You can allow a remote entity to set a local interface into remote loopback mode on all
Ethernet interfaces on the E Series routers in which OAM link-fault management support
is present. When a remote-loopback request is sent by a remote entity, the JunosE
Software places the local interface into loopback mode. When an interface is in loopback
mode, all frames except OAM PDUs are looped back without any changes to the frames.
OAM PDUs continue to be sent to the management plane and processed. By default, the
remote loopback feature is not enabled.
The following example configures the Gigabit Ethernet interface for OAM link-fault
management and enables it to be placed in remote loopback mode to respond to
loopback requests from the peer.

Display the results of the Ethernet OAM link-fault management discovery process for a
particular interface, such as the hardware status of the interface, operational status of
the interface, status of the established link discovery mode of the local and remote OAM
entities, states of the multiplier and parser functions of the OAM sublayer for the local
and remote OAM entities, and functionalities and configuration of the local and remote
OAM entities.
To display information regarding the OAM discovery process for a specific interface:
