如何通过stp限制交换机接口

1. 进入接口配置模式：

```

Switch> enable

Switch configure terminal

```

2. 进入指定接口的配置模式：

```

Switch(config) interface interface-type interface-number

```

例如，要进入GigabitEthernet 0/1接口的配置模式：

```

Switch(config) interface GigabitEthernet 0/1

```

3. 配置接口类型：

根据需要配置接口类型，如：

`shutdown`：关闭接口。

`desirable`：设置接口为转发状态。

`not-forwarding`：设置接口为阻塞状态，不转发数据包。

`block`：设置接口为阻塞状态，不转发数据包，但允许BPDU通过。

例如，要将接口设置为阻塞状态：

```
