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
[Huawei-Ethernet0/0/2]shutdown
[Huawei-Ethernet0/0/3]shutdown
[Huawei-Ethernet0/0/4]shutdown
[Huawei-Ethernet0/0/5]shutdown
[Huawei-Ethernet0/0/6]shutdown
[Huawei-Ethernet0/0/7]shutdown
[Huawei-Ethernet0/0/8]shutdown
[Huawei-Ethernet0/0/9]shutdown
[Huawei-Ethernet0/0/10]shutdown
[Huawei-Ethernet0/0/11]shutdown
[Huawei-Ethernet0/0/12]shutdown
[Huawei-Ethernet0/0/13]shutdown
[Huawei-Ethernet0/0/14]shutdown
[Huawei-Ethernet0/0/15]shutdown
[Huawei-Ethernet0/0/16]shutdown
[Huawei-Ethernet0/0/17]shutdown
[Huawei-Ethernet0/0/18]shutdown
[Huawei-Ethernet0/0/19]shutdown
[Huawei-Ethernet0/0/20]shutdown
[Huawei-port-group-1]
