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

CE

PE

802.1ah OAMPDU

Ethernet

1/1

Ethernet

1/1

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.
