实战 | HCL模拟器实现交换机DHCP配置案例 https://mp.weixin.qq.com/s/D2h5uHOxJc5YlrFJxphlNQ
组网及说明
现有一台S5820交换机,连接两个不同的局域网,现要求两个不同的局域网通过DHCP自动获取IP地址后实现互联互通。
网络拓扑图如下:
配置步骤
(1)将交换机的名字修改为SW1
(2)在交换机分别创建VLAN 10、VLAN 20
(3)VLAN 10的IP设置为:192.168.10.1 255.255.255.0
(4)VLAN 20的IP设置为:192.168.20.1 255.255.255.0
(5)将F0/1端口划分到VLAN 10
(6)将F0/2端口划分到VLAN 20
(7)开启DHCP功能
(8)分别创建两个地址池,分配子网、默认网关、DNS
(9)PC_2和PC_3都能通过DHCP自动获取IP地址
配置关键点
将交换机的名字修改为SW1:
system-view[H3C]sysname SW1
在交换机分别创建VLAN 10、VLAN 20:
[SW1]vlan 10[SW1-vlan10]quit[SW1]vlan 20[SW1-vlan20]quit
VLAN 10的IP设置为:192.168.10.1 255.255.255.0:
[SW1]int vlan 10[SW1-Vlan-interface10]ip address 192.168.10.1 24[SW1-Vlan-interface10]quit
VLAN 20的IP设置为:192.168.20.1 255.255.255.0:
[SW1]int vlan 20[SW1-Vlan-interface20]ip address 192.168.20.1 24[SW1-Vlan-interface20]quit
将GI1/0/1端口划分到VLAN 10:
[SW1]int gi 1/0/1[SW1-GigabitEthernet1/0/1]port link-type access[SW1-GigabitEthernet1/0/1]port access vlan 10[SW1-GigabitEthernet1/0/1]quit
将GI1/0/2端口划分到VLAN 20:
[SW1]int gi 1/0/2[SW1-GigabitEthernet1/0/2]port link-type access[SW1-GigabitEthernet1/0/2]port access vlan 20[SW1-GigabitEthernet1/0/2]quit
开启DHCP功能:
[SW1]dhcp enable
创建DHCP地址池,命名为VLAN10,分配网段、子网掩码、默认网关、DNS:
[SW1]dhcp server ip-pool vlan10[SW1-dhcp-pool-vlan10]network 192.168.10.0 mask 255.255.255.0[SW1-dhcp-pool-vlan10]gateway-list 192.168.10.1[SW1-dhcp-pool-vlan10]dns-list 114.114.114.114[SW1-dhcp-pool-vlan10]quit[SW1]
创建DHCP地址池,命名为VLAN20,分配网段、子网掩码、默认网关、DNS:
[SW1]dhcp server ip-pool vlan20[SW1-dhcp-pool-vlan20]network 192.168.20.0 mask 255.255.255.0[SW1-dhcp-pool-vlan20]gateway-list 192.168.20.1[SW1-dhcp-pool-vlan20]dns-list 114.114.114.114[SW1-dhcp-pool-vlan20]quit
PC0和PC1都能通过DHCP自动获取IP地址:
在交换机查看DHCP分配的情况:
