Port activation delay on 2924XL

    When a computer is powered on, the cisco switch keeps that newly activaled
    ethernet port in "amber" for about 30 seconds. According to what I read,
    this is to ensure that any spanning tree issues are handled should that
    port be connected to another switch/router.

    Is there a way to configure an interface to tell the switch that there are
    never to be any spanning tree issues on that port and to activate it as
    soon as it sees a signal on it ? (aka, when it is a single computer
    connected to a port).

    I have machines that boot off the network, so delay in forwarding traffic
    means delay in the start of the boot process.

    Correct. Spanning tree.
