loop Guard /UDLD

I need to verify if this is Correct:
 If L2 link (Trunk) exists between 2 switches. Loopguard /UDLP should be configured on every port on both  switches including on the ports linking the  switches (Trunk ports)

Thank you

Yes, on trunk ports only since mechanism both enchansments are using is BPDU. If there is no BPDU on port link will be err-disabled (ports to any device that is not sending BPDU will be error disabled (UDLD will err-disable port only if aggressive mode is configured)).

Yes, on ports between switches. Typically only one of those, since they are pretty similar.
