Unidirectional link detection provides discovery mechanism based on 802.3ah to discovery its neighbor. If the OAM discovery can complete in configured discovery time, it concludes the link is bidirectional. Otherwise, it starts detecting task to detect the link status. Format config duld ports [ | all] {state [enable | disable] | mode [shutdown | normal] | discovery_time } Parameters ports - Specify a range of ports to be used. - Enter the list of ports used for this configuration here. all - Specifies that all the ports will be used for this configuration. state - (Optional) Specifies these ports unidirectional link detection status. The default state is disabled. enable - Specifies that the unidirectional link detection status will be enabled. disable - Specifies that the unidirectional link detection status will be disabled. mode - (Optional) Specifies the mode the unidirectional link detection will be set to. shutdown - If any unidirectional link is detected, disable the port and log an event. normal - Only log an event when a unidirectional link is detected. discovery_time - (Optional) Specifies these ports neighbor discovery time. If the discovery is timeout, the unidirectional link detection will start. The default discovery time is 5 seconds. - Enter the discovery time value here. This value must be between 5 and 65535.
