I suggest you read up on the 802.1q standard to learn more about how VLANs work and how they are best used in your configuration. http://standards.ieee.org/getieee802/802.1.html Scroll down a bit and you'll see IEEE 802.1Q, 2003 Edition. 1q also covers priority, but start with the VLAN stuff. //Peter
