Overview
DLDP (Device Link Detection Protocol) is a Layer 2 protocol that enables devices
connected through fiber or twisted-pair Ethernet cables to detect whether a unidirectional
link exists.
A unidirectional link occurs whenever traffic sent by a local device is received by its peer
device but traffic from the peer device is not received by the local device.
Unidirectional links can cause a variety of problems, such as spanning-tree topology loops.
Once detecting a unidirectional link, DLDP can shut down the related port automatically or
inform users.
