Usage Guideline
D-Link's Unidirectional Link Detection is an extension for 802.3ah Ethernet OAM. It provides a
mechanism to detect a unidirectional point-to-point Ethernet link without PHY support. OAM vendor
specific messages are used in the detection. The detection process is started after OAM discovery was
started but does not complete the negotiation in the configured discovery time.
Example
This example shows how to enable and then disable Ethernet OAM unidirectional link detection on
interface 1/0/1.
Switch# configure terminal
Switch(config)# interface eth1/0/1
Switch(config-if)# duld enable
Switch(config-if)# no duld enable
Switch(config-if)#
30-2 duld action
This command is used to configure the Ethernet OAM unidirectional link detection action on the specified
port. To return to the default settings, use the no form of this command.
