I'm trying to enable RSTP on all my ports. I'm following the guide from this faq. Here they say you also need to apply the STP setting on the port profiles. When going to my profiles I can only view them but I can't seem to edit them. So I have following questions:

1. Do I need to recreate all my profiles using the new STP setting or is there a way to edit the existing ones.

2. Why is this a setting in 2 places? Shouldn't enabling it on the switch or port be enough, instead of both?

3. Is enabling STP on all port a good practice in the first place? (A quick general search seems to agree but I'm not sure since it's not the default)
