Switching loops

[samith_me]

Two deferent switches are connected to each other by using two cables. By default spanning tree running and blocked by one path and other path is using to send data. Now I need to block the working path and use to transfer data other path (the blocked path). How to do that. Please help

 You may need to change port priority on the root switch.

Thanks,

You unplug the cable or shut down the port on the working path.

Spanning tree will reconverge and your previously 'blocked' path will transition into the forwarding state.
