this is usually of concern for hotplugging devices, or interfaces that need to be brought up manually. Setting it to onboot should be the right thing for VLAN interfaces).
