12.3 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 ethernet1/1
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
high
ethernet-oam errored-frame threshold high
{high-frames | none}
no ethernet-oam errored-frame threshold high
Configure the high threshold of errored
frame event, no command restores the
default value. (optional)
ethernet-oam errored-frame-seconds threshold
high {high-frame-seconds | none}
no ethernet-oam errored-frame-seconds
threshold high
Configure the high threshold of errored
frame seconds event, no command
restores the default value. (optional)
