Remote loopback can be disabled either automatically or manually. Perform the following steps on the device on which an interface in active mode resides:
The system view is displayed.
The interface view is displayed.
Remote loopback is disabled on the interface.
After you start remote loopback, you may forget to stop remote loopback, which causes the link to fail to forward service data for a long time. To prevent this issue, remote loopback is automatically disabled after a timeout period. The timeout period of remote loopback is configurable. To disable remote loopback manually, perform this step.
The configuration is committed.
