Configuring Loopback Detection

Configuring Loopback Detection

Context

Performing loopback detection affects system performance. After loopback detection is performed, run the undo ft1 loopback command immediately to disable loopback detection.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface serial interface-number

    The T1-F interface view is displayed.

  3. Run ft1 loopback { local | payload | remote }

    The loopback detection function is enabled and the detection mode is configured.

Follow-up Procedure

Perform either of the following steps depending on the detection mode you configured:

  • If the loopback detection mode is set to local, run the display interface serial interface-number command on the local device to check whether the physical status (current state) of the serial interface is Up.

    If the serial interface is in Up state, the local device can send and receive packets normally. If the serial interface is not in Up state, the local device fails to send and receive packets.

  • If the loopback detection mode is set to remote, run the display interface serial interface-number command on the remote device to check whether the physical status (current state) of the serial interface is Up.

    If the serial interface is in Up state, the link between the local and remote device is working properly. If the serial interface is not in Up state, the link between the local and remote device fails.
