Good Day

Just a quick query. Can UDLD and Loop Guard be enabled on the same interface?


I have this problem too.

Hello Neil,

yes you can and for example we do this in campus network.

To be noted if using any form of Rapid STP 802.1s MST or RPVST UDLD is actually too slow in comparison to rapid STP convergence time.

Enabling both provides the benefit of having multiple methods to detect possible problems.

Hope to help
