14.3 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
Figure 14-3 Typical
OAM application topology
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
