华为5700 dhcp配置实例

同网段内配置基于接口地址池的DHCP服务器示例组网需求如图1所示，某企业有两个处于同一网络内的办公室，为了节省资源，两个办公室内的主机由SwitchA作为DHCP服务器统一分配IP地址。办公室1所属的网段为/24，主机都加入VLAN10，办公室1使用DNS服务和NetBIOS服务，地址租期30天；办公室2所属的网段为/24，主机都加入VLAN11，办公室2不使用DNS服务和NetBIOS服务，地址租期20天。配置思路基于VLANIF接口地址池的DHCP服务器的配置思路如下：1.在SwitchA上创建两个接口地址池并配置地址池相关属性，实现DHCP服务器可以根据不同需求，从不同的接口地址池中选择合适的IP地址及其配置参数分配给办公室主机。2.在SwitchA上配置VLANIF接口基于接口地址池的地址分配方式，实现DHCP服务器从基于接口的地址池中选择IP地址分配给办公室主机。操作步骤1.使能DHCP服务2. system-view3.
