Hi George, Did you actually modify the VLAN database after hitting that?
Remember that the VLANs won't propagate unless there's a change (or on the summary advertisement interval has passed). I've seen this same thing when setting the password on all switches and not following it up by making a change to trigger a summary advertisement. I assumed it was because something hashed differently upon the password application and didn't match back up until an advertisement had been propagated but I'd love to know more about it.
