Web5 Sep 2012 · STP helps find redundant links and place one in a blocking state. Without STP, all switches “flood” any frames they receive with an unknown destination media access control (MAC) address. The switches will forward the frame to all interfaces, introducing duplicate frames and leading to a “loop” in which all switches continually forward all frames. WebThe set spantree backbonefast enable command for CatOS or the spanning-tree backbonefast command for Cisco IOS Software can increase the STP convergence time of the switch in the event of an indirect link failure.
