WebThe root port (switch) on the bridge is the port with the shortest STP cost from the switch to the root bridge. It connects directly to the single root bridge and has the shortest path to the root bridge. When many connections connect to the root bridge, a port cost is determined by analyzing the bandwidth of each link. Designated port how to hold physical gold in a sep ira
