DULD Settings

The Switch features a D-Link Unidirectional Link Detection (DULD) module. The unidirectional link detection provides a
mechanism that can be used to detect unidirectional link for Ethernet switches whose PHYs do not support unidirectional OAM
operation. This function is established based on OAM, so OAM should be enabled before starting detection.
To view this window, click L2 Features > DULD Settings, as shown below.
