The switch can be configured to detect and disable unidirectional Ethernet
fiber or copper links. When enabled, the protocol advertises a port’s
identity and learns about its neighbors on a specific LAN segment; and
stores information about its neighbors in a cache. It can also send out a
train of echo messages under circumstances that require fast notifications
or re-synchronization of the cached information.
udld
message-interval
This command configures the message interval between UDLD probe
messages for ports in advertisement phase and determined to be
bidirectional. Use the

form to restore the default setting.

During the detection phase, messages are exchanged at the maximum
rate of one per second. After that, if the protocol reaches a stable state and
determines that the link is bidirectional, the message interval is increased
to a configurable value based on a curve known as M1(t), a time-based
function described in RFC 5171.
