Simple question :)

Is it possible to shut off the vty in the Cisco so that it can only be
accessed locally other than through access-lists?  I'm getting the hang
of access-lists (they seem bloody simple except for the inverted masks)
and I couldn't find any reference on the subject (other than using
ACLs).
