It means that it will behave like any STP port in forwarding state -- forward packets until it detects a loop. The "problem" is that if you were to link the networks together using portfast ports then it could take 5-20 seconds for the switch to get a clue. (I've never seen it take longer if enough traffic to create a problem was transiting the port) -- Jo Rhett senior geek SVcolo : Silicon Valley Colocation
