SwitchB相关配置】

1.创建进入）vlan30

[SwitchB] vlan 30

2.将E0/1加入到vlan30

[SwitchB-vlan30]port Ethernet 0/1

3.实际当中一般将上行端口设置成trunk属性，允许vlan透传

[SwitchB-GigabitEthernet2/1]port link-type trunk

4.允许SwitchC的vlan从G2/1端口透传通过

[SwitchB-GigabitEthernet2/1]port trunk permit vlan 30

5.实际当中一般将上行端口设置成trunk属性，允许vlan透传

[SwitchB-GigabitEthernet1/1]port link-type trunk

6.允许所有的vlan从E0/3端口透传通过，也可以指定具体的vlan值

[SwitchB-GigabitEthernet1/1]port trunk permit vlan 30

7.创建进入）vlan30的虚接口

[SwitchB]interface Vlan-interface 30

8.给vlan30的虚接口配置IP地址

[SwitchB-Vlan-interface30]ip address 10.10.3.1 255.255.255.0

[SwitchB]

9.定义一个DHCP server

[SwitchB]dhcp-server 0 ip 10.10.10.1

[SwitchB-Vlan-interface30]dhcp-server0

10.创建进入）vlan200的虚接口，vlan200用于SwitchB与8016互连

[SwitchB]interface Vlan-interface 200

11.给vlan200的虚接口配置IP地址

[SwitchB-Vlan-interface200]ip address 10.10.10.2 255.255.255.0
