Example: Enabling Remote Loopback Support on the Local Interface

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.

Purpose
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:
Action
