Vlan Trunking on a host

I have been looking for a way to test our networks without having to drag a switch along with me to every site.

I found a page that suggests i can vlan tag packets coming out of my laptop. But I can't find the tool they say I need.

The page is:
www.lanarchitect.net/Articles/VLANTrunking/Implementation/

It mentions a PROSet tool from intel that they seem to no longer make or distibute. Even if I could find it I don't have an intel card in my laptop.

Can anyone else help with this?

Thx.

This is a very common capability. Essentially, you turn your connection into an 802.1Q trunk. However, I would strongly recommend against configuring access ports on a switch to any mode other than access (switchport mode access). If you can establish a trunk with a port, so can the bad guys.

This is only for testing and the like... We never leave ports open or up if we don['t have to.

Any word on how to do this??? I'm still running into a wall.

A few of my linux buddies are telling me most linux distro's do this natively... I tend to believe them, but nobody knows exactly how to do it.

Anyone know what I should be looking at?
