Guys,

GREAT EXPLANATION !! Worth much more than the one in DOCCD... I read that one
several times but did not get it... Now, I feel better about the native vlan.

I have a question though: is it possible to configure different native VLANs on
the ends of a trunk between Cisco switches ?

As far as I could see in the lab, as soon as I configure one end, the trunk is
brought down and an error message pops up, something like: "native VLAN
mismatch... bringing down the trunk".
After I configure the SAME native vlan on the other end of the trunk, this
comes up. As far as I know, this is transmitted via CDP.

I guess scenario 3 does not work with Cisco switches. Maybe between Cisco and
non-Cisco or between non-Ciscos...

TIA, Mihai
