Setting A Remote Interface Into Loopback Mode; Enabling Remote Loopback Support On The Local Interface - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

Applying an Action Profile
You can apply an action profile to one or more interfaces.
To apply an action profile to an interface, include the

Setting a Remote Interface into Loopback Mode

You can configure the software to set the remote DTE into loopback mode on the
following interfaces:
JUNOS Software can place a remote DTE into loopback mode (if remote-loopback
mode is supported by the remote DTE). When you place a remote DTE into loopback
mode, the interface receives the remote-loopback request and puts the interface into
remote-loopback mode. When the interface is in remote-loopback mode, all frames
except OAM PDUs are looped back without any changes made to the frames. OAM
PDUs continue to be sent to the management plane and processed.
To configure remote loopback, include the
protocol oam ethernet link-fault-management interface interface-name]
To take the remote DTE out of loopback mode, remove the
from the configuration.

Enabling Remote Loopback Support on the Local Interface

You can allow a remote DTE to set a local interface into remote loopback mode on
IQ2 and IQ2-E Gigabit Ethernet interfaces and all Ethernet interfaces on the MX Series
routers. When a remote-loopback request is sent by a remote DTE, the JUNOS
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.
To enable remote loopback, include the
