拓扑图

配置步骤

1、创建vlan，配置端口所属VLAN和对应VLAN接口的IP地址，IP地址即是对应VLAN的网关地址

vlan 2 to 4

interface GigabitEthernet1/0/1

port link-mode bridge

port access vlan 2

combo enable fiber

interface GigabitEthernet1/0/2

port link-mode bridge

port access vlan 3

combo enable fiber

interface GigabitEthernet1/0/3

port link-mode bridge

port access vlan 4

combo enable fiber

interface Vlan-interface2

ip address 192.168.2.1 255.255.255.0

interface Vlan-interface3

ip address 192.168.3.1 255.255.255.0

interface Vlan-interface4

ip address 192.168.4.1 255.255.255.0

2、配置DHCP地址池2 3 4，用来为192.168.2.0/24、192.168.3.0/24、192.168.4.0/24网段内的客户端分配IP地址

DNS地址114.114.114.114

dhcp server ip-pool vlan2

gateway-list 192.168.2.1

network 192.168.2.0 mask 255.255.255.0

dns-list 114.114.114.114

dhcp server ip-pool vlan3

gateway-list 192.168.3.1

network 192.168.3.0 mask 255.255.255.0

dns-list 114.114.114.114

dhcp server ip-pool vlan4

gateway-list 192.168.4.1

network 192.168.4.0 mask 255.255.255.0

dns-list 114.114.114.114

保留地址不下发

dhcp server forbidden-ip 192.168.2.200 192.168.2.254

配置完成后可通过在交换机上使用display dhcp server ip-in-use命令可以查看DHCP服务器为客户端分配的IP地址。

[H3C]display dhcp server ip-in-use

IP address Client identifier/ Lease expiration Type

             Hardware address

192.168.2.2 0061-6330-322e-6437- Mar 31 18:15:13 2023 Auto(C)

             6165-2e30-3230-362d-

             4745-302f-302f-31

192.168.3.2 0061-6330-322e-6464- Mar 31 18:21:21 2023 Auto(C)

             3339-2e30-3330-362d-

             4745-302f-302f-31

192.168.4.2 0061-6330-322e-6531- Mar 31 18:18:30 2023 Auto(C)

             6537-2e30-3430-362d-

             4745-302f-302f-31

配置完成后，PC_2/ PC_3/ PC_4客户端可以查看IP地址

选中PC机，右键点击配置，启用接口管理，IPV4配置选择DHCP，点击启用，然后刷新，显示IPV4地址状态，其它的PC操作一致。
