三层交换机2台（核心交换A和汇聚交换B），在交换机A上添加两个Vlan（Vlan 10和Vlan200）；Vlan 10的网段设为192.168.10.0/24（子网掩码255.255.255.0），网关地址设为192.168.10.1，交换机5到8号端口划入Vlan10；Vlan 200的网段设为192.168.200.0/24（子网掩码255.255.255.0），网关地址设为192.168.200.1，交换机10到20号端口划入Vlan200；Phantosys服务器IP地址192.168.200.77，放在Vlan200；
在交换机B上添加两个Vlan（Vlan 10和Vlan20）；Vlan 10的网段设为192.168.10.0/24（子网掩码255.255.255.0），网关地址设为192.168.10.2，交换机10到20号端口划入Vlan10；Vlan 20的网段设为192.168.20.0/24（子网掩码255.255.255.0），网关地址设为192.168.20.1，交换机21到24号端口划入Vlan20；客户端放在Vlan20。
交换机A的5号口与交换机B的13号口做Trunk。
