Yes I've read about this, but on the specified port there is a switch (Procurve 5412zl the same).

Ok but I can't see that we only use Loop protection on edge port.

In this doc : http://h40060.www4.hp.com/procurve/uk/en/pdfs/application-notes/How_to_improve_and_harden_spanning-tree_configuration_Configuration_note_Dec_08_A4.pdf


It is written, to use loop protect on all ports

Yes I must confess that you're true, and I must wash my eyes before read a documentation.

Thank you for the help.
