Web4 apr. 2024 · In aggressive mode, UDLD can also detect unidirectional links due to one-way traffic on fiber-optic and twisted-pair links and to misconnected ports on fiber-optic links. In normal and aggressive modes, UDLD works with the Layer 1 mechanisms to learn the physical status of a link. WebUDLD is the layer 2 protocol which enables the devices that are connected through twisted pair Ethernet or fiber optic cables to check the physical configuration and detecting a unidirectional link of the cables.
