on the access side where you might have issues with stp is if your customer is then connecting to a cisco switch these stp messages between equipment can get funny and start shutting off ports because one side supports it and the other doesn't. you'll go crazy locating these issues.

There's nothing wrong with a loop protect on an access port, but since its not an official standard, there will be variances in loop detection algorithm quality and design between vendors. YMMV. That said, there's nothing wrong with STP on access ports either. On Oct 25, 2016 4:27 PM, "George Skorup" <[email protected]<mailto:[email protected]>> wrote: Care to explain?

If all you care about is stopping a loop, then use that. Use STP if you need its functionality.
