华为三层交换机 配置VLAN 基于接口开启DHCP

1、拓扑图

 2、SW2 配置 VLAN

<HuaWei>sys

# 关闭消息提示
[SW2]undo info en

# 交换机命名
[Huawei]sys SW2

# 批量创建 VLAN 10 20
[SW2]vlan batch 10 20

# 配置 VLAN
[SW2]int e0/0/1
[SW2-Ethernet0/0/1]p l a
[SW2-Ethernet0/0/1]p d v 10
[SW2-Ethernet0/0/1]int e0/0/2
[SW2-Ethernet0/0/2]p l a
[SW2-Ethernet0/0/2]p d v 20
[SW2-Ethernet0/0/2]int e0/0/3
[SW2-Ethernet0/0/3]p l t
[SW2-Ethernet0/0/3]p t a v a

3、SW1 开启 DHCP

<Huawei>sys
[Huawei]sys SW1

# 批量创建 VLAN
[SW1]vlan batch 10 20

# 进入接口
[SW1]int g0/0/1

# 设置为 trunk
[SW1-GigabitEthernet0/0/1]p l t

# 允许所有VLAN通过
[SW1-GigabitEthernet0/0/1]p t a v a

# 开启交换机DHCP功能
[SW1]dhcp enable

# 进入 VLAN10
[SW1]int vlanif 10

# 配置IP，这里就是指网关
[SW1-Vlanif10]ip addr 192.168.10.1 24

# vlanif10 开启 DHCP
[SW1-Vlanif10]dhcp select int

# 配置DHCP的DNS
[SW1-Vlanif10]dhcp server dns-list 114.114.114.114

# 配置 VLAN 20
[SW1-Vlanif10]int vlanif 20
[SW1-Vlanif20]ip addr 192.168.20.1 24
[SW1-Vlanif20]dhcp select int
[SW1-Vlanif20]dhcp server dns-list 114.114.114.114

4、查看 PC

PC1>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fe2a:e09
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.10.254
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.10.1
Physical address..................: 54-89-98-2A-0E-09
DNS server........................: 114.114.114.114

PC2>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fee3:6765
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.20.254
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.20.1
Physical address..................: 54-89-98-E3-67-65
DNS server........................: 114.114.114.114

 5、其它 DHCP 命令

# 配置IP地址有效期
dhcp server lease day 2 hour 0 minute 0

# 配置不参与分配的IP地址范围
dhcp server excluded-ip-address 192.168.10.2 192.168.10.100

# 绑定固定地址
dhcp server static-bind ip-address 192.168.10.150 mac-address 5489-982A-0E09
