I tried to do some more research on this and couldn't get a good answer.
Does anyone know exactly in which cases the router reports the interface
up, down even if there is no cable attached? Looking at show interface
ethernet,
Router reports up, down with no cable for AUI.
How about RJ45?
How about MII?
GMII?
Others?
Thanks
