Dude,

What does your show vlan look like?

Sounds like you have inherited some vlans via VTP and
maybe you have a few too many and not necessarily the
ones you want on that switch.

Check it and see.

Yep you said you have 65 active active vlans on the
switch...

And here I thought the max was 64 for some reason.

How many are really needed on that switch?
