WebSpanning Tree Convergence Refer to the Spanning Tree Flash animation to see an example that explains how the Spanning Tree initially converges. The example also explains why a blocked port goes into the forwarding mode because of an excessive loss of BPDUs, resulting in STA failure. WebThe good thing is that spanning-tree solves the link failure automatically but it also means that we have a downtime of 30 seconds. If you want you can tune the forward delay timer to speed up this process down to roughly 14 seconds. SW3 (config)#interface fa0/14 SW3 (config-if)#no shutdown Let’s restore connectivity first.

WebSpanning Tree Protocol (STP) convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state. When layer 2 is converged, Root Switch is elected and Root Ports, Designated Ports and Non-Designated ports in all switches are selected. WebIn an STP converged network, the root port is in the STP forwarding state. Alternate —Alternate ports lead to the root bridge but are not root ports. The alternate ports maintain the STP blocking state. Backup —This is a special case when two or more ports of the same switch are connected together (either directly or through shared media).

WebSpanning Tree Protocol (STP) belongs an Layer 2 protocol that runs to bridges and switches. The specification for STP the IEEE 802.1D.
