网络拓扑
其中SW-1交换机和SW-2交换机接口规划为：
Ethernet 0/0/1 VLAN ID为10，接口类型access
Ethernet 0/0/2 VLAN ID为10，接口类型access
Ethernet 0/0/5 VLAN ID为20，接口类型access
Ethernet 0/0/6 VLAN ID为20，接口类型access
GE 0/0/1 VLAN ID为1、10、20，接口类型为trunk
Host-1 ip为192.168.64.11/24
Host-2 ip为192.168.64.12/24
Host-3 ip为192.168.64.21/24
Host-4 ip为192.168.64.22/24
Host-5 ip为192.168.64.13/24
Host-6 ip为192.168.64.14/24
Host-7 ip为192.168.64.23/24
Host-8 ip为192.168.64.24/24
网关都为192.168.64.254

测试同交换机下，同一VLAN主机可以通信。
不同交换机下，同一VLAN主机也可以通信。
不同VLAN主机则不能通信。
