H3C ↑560 vlan互通

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：

[SW1]dis dhcp server ip-in-use

IP address       Client identifier/    Lease expiration      Type

                 Hardware address

192.168.10.2     0033-3661-612e-3339-  Dec 10 21:35:46 2019  Auto(C)

                 3463-2e30-3230-362d-

                 4745-302f-302f-31

192.168.20.2     0033-3661-612e-3430-  Dec 10 21:35:55 2019  Auto(C)

                 3135-2e30-3330-362d-
