Thanks. We'll let you know when a new response is added.

Not much really happens except you are running it through another port.  Does not make much sense to do something like this, but, nothing bad happens.

INCORRECT – Really BAD things happen. Most HUBS allow this to happen, as they auto-crossover these days, but as they are not switches, they do not run spanning tree, so you create a loop, traffic goes round and round, and your network dies. .

    Bad answer Harisheldon, most HUBS allow this to happen, as they auto-crossover these days, but as they are not switches, they do not run spanning tree, so you create a loop, and your network dies. The OP of this question should really do some work for themselves in researching this answer.
