Configuration procedure: (Omitting SNMP and Log configuration in the following)
Configuration on CE:
CE(config)#interface ethernet 1/0/1
CE (config-if-ethernet1/0/1)#ethernet-oam mode passive
CE (config-if-ethernet1/0/1)#ethernet-oam
CE (config-if-ethernet1/0/1)#ethernet-oam remote-loopback supported
Other parameters use the default configuration.
Configuration on PE:
PE(config)#interface ethernet 1/0/1
PE (config-if-ethernet1/0/1)#ethernet-oam
Other parameters use the default configuration.
Execute the following command when using remote loopback.
PE(config-if-ethernet1/0/1)#ethernet-oam remote-loopback
Execute the following command to make one of OAM peers exiting OAM loopback after complete
detection.
PE(config-if-ethernet1/0/1)# no ethernet-oam remote-loopback
Execute the following command without supporting remote loopback.
CE(config-if-ethernet1/0/1)#no ethernet-oam remote-loopback supported
14.4 EFM OAM Troubleshooting
When using EFM OAM, it occurs the problem, please check whether the problem is resulted by the following
reasons:
 Check whether OAM entities of two peers of link in passive mode. If so, EFM OAM connection can not
be established between two OAM entities.
 Ensuring SNMP configuration is correct, or else errored event can not be reported to network
management system.
 Link does not normally communicate in OAM loopback mode, it should cancel remote loopback in time
after detect the link performance.
 Ensuring the used board supports remote loopback function.
 Port should not configure STP, MRPP, ULPP, Flow Control, loopback detection functions after it enables
OAM loopback function, because OAM remote loopback function and these functions are mutually
