Don't have that particular information but here's a good link showing
that
properly configured vlan's on Cisco switches are indeed secure.

Hi,

A few months ago somebody from group had posted a link to "Don't use
VLANs
as
security measures". The web site that had this article described it with
all
the details on how VLANs can be leaked and intruders can hack in to your
internal network.

If anybody have that link can you please e-mail it to me? I saved my
previous
copy very well so can't find it any more :-)

Thanks,
Sam Munzani
