Dec 05, 2017 · The primary function of the spanning-tree algorithm (STA) is to cut loops that redundant links create in bridge networks. The STP operates at Layer 2 of the Open System Interconnection (OSI) model. By means of bridge protocol data units (BPDUs) that exchange between bridges, the STP elects the ports that eventually forward or block traffic.

Dear Support, I'm implementing HSRP on core switch in my network, but spanning tree always block one port on the layer 2 switch. my question is how to make Spanning tree don't block port on layer 2 switch or its mean that we can use block port for forwarding port. Pls help find network diagram in at...

Spanning Tree Root Guard is used to prevent the root of a Spanning Tree instance from changing unexpectedly. The priority of a Bridge ID can be set to zero but another Bridge ID with a lower mac address could also set its priority to zero and take over root.
