Absolutely! I have a client that uses UDLD Aggressive Mode on all switch-to-switch Gig links.
We found out about this the hard way when we had a SUP in a 6509 that had faulty GIG interface; after several spanning-tree "events" and high-level conf. calls with Cisco they informed us about this feature (this was approx. 2 yrs. ago). Since then, we've been using it quite successfully. I have seen some "weirdness" when initially setting up trunks or gig-Etherchannel links (UDLD will sometimes cause the port to go 'err-disable'). Once you get the trunk/GEC link setup though it seems to work pretty well. HTH ~~~~~~~~~~ R.
