message-interval

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.

Configures the message interval between UDLD

probe messages

udld aggressive

Sets UDLD to aggressive mode on an interface

Enables UDLD on an interface

Shows UDLD configuration settings and

operational status

This command configures the message interval between UDLD probe

messages for ports in advertisement phase and determined to be

bidirectional. Use the no form to restore the default setting.

udld message-interval message-interval

no message-interval

message-interval – The interval at which a port sends UDLD probe

messages after linkup or detection phases. (Range: 7-90 seconds)

Global Configuration

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.
