RSTP and STP edge port vs portfast

Hey guys,

I work for a company and we setup a bunch of switches. I used RSTP Edgeport bpdu guard. I was assuming that the edgeport part of that line would enable port fast but it didn’t.

Now I know that if I enable spanning a tree port fast that my port will begin forwarding immediately but I’m confused.

What if or can I, add rstp edge port command by itself? So like this:

RSTP edge port RSTP edge port BPDU guard

Or:

Spanning tree portfast RSTP edge port BPDU guard

I was under the impression that rstp replaces Stp, but from my previous posts on this thread it seems Stp portfast is still required... am I correct?
