Hello Lazaros,
Thank you for such a detailed and helpful reply! I agree and I’m just assuming the Cisco documentation is worded poorly and should state the method of detection when detecting a unidirectional link - implicit or explicit.
The main confusion for me came from several other resources stating that Normal mode would under no circumstances error disable the link.
However, now we both know that to be incorrect and it depends on whether UDLD implicitly or explicitly detects a unidirectional link.
Will Rene be updating the section to mention how implicit and explicit detection determines the action taken based on UDLD operating mode?
