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.
