What do you mean "Cannot act as a bridge"?

A switch uses MAC addresses for ascertaining where to forward

Yup. That's bridging, defined in 802.1d

The newbies don't remember bridges. You're going to be here for a while explaining it if you're in the mood to teach.

Some of us remember when you needed them to break up a too-busy LAN into segments...

Non-managed dumb switches are just multiport bridges... you're correct.
