Hi. I've configured vlans on CentOS using the vconfig program. If I recall correctly, 802.1q support is already in the CentOS kernel.

Here's a document that looks similar to what I've done in the past to get this working: http://www.linuxjournal.com/article/7268

Just make sure you use 'switchport trunk encapsulation dot1q' on your switch. Let me know if you need any more help with this.

Thank you for your assistance ,I've just read your article but it's only using CENTOS to configure trunk with switch layer 2 , I mean I want to devide VLAN by CENTOS to replace switch (for example I don't have cisco switch).

Ah, so you want your machine to become the switch. We tried something like that once, but it ended up not working out so well. What you can do is bond virtual interfaces to external ones. So, say you have eth0.3002, you can bond this to say eth2 and it'll act like a bridge. The program to do that is called ifenslave. I haven't used it in some time, however.
