The only thing those VLAN's have in common are the numbers. But they
do not know anything from each other. The VLAN tag on a VLL is always
only port significant. Means you can have the same VLAN on as many
VLL's as you want and still no traffic is leaking. Useful if you have
different customers with the same VLAN tag.

There is a good description in the config guide, somewhere... :-)

Kind regards
