DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch
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.
