H3C DHCP

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}

DHCP服务器显示及维护

    ·显示DHCP地址池的可用地址信息

    [Router]display dhcp server free-ip

    ·显示DHCP服务器的统计信息

    [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

    [Router-Ethernet1/1]dhcp select relay

    ·配置接口与DHCP组关联

    [Router-Ethernet1/1]dhcp relay server-select group-id

DHCP中继显示及维护

    ·显示接口对应的DHCP服务器组的信息

    [Router]display dhcp relay{all|interface interface-type interface-number}

    ·显示DHCP服务器组中服务器的IP地址

    [Router]display dhcp relay server-group{group-id|all}

    ·显示DHCP中继的相关报文统计信息

    [Router]display dhcp relay statisitcs[server-group{group-id|all}]
