在三层交换机配置DHCP功能

> 以华为的交换机为例
> 采用[组建多VLAN多网段局域网][1]这个拓扑

### 1、在三层交换机开启dhcp功能

[Huawei]dhcp enable

### 2、创建地址池
bumenA是自定义的名字，部门A

[Huawei]ip pool bumenA
    [Huawei-ip-pool-bumena]network 192.168.1.0 mask 255.255.255.0
    [Huawei-ip-pool-bumena]gateway-list 192.168.1.254
    [Huawei-ip-pool-bumena]dns-list 114.114.114.114

[Huawei-ip-pool-bumena]ip pool bumenB
    [Huawei-ip-pool-bumenb]network 192.168.2.0 mask 255.255.255.0
    [Huawei-ip-pool-bumenb]gateway-list 192.168.2.254
    [Huawei-ip-pool-bumenb]dns-list 114.114.114.114

### 3、在网关接口启用dhcp

[Huawei-ip-pool-bumenb]int vlan 20
    [Huawei-Vlanif20]dhcp select global 
    [Huawei-Vlanif20]int vlan 10
    [Huawei-Vlanif10]dhcp select global

### 4、更多配置

ip pool 2F 创建一个地址池，名字叫2F配置网关
    gateway-list 192.168.20.1 分配网关
    network 192.168.20.0 mask 255.255.0 分配地址段
    excluded-ip-address 192.168.20.43 192.168.20.253 排除一些地址，不会再给主机分配
    static-bind ip-address 192.168.20.40 mac-address e0d5-5ed7-06e0 静态绑定
    static-bind ip-address 192.168.20.41 mac-address b42e-9911-fdf9
    lease day 0 hour 8 minute0 租约
    dns-list 58.20.127.170 114.114.114 可以配置两台dns服务器
