dhcp relay address-check enable命令用来使能DHCP中继的地址匹配检查功能。undo dhcp relay address-check enable命令用来禁止DHCP中继的地址匹配检查功能。缺省情况下,禁止DHCP中继的地址匹配检查功能。接口上使能该功能后,当客户端通过DHCP中继从DHCP服务器获取到IP地址时,DHCP中继可以自动记录客户端IP地址与MAC地址的绑定...

执行命令dhcp relay server-ipip-address,配置DHCP服务器的IP地址。 缺省情况下,未配置DHCP服务器的IP地址。 每个接口下最多可配置8个DHCP服务器地址。 (可选)执行命令dhcp relay gateway-switch enable,使能DHCP中继网关切换功能。 缺省情况下,DHCP中继网关切换功能处于未使能状态。

dhcp enable命令是DHCP相关功能的总开关,DHCP Relay、DHCP Snooping、DHCP Server等功能都要在执行dhcp enable命令使能DHCP功能后才会生效。执行undo dhcp enable命令后,设备上所有的DHCP相关的配置会被删除;再次执行dhcp enable命令使能DHCP功能后,设备上所有DHCP相关配置将被恢复为缺省配置。 开启DHCP功能后,如果使能了ST...
DHCP Relay DHCP Relay即DHCP中继,它是为解决DHCP服务器和DHCP客户端不在同一个广播域而提出的,提供了对DHCP广播报文的中继转发功能,能够把DHCP客户端的广播报文“透明地”传送到其它广播域的DHCP服务器上,同样也能够把DHCP服务器端的应答报文“透明地”传送到其它广播域的DHCP客户端。
