Display STP (Spanning Tree Protocol) Brief is a command used in network devices, particularly those running the Spanning Tree Protocol, to show or summarize the configuration and state of the Spanning Tree Protocol. This command provides essential information about the Spanning Tree instance, such as:
1. **Bridge ID**: It displays the unique identifier for each bridge participating in the network's spanning tree.
2. **Root Bridge**: Information about the designated root bridge in the network, including its ID and priority.
3. **Topology Status**: The current state of the network topology, whether it's in forwarding, listening, learning, or blocking mode.
4. **Ports**: Details about each port (like its status, role, and type), including designated (forwarding), root, alternate, or blocked ports.
5. **Bridge Priority**: The numerical value that determines the priority of each bridge in the network.
6. **Path Cost**: A metric used to calculate the best path between switches; lower path costs indicate a shorter path.
To get a clear understanding, you can run the "display stp brief" or a similar command in your specific networking device's CLI (Command Line Interface), which will provide a concise summary of the STP configuration and its operational status.
