Regardless, if there is no STP state because there is no STP on a layer 2
port, the SVI will NOT be up!!!
What you say right here is what we mean
"It tracks SVI up/down state based on the STP state of that VLAN. When STP
goes to forwarding on at least one port/VLAN, the SVI comes up"
If there is no L2 VLAN there is NO POINT for an L3!!!!! The switches are
smart enough to know that!!!!!!

The feature you're talking about is called autostate.
It tracks SVI up/down state based on the STP state of that VLAN. When STP
goes to forwarding on at least one port/VLAN, the SVI comes up.
You can change this behavior on the 6000/5000/4000 series w/ Hybrid OS, but
I can't find a way to disable autostate on the 3550.
Anyone know a hidden command?
