    The command:

    SWITCH-A (config-if)#spanning-tree portfast

    will cause that Port to bypass the "Listening and Learning" stages of Spanning-Tree Root Bridge Port election/convergence process and go directly from Blocking to Forwarding Frames saving about 30+ seconds of time.

    It should only be used on edge network connected access ports where there is no chance of the Switching Loop to occur.


    Google the term and/or do a search on the cisco website and you'll get piles of info. on it.
