根据企业的情况,决定设置DHCP解决IP地址分配的问题,管理员小张通过在网关设备Switch上配置DHCP服务器,实现为企业两个网段内的终端动态分配IP地址。其中,网段10.1.1.0/24内的PC为员工固定办公终端,IP地址租期配置为30天;网段10.1.2.0/24供企业出差人员临时接入网络,IP地址租期配置为1天。

以下是小张进行的相关配置:

(1)在交换机上开启DHCP服务

<HUAWEI> system-view

[HUAWEI] sysname Switch

[Switch] (1)//使能dhcp

//配置交换机上端口Vlan

[Switch] vlan batch 10 to 11

[Switch] (2)

[Switch-GigabitEthernet0/0/1] port link-type access

[Switch-GigabitEthernet0/0/1] (3)

[Switch-GigabitEthernet0/0/1] quit

//配置Vlan虚接口的IP地址信息

[Switch] (4)

[Switch-Vlanif10] (5) //企业为固定办公终端的网段

[Switch-Vlanif10] quit

//设置接口获取DHCP分配地址信息

[Switch] interface vlanif 10

[Switch-Vlanif10] (6) //使能接口采用接口地址池的DHCP服务器功能

[Switch-Vlanif10] dhcp server lease (7) //租期的缺省值为1天,修改租期为30天

[Switch-Vlanif10] dhcp server static-bind ip-address 10.1.1.100 mac-address 286e-d488-b684 //为

Client_1分配固定的IP地址
