华为交换机如何批量清除接口配置信息
解决方案：
1.单接口下清除
系统试图下
[Huawei]clear configuration interface GigabitEthernet 0/0/1（清除0/0/1口配置）
Warning: All configurations of the interface will be cleared, and its state will
be shutdown. Continue? [Y/N] :y
[Huawei]int GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]dis this
shutdown
因清除接口下的配置后为shuadown (关闭)状态
[Huawei-GigabitEthernet0/0/1]undo shutdown 开启接口
#
return
接口下
[HW1730s-GigabitEthernet0/0/49]clear configuration this
Warning: All configurations of the interface GigabitEthernet0/0/49 will be cleared, and its state will be shutdown. Continue? [Y/N] :y.
Info: Total 2 command(s) executed, 2 successful, 0 failed.

2.多接口统一清除
先建端口组，将端口批量加入端口组
[HUAWE]port-group 1
[HUAWEI-port-group-1]group-member GigabitEthernet0/0/3 to G0/0/6
在端口组下undo现有配置即可
[HUAWEI-port-group-1]undo p l
[HUAWEI-port-group-1]undo p d
