Cisco :: Prevent VLAN Change On Port?

I often have to change switch ports to different VLANs. Regardless of whether I find the ports myself or if someone tells me what the ports are, I'll always perform additional verification steps to make sure that the port I'm changing doesn't connect to a switch, a router, a server, or something else that's equally important. But mistakes happen, and I have accidentally changed the wrong port to a different VLAN, thereby disconnecting the end node.

Is there a way to configure a port so that it will not allow you to change its VLAN (or make any configuration changes to it)? I'm imaging a command that when applied to a port would not allow you to make config changes to the port until you remove that command from that port, at which point you'll be able to change its VLAN, shut it, etc. If there isn't such capability, what strategy do you use to minimize the possibility of accidentally changing trunks, routed ports, or important access ports to different VLANs (other than labeling and verify)?
