If by that you mean 802.1q trunking, then yes.

Seems to be in my experience, but that's only limited so far.

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.
