VLAN的IP设置
给VLAN分配IP地址（配置真实网关）
[LSW1]int vlan 10 进入VLAN 10
[LSW1-Vlanif10]ip add 192.168.10.1 24
[LSW1-Vlanif10]int vlan 20
[LSW1-Vlanif20]ip add 192.168.20.1 24
[LSW1-Vlanif20]int vlan 30
[LSW1-Vlanif30]ip add 192.168.30.1 24
[LSW1-Vlanif30]int vlan 40
[LSW1-Vlanif40]ip add 192.168.40.1 24
[LSW1-Vlanif40]int vlan 50
[LSW1-Vlanif50]ip add 192.168.50.1 24
[LSW1-Vlanif50]int vlan 60
[LSW1-Vlanif60]ip add 192.168.60.1 24
[LSW1-Vlanif60]quit
l 核心层交换机LSW２
与LSW１类似，创建VLAN、配置好接口、设置真实网关（与S１地址不同）
[LSW2]vlan 10 建立VLAN 10
[LSW2-vlan10]vlan 20
[LSW2-vlan20]vlan 30
[LSW2-vlan30]vlan 40
[LSW2-vlan40]quit
[LSW2]int g0/0/1 进入端口1
[LSW2-GigabitEthernet0/0/1]port link-t t 配置端口为Trunk模式
[LSW2GigabitEthernet0/0/1]port t allow vlan all 配置端口为允许所有VLAN通过
[LSW2-GigabitEthernet0/0/1]int g0/0/2
[LSW2-GigabitEthernet0/0/2]port link-t t
[LSW2GigabitEthernet0/0/2]port t allow vlan all
[LSW2-GigabitEthernet0/0/2]int g0/0/3
[LSW2-GigabitEthernet0/0/3]port link-t t
[LSW2-GigabitEthernet0/0/3]port t allow vlan all
[LSW2-GigabitEthernet0/0/3]quit
[LSW2]vlan 70
[LSW2-vlan70]int g0/0/4 进入端口4
[LSW2-GigabitEthernet0/0/4]port link-t a 配置端口为access模式
[LSW2-GigabitEthernet0/0/4]port de vlan 70 配置该端口允许VLAN 70通过
[LSW2-GigabitEthernet0/0/4]quit
[LSW2]int vlan 10 进入VLAN 10
[LSW2-Vlanif10]ip add 192.168.10.2 24 配置VLAN真实网关 配置子网掩码为24位
[LSW2-Vlanif10]int vlan 20
[LSW2-Vlanif20]ip add 192.168.20.2 24
[LSW2-Vlanif20]int vlan 30
[LSW2-Vlanif30]ip add 192.168.30.2 24
[LSW2-Vlanif30]int vlan 40
[LSW2-Vlanif40]ip add 192.168.40.2 24
[LSW2-Vlanif40]int vlan 70
[LSW2-Vlanif70]ip add 192.168.70.2 24
[LSW2-Vlanif70]quit
