11.3 EFM OAM Example
Example:
CE and PE devices with point-to-
point link enable EFM OAM to monitor “the First Mile” link
performance. It will report the log information to network management system when occurring
fault event and use remote loopback function to detect the link in necessary instance

Typical OAM application topology
Configuration procedure: (Omitting SNMP and Log configuration in the following)
Configuration on CE:
CE(config)#interface ethernet 1/1
CE (config-if-ethernet1/1)#ethernet-oam mode passive
CE (config-if-ethernet1/1)#ethernet-oam
CE (config-if-ethernet1/1)#ethernet-oam remote-loopback supported
Other parameters use the default configuration.
Configuration on PE:
PE(config)#interface ethernet 1/1
PE (config-if-ethernet1/1)#ethernet-oam
Other parameters use the default configuration.
Execute the following command when using remote loopback.
PE(config-if-ethernet1/1)#ethernet-oam remote-loopback
Execute the following command to make one of OAM peers exiting OAM loopback after
complete detection.
PE(config-if-ethernet1/1)# no ethernet-oam remote-loopback
Execute the following command without supporting remote loopback.
CE(config-if-ethernet1/1)#no ethernet-oam remote-loopback supported
11.4 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.
