UniDirectional Link Detection Commands

The purpose of the UniDirectional Link Detection (UDLD) feature is to detect and avoid
unidirectional links. A unidirectional link is a forwarding anomaly in a Layer 2 communication
channel in which a bi-directional link stops passing traffic in one direction. Use the UDLD
commands to detect unidirectional links' physical ports. UDLD must be enabled on both sides
of the link in order to detect a unidirectional link. The UDLD protocol operates by exchanging
packets containing information about neighboring devices.
