    Nem. Van, hogy elveszti tulajdonsagat, van, hogy forwarding allapotban marad.

    Portfast has two modes of operation. One is global, the other one is per-port configuration. Global configuration will cause access ports to start forwarding traffic immediately, unless BPDU is received on the port. If BPDU is received, port loses portfast status and reverts to normal operation, i.e. passing through all the states.

    On the other hand, enabling portfast feature on the port itself is unconditional. Regardless of any BPDU being received, port will remain in portfast state. This small, but, crucial difference is important for the remainder of our analysis. We will see that history, so to speak, repeats itself.
