华为交换机S5700解除ip/Mac绑定

华为中有三种模式
用户视图<2F-A>：基本操作，查看基本信息
系统视图[2F-A]：进阶操作，能看信息也可以配置
接口模式[2F-A-GigabitEthernet0/0/1]：

1. 交换机解除绑定的IP地址提示地址在使用

[2F-A-Vlanif70]undo dhcp server static-bind ip-address 70.70.70.72                           
Error: The IP address is being used by a static-MAC user.

2. 查询配置信息知道70.70.70.0/24网段的DHCP是基于接口地址池

关于华为配置DHCP请查看：https://support.huawei.com/enterprise/zh/doc/EDOC1100212349/6946084b
