思科DHCP基本配置

DHCP服务端配置

R1(config)#interface GigabitEthernet0/0

R1(config)#ip address 192.168.1.254 255.255.255.0

R1(config)# no shutdown

R1(config)#ip dhcp pool 1 //创建dhcp地址池

R1(dhcp-config)# network 192.168.1.0 255.255.255.0 //配置分配的网段

R1(dhcp-config)# default-router 192.168.1.254 //配置网关

R1(dhcp-config)# dns-server 1.1.1.1 //配置DNS

R1(config)#ip dhcp excluded-address 192.168.1.100 192.168.1.200> //排除某段自动分配的地址

R1(config)#ip dhcp excluded-address 192.168.1.201> //排除某个分配的地址

查看dhcp状态
