VLAN Tagging Tutorials?

[paddyhasneeds]

Obviously Google throws up a ton, but does anyone have a tutorial/article on VLAN tagging that explains it in an easy to digest format?

Don't have an issue with the concept of VLANs but tagging is something I need to get my head around and I seem to be struggling a little.

Thanks.

Ok, in a nutshell, lets suppose we have two switches with some ports on VLANs 1,2 and 3.

In order to link the switches we assign one port on each as a trunk port and use this port to interconenct the two switches.

Now, when traffic flows from one switch to another on this 'trunk', the packets will be 'tagged' showing which VLAN they eminate from so that the receiving switch knows which VLAN they should go to.

It's as simple as that.

Thanks very much. The tagging/trunking was what I couldn't get my head around but having read your reply and looked at a few others I think I have it clear in my head now - thanks again.
