可以按一下步骤进行：

首先登录进交换机

进入系统视图,命令为：system-view

进入以太网端口视图：

命令格式： interface interface-type interface-number

参考一下例子：

system-view

[Switch] interface fastethernet0/1

Switch[fastethernet0/1]在此情况下，可对此端口进行配置，显示。

如:portaccess vlan 100; fastethernet0/1是vlan100的一个端口

1、设置端口组

2、然把端口加入到端口组

3、最后在端口组下设置关闭所有端口

配置示例

[Huawei]port-group 1

[Huawei-port-group-1]group-member Ethernet 0/0/1 to Ethernet 0/0/20

[Huawei-port-group-1]shutdown

[Huawei-Ethernet0/0/1]shutdown
