How to Troubleshoot Spanning-Tree Protocol

In most networks, the best Spanning-Tree Protocol topology is determined as part of the network blueprint. The Spanning-Tree Protocol is implemented by configuring Spanning-Tree Protocol priority and cost values. Several things could go wrong. You can expect something, but your switches can give you something different. Situations also occur when the Spanning-Tree Protocol was not… Read more

Spanning Tree – Root Bridge

Every spanning tree switched network or broadcast domain has a switch designated as the root bridge. It serves as the reference point for all spanning-tree-enabled switches. The spanning tree algorithm determines which redundant paths to block. It is selected as an election process. The figure below illustrates the bridge ID (BID) fields. BID is a
