【实验】基于接口和全局DHCP
【华为基于接口下 DHCP】
[ar2]dhcp enable //全局下启用DHCP功能
[ar2]int gi 0/0/0
[ar2-GigabitEthernet0/0/0]dhcp select interface//在接口下启用DHCP分配的IP就是接口的子网
【华为基于svi下的DHCP】
dhcp enable --- 全局使能DHCP 功能
interface Vlanif10
ip address 10.1.1.254 255.255.255.0
dhcp select interface --- 基于接口的DHCP
dhcp server excluded-ip-address 10.1.1.100 10.1.1.252 ---被排除的地址，该地址可用于重要设备 网关会自动排除 一般不需要排除
dhcp server lease day 1 hour 12 minute 0 --- 租期
【静态绑定】
interface Vlanif10
ip address 10.1.1.254 255.255.255.0
dhcp select interface--- 该接口工作在DHCP 的接口模式
dhcp server static-bind ip-address 10.1.1.11 mac-address 5489-989c-074d--- 把10.1.1.11固定分配给某台电脑
