• Cause 1: A loop was detected on the interface that has proactive loop detection enabled after it went Up. The interface was then blocked.

  1.Run the display loop-detect trigger trigger-down all command to check whether there is an interface in the trigger-down state.

  • If so, go to Step 2.
  • If not, go to Step 4.

  2.Check whether the interface connection has a loop.

  • If so, go to Step 3.
  • If not, go to Step 4.

  • If not, go to Step 4.

  4.Collect alarm information, log information and configuration information, and then contact technical support personnel.

  • If not, go to Step 3.

  2.Check whether loops occur on the interface and the Layer 2 network connected to the interface.
