(2) 对于Trunk端口和Hybrid端口,如果系统发现端口被环回,则向终端上报log和trap信息,如果用户还从以下两个功能中选择了一个进行开启,则可以进一步控制环回端口的状态:l 开启端口的环回监测受控功能loopback-detection control enable:系统则将该端口置为block状态(处于该状态的端口不能转发数据报文)并向终端上报lo...
port trunk permit vlan all loopback-detection enable loopback-detection control enable loopback-detection per-vlan enable description to_3#2F_N 我咨询了H3C技术支持 :loopback-detection control enable 打开后会向终端上报log和trap信息的功能,其端口也会被置为block状态。(紫色字体 是我理解,认同的支持下!
2、开启相应端口监测 >int gig 1/0/1 loopback-detection enable 3、如为trunk端口,1和2步只能对trunk端口的默认vlan进行监测,需要对所有vlan开启监测 loopback-detection per-vlan en 4、如为trunk端口,发现环路仅上报错误,需要设置端口受控,access端口不需要。 loopback-detection control en 原理 环回监测会在...

In addition, the device takes the pre-configured action (see Action Taken After a Loop Is Detected) on the problematic interface to control the interface and reduce the impact of the loop on the device and network. The controlled interface continues to send detection packets. If the device ...

When testing some special functions such as locating an Ethernet fault, you must enable loopback detection on the Ethernet interface to check whether the interface is working properly. When no fault occurs on the Ethernet interface, the physical and protocol interface statuses are always Up after ...
