Portfast bypasses the initial phases of spanning tree, it does not disable it. It bypasses 2 or 3 out of the 5 phases.

Subject: Disable Spanning-tree
Hi GS,
I was doing a Cisco ASET lab yesterday and came across a switching task that
basically said that hosts were connected to ports fa0/12 - 14 in VLAN 13 and
they wanted you to configure the ports in such a way to have them come up as
quickly as possible without turning off spanning-tree. My solution was to
reduce the timers for VLAN 13 to their minimums but the solution from Cisco
was to use the portfast command. I was under the impression that when you
applied the portfast command to a switchport it disabled spanning-tree for
that port. Is this a mis-understanding on my part?
thanks,
Lloyd
