在全局开启loopback-detection enable，同时在1,2端口下开启，

# interface Ethernet1/0/1 

 port access vlan 51 

 loopback-detection enable 

#

 interface Ethernet1/0/2 

 port access vlan 51 

 loopback-detection enable

此时使用网线将1,2端口连接，

同时查看display loopback-detection，显示

Loopback-detection is running

Detection interval time is 30 seconds 

There is no port existing loopback link，是设备版本问题还是命令配置问题，谢谢
