I don't enable UDLD on my box and walk away before checking if it actually
sees the link as bidirectional.

UDLD is extremly simple when compared to STP for example, so a quick test
in the lab is not that hard.

Can you elaborate in which context UDLD false positived? New
configuration/new links or suddenly after working fine for some
time?
