单台 S5560S-28P-SI交换机上VLAN无法互通问题

单台 S5560S-28P-SI交换机，划分vlan 100 200 300,

#

interface Vlan-interface100

 ip address 192.168.1.254 255.255.255.0

#

interface Vlan-interface200

 ip address 192.168.2.254 255.255.255.0

#

interface Vlan-interface300

 ip address 192.168.3.254 255.255.255.0

三台PC分别接入三个vlan，并分别设置三个IP

192.168.1.200/24    GW:192.168.1.254

192.168.2.200/24    GW:192.168.2.254

192.168.3.200/24    GW:192.168.3.254

Brief information on interfaces in route mode:

Link: ADM - administratively down; Stby - standby

Protocol: (s) - spoofing

Interface            Link Protocol Primary IP      Description               

Vlan1                DOWN DOWN     --             

Vlan100              UP   UP       192.168.1.254  

Vlan200              UP   UP       192.168.2.254  

Vlan300              UP   UP       192.168.3.254  

在交换机上能分别ping通3台PC，

3台PC都能ping通 192.168.1.254 192.168.2.254 192.168.3.254

3台PC不能互相ping通

查过交换机说默认是开通路由的，但电脑就是不能互通，不知道哪里设置问题

单台3层交换机组网划分3个VLAN
