The following fields are displayed for all UDLD-enabled ports.
•
Interface Name
—Name of the local UDLD-enabled port.
•
Neighbor Information:
-
Device ID
—ID of the remote device.
-
Device MAC
—MAC address of the remote device.
-
Device Name
—Name of the remote device.
-
Port ID
—Name of the remote port.
•
State
—State of the link between the local and neighboring device on the
local port. The following values are possible:
-
Detection
—The latest UDLD state of the port is in the process of being
determined. Expiration time has not yet expired since the last
determination (if there was one), or since UDLD began running on the
port, so that the state is not yet determined.
-
Bidirectional
—Traffic sent by the local device is received by its
neighbor, and traffic from the neighbor is received by the local device.
-
Undetermined
—The state of the link between the port and its
connected port cannot be determined either because no UDLD
message was received or the UDLD message did not contain the local
device ID in it.
-
Disabled
—UDLD has been disabled on this port.
-
Shutdown
—The port has been shut down because its link with the
connected device is undetermined in aggressive mode.
•
Neighbor Expiration Time (Sec.)
—Displays the time that must pass before
the device attempts to determine the port UDLD status. This is three times
the Message Time.
•
Neighbor Message Time (Sec.)
—Displays the time between UDLD
messages.
