Create multiple ifcfg files in /etc/sysconfig/network-scripts, e.g. for multiple VLANs on eth0: ifcfg-eth0 ifcfg-eth0.2 ifcfg-eth0.100 The number after the decimal is the VLAN id (default (1), 2 and 100 respectively above). In each file, add VLAN=yes. And don't forget to turn on trunking on the switch to which you're attached. The network startup scripts will then do the right thing.
