The efm enable command enables EFM OAM globally.
The undo efm enable command disables EFM OAM globally.
By default, EFM OAM is disabled globally.
Usage Scenario
You can configure EFM OAM for link connectivity detection, link monitoring, remote fault notification, and remote loopback between two directly connected devices.
EFM OAM is usually applied between CEs and PEs to ensure the reliability and stability of user and carrier networks.Configuration Impact
You can perform EFM OAM-related operations only after EFM OAM is enabled globally.
Precautions
After the undo efm enable command is run to disable EFM OAM globally, the device automatically deletes all EFM OAM-related configurations. If the undo efm enable command is run when the local device performs remote loopback and sends a large number of testing packets, a large number of testing packets may be forwarded.
