SpletThe root switch is the logical center of the STP topology in a switched network. Redundant paths to the root are put in STP blocking mode. BPDUs contain information about the sending switch and its ports. The information includes switch and port MAC addresses, switch priority, port priority, and path cost. The STP uses this information to elect ... SpletIn the absence of STP priorities, or if all of the switches are the same priority, the switch with the lowest MAC will usually take over as root. Starting at the edge of your network make sure all your switch priorities are lower than the root. Also check to make sure you are running the same STP on all the switches.
