Hi.

If the config has disappeared from the runnning config, then it is actually deleted. What you see is that some info in the IDB (Interface Descriptor Block, as far as I remember) is still present, but it won't interfere with your network as such.

Only if you again start to configure a fa1/0/4.22 interface you have the possibility (risk) of having some old config that will be active again. If you want to avoid that, only a reload will fully remove a deleted interface.
