[ no ] ethernet oam lfm

#### Release Information

Command introduced in JunosE Release 11.1.0.

#### Description

Enables 802.3ah Ethernet Operation, Administration, and Maintenance (OAM) link-fault management on an interface. Enabling IEEE 802.3ah OAM functionality on a physical interface automatically triggers the discovery process. The default discovery mode of the OAM entity is active. The no version disables OAM link-fault management on the interface.

| Note: If you enable OAM on an interface without specifying other parameters for the local OAM entity, such as the discovery mode for the OAM entity and the interval at which OAM protocol data units (PDUs) are sent to the remote peer, default values are assigned to all the attributes that are not manually configured.
