This is not correct. A switch can run with stations at both speeds. As a
matter of fact, a 10/100 hub is using a dual port switch (aka bridge) to
seperate the 100Mb hub from the 10Mb hub.

There are unmanaged switches. These cannot be configured at all.

I am not sure I understand what you are trying to describe here.
