My understanding of the reason for the existence of the portfast function in the first place had to do with startup times for protocols like IPX. I can recall in one production network I managed, where we ran IP and IPX, it was not uncommon for a machine to boot on the IP side but fail to boot on the IPX side - the IPX side timed out prior to establishing a connection with an IPX server. I could browse the internet, for example, but I was unable to log on to the Novell server. The solution was portfast on all the switchports to which servers and users connected. A router isn't going to care one way or another since it is not logging on to anything. So the answer is that it can't hurt. I'm curious - what is it you think will be gained? > > Thanks my friends.
