What do you think?I couldn't agree more, as long as you have hardware liveliness detection and unidirectional link detection like you have on Ethernet, UDLD will just decrease your availability not increase. As it's control-plane feature and on timely transport of BPDU.
Agreed. UDLD was a net problem for us - I can't think of a single time it performed it's function, but can recall a handful of outages from false-positives.
