The D-Link Unidirectional Link Detection (DULD) commands in the Command Line Interface (CLI) are listed (along
with the appropriate parameters) in the following table.
Command
config duld
show duld
Each command is listed, in detail, in the following sections.
config duld
Purpose
The command used to configure unidirectional link detection on ports.
Syntax config duld ports [<portlist> | all] {state [enable |disable] | mode [shutdown | normal] |
discovery_time <sec 5-65535>}(1)
Description 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.
Parameters ports - Specify a range of ports to be used.
<portlist> - Enter the list of ports used for this configuration here.
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.
<sec 5-65535> - Enter the discovery time value here. This value must be between 5 and
65535.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To enable unidirectional link detection on port 1:
DES-3528:admin#
Commands: config duld ports 1 state enable
Success
DES-3528:admin#
show duld
Purpose This command is used to show unidirectional link detection information.
Syntax show duld ports {<portlist>}
Description This command is used to show unidirectional link detection information.
Parameters ports - (Optional) Specify a range of ports to be display.
<portlist> - Enter the list of ports to be displayed here.
If no ports are specified, all the ports will be displayed.
Parameters
ports [<portlist> | all] {state [enable |disable] | mode [shutdown | normal] |
discovery_time <sec 5-65535>}(1)
ports {<portlist>}
config duld ports 1 state enable
