- Default —Port receives the value of the Fiber Port UDLD Default State in
the UDLD Global Settings page.
- Disabled —UDLD is disabled on all fiber ports of the device.
- Normal —Device shuts down an interface if it detects that the link is
unidirectional. It issues a notification if the link is undetermined.
- Aggressive —Device shuts down an interface if the link is uni-directional.
If the link is bi-directional, the device shuts down after the UDLD
information times out. The port state is marked as undetermined.
• Bidirectional State —Select the value of this field for the selected port. The
possible states are:
- 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.
• Number of Neighbors —Number of connected devices detected.
