Setting a Remote Interface into Loopback Mode

You can configure the software to set the remote DTE into loopback mode on the following interfaces:

• IQ2 and IQ2-E Gigabit Ethernet interfaces
• Ethernet interfaces on the MX Series routers

Junos OS 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 remote-loopback statement at the [edit protocol oam ethernet link-fault-management interface interface-name] hierarchy level:

To take the remote DTE out of loopback mode, remove the remote-loopback statement from the configuration.
