Duld Settings - D-Link DGS-3700-12 User Manual

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.
