I have an external DSL link on a ground floor of my building that needs to be sent up to the second floor. Now im sure it would be easy to just run a cable however thats not an option. However, i do have cisco 3750 switches on each floor and they are all tied in floor by floor.
My question is how do I create a vlan and trunk this DSL link through my switches to the second floor without it broadcasting through my network other than on a port specified on my second floor?
EDIT:
I tried to user Panther Modern's answer, but I still can't get it to work.
Here is what my port configuration looks like floor to floor for what I am trying to do. Please let me know if you see anything that could be stopping the traffic flow.
