As we know, RSTP merges "disabled", "blocking", "listening" states of STP into one "discarding" state. However, when a port is linked down, let's say no physical link on the port, is there still a state inside it? If it has, is it in "disabled" state or "discarding" state?
Because in some switch's configuration page, I can only see ports in "disabled" state when they are linked down, so I'm confused with its state.
