4. Enable EFM OAM loopback of port
8.3 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 1/0/1
CE (config-if-ethernet1/0/1)#ethernet-oam mode passive
CE (config-if-ethernet1/0/1)#ethernet-oam
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)
Command
Explanation
Port mode
ethernet-oam remote-loopback
no ethernet-oam remote-loopback
Enable remote EFM OAM entity to
enter OAM loopback mode (its peer
needs to configure OAM loopback
supporting), no command cancels
remote OAM loopback.
ethernet-oam remote-loopback supported
no ethernet-oam remote-loopback supported
Enable remote loopback supporting of
port, no command cancels remote
loopback supporting of port.
