Hi all

We are considering to use protected ports (private-vlan edge ports) besides STP on the uplink ports of "non-transit" edge switches, as an extra way to avoid undesirable layer 2 loops. 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...

Opinions and experiences will be greatly apreciated

Regards
