(Optional) Configuring the Working Mode of DLDP

Context

If DLDP works in normal mode, the system can identify only unidirectional links caused by intersected fibers.

If DLDP works in enhanced mode, the system can identify unidirectional links caused by intersected fibers or fiber disconnection. To detect unidirectional links caused by disconnection of one optical fiber, manually set the rate and full duplex mode of the connected interfaces. If you do not set the rate and full duplex mode of the connected interfaces, DLDP does not take effect even if it is enabled.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    dldp work-mode { enhance | normal }

    The working mode of DLDP is configured.

    By default, the working mode of DLDP is enhance.
