# show spanning-tree bridge

## **Command Name**

show spanning-tree bridge

## **Synopsis**

This **show spanning-tree bridge** command displays various information about the Spanning Tree Protocol (STP) bridge configuration and status on a network switch.

## **Description**

The show spanning-tree bridge command is used to view details of the STP bridge on a switch. It provides valuable information such as bridge address, forwarding time, hello time, bridge identifier, maximum age, STP protocol type, bridge priority, and detailed STP information. This command is crucial for network administrators to monitor and manage STP configurations, ensuring efficient network performance and stability.

## **Syntax**

<mark style="color:blue;">**`show spanning-tree bridge [{ address | forward-time | hello-time | id | max-age | protocol | priority | detail }]`**</mark>

## **Parameters**

* **`address`**: Displays the MAC address of the bridge.
* **`forward-time`**: Shows the bridge's forward delay time.
* **`hello-time`**: Provides the bridge's hello time setting.
* **`id`**: Displays the bridge identifier.
* **`max-age`**: Shows the maximum age setting of the bridge.
* **`protocol`**: Indicates the STP protocol version the bridge is using.
