DHCP服务器基本配置

DHCP服务器基本配置

·使能DHCP

[Router]dhcp enable

·创建地址池

[Router]dhcp server ip-pool pool-name

·配置动态分配的IP地址范围

[Router-dhcp-pool-0]network network-address [mask-length|mask mask]

·配置为DHCP客户端分配的网关地址

[Router-dhcp-pool-0]gateway-list ip-address

DHCP可选配置

·配置为DHCP客户端分配的DNS服务器地址

[Router-dhcp-pool-0]dns-list ip-address

·配置DHCP地址池中不参与自动分配的IP地址    

[Router]dhcp server forbidden-ip low-ip-address[high-ip-address]

·配置动态分配的IP地址的租用有效期限

[Router-dhcp-pool-0]expired{day day[hour hour[minute minute]]|unlimited}

[Router]display dhcp server statistics

·显示DHCP地址池中不参与与自动分配的IP地址

[Router]display dhcp server forbidden-ip

DHCP中继基本配置

·使能DHCP

[Router]dhcp enable

·配置DHCP服务器组中DHCP服务器的IP地址

[Router]dhcp relay server-group group-id ip ip-address

·配置接口工作的DHCP中继模式
