spanning-tree portfast trunk
switchport nonegotiate
(that stops negotiation of type of port eg access/trunk/etherchannel etc)

then tweak speed and duplex to your requirements (speed/duplex negotiation causes
delay

carrier-delay msec 0

(that will mean none of the usual things occur and port can go live - use with care)
