If by that you mean 802.1q trunking, then yes.
ls it reliable?
Seems to be in my experience, but that's only limited so far.
how can I do it?
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.
Are the details documented somewhere? Is vlan 1 always native (untagged) or can you specify that? I remember having some problem with Intel NICs on windows not liking native packets at all if any were tagged but I don't know if that was a hardware or software issue.
