If you know of ports that don't want to be able to be trunks or uplink
ports, you can use bpdu guard, this will prevent BPDUs from being
exchanged on those ports.

Anyone can conseil? I know that if you configure 2 ports of the same switches as protected, the traffic that comes from the first can not go out throught the second, and it seems this can help if you have edges switches with 2 uplinks (1 forwarding, 1 blocking),,, but i don't see clearly if protected ports feature can help to STP or it is designed to other purpouses...
