etection. UDLD protocol
monitors the physical configuration of the links between devices and ports that support UDLD. It detects the existence of
unidirectional links. Its functionality is to provide mechanisms useful for detecting one-way connections before they create a
loop or other protocol malfunction. RFC 5171 specifies a way at data link layer to detect Uni directional link.
