Hi all
am i right in saying this is enabled on GE fiber ports by default and switched off on copper ports by default?
should I only enable this on my L3 links between my switces ? and leave it off everywhere else ?

Hi Carl,
UDLD is disabled on all port by default.
I will enabled all the ports with aggressive mode (it will error disabled when it detect unidirectional link).
HTH,

Hi,
In the global config mode, use udld aggressive to enable UDLD aggressive to all ports.

If you would like to enable it per port based, use udld port aggressive to enble it per port.
