I'm studing for the BCMSN exam.
I have a doubt about when does a port is assigned the roll of Designated Port. I know the theory about it, but I would like an explanation in somebody's own words to have a better understanding.
I hope this explanation will help youâ¦.here is the process that spanning tree uses in order to prevent loops. First, a root bridge is selected based upon the Bridge ID value. Next, one root port is selected on each non-root bridge. This selection is based upon the best bandwidth path back to the root. Next, one designated port is selected on each link. Again, bandwidth is the first value analyzed to make the decision. All remaining ports are considered non-designated and are placed in the blocking state.
I look forward to any follow up questions that you might have!
