The Catalyst enterprise LAN switches use the Spanning-Tree Protocol (STP, the IEEE 802.1D bridge protocol) on all Ethernet, Fast Ethernet, Gigabit Ethernet, and Token Ring port-based VLANs.
How Spanning Tree Protocol Works The spanning-tree operations are as follows: STP elects a Root Bridge and both the ports of the Root Bridge are designated ports and are placed in the forwarding state. The non Root Bridge considers one of its ports as a root port with the least administrative cost and the other port considers as a non designated port. Root port placed in the forwarding state

Introducing Spanning Tree Protocol 47 The bottom line is that 802.1w usually converges in less than a second. All Cisco switches running recent software versions make 802.1w the default STP.
The spanning tree algorithm allows to remove logical rings from the network physical topology, by disabling links to transform a mesh topology (graph) into a tree called spanning tree, whose root is one of the bridges called root bridge.
In this case, Spanning Tree Protocol will choose the local port which recieves the BPDU with lowest Spanning Tree Port Priority value from the neighbour switch as the Root Port. Default Spanning Tree Port Priority value value is 128 and you may change the Port Priority value in increments of 16.

The Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network. The basic function of STP is to prevent bridge loops and ensuing broadcast radiation. Spanning tree also allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails, without the danger of bridge loops, or
The main difference between Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) and Spanning Tree Protocol (STP IEEE 802.1D) is that Rapid Spanning Tree Protocol (RSTP) assumes the three Spanning Tree Protocol (STP) ports states Listening, Blocking, and Disabled are same (these states do not forward frames and they do not learn MAC addresses). Hence RSTP places them all into a …
