Impact on the System

The loop on the interface has been removed.

  • If the fibers on the interface are connected correctly and the loop is removed, services on the interface are resumed.
  • If the interface is shut down, the interface cannot work.

Possible Causes

Cause 1: The fibers on the interface were connected correctly and the loop was removed.

Cause 2: The interface was shut down.


  1. Run the display dldp command to check the DLDP status on the interface.

    • If the DLDP port state field displays advertisement, the loop has been removed and no further action is required.

    • If the DLDP port state field displays inactive, go to step 2.

  2. Check whether the interface is in Down state.

    • If so, connect the fibers correctly. When the interface goes Up, go to step 1.
    • If not, contact technical support personnel.
