Field Description
Interface Id The interface identifier in short form, e.g. te1/0/1.
Admin Mode The administrative mode of UDLD configured on this
interface. This is either Enabled or Disabled.
UDLD Mode The UDLD mode configured on this interface. This is either
Normal or Aggressive.
UDLD Status The status of the link as determined by UDLD. The options
are:
• Undetermined – UDLD has not collected enough information
to determine the state of the port.
• Not applicable – UDLD is disabled, either globally or on the
port.
•
Shutdown – UDLD has detected a unidirectional link and
shutdown the port. That is, the port is in the D-Disable state.
•
Bidirectional - UDLD has detected a bidirectional link.
•
Undetermined (Link Down) – The port transitions into this
state when the port link physically goes down due to any
reasons other than the port being put into D-Disable mode by
the UDLD protocol on the switch.
