Well there's your problem I suspect. When you connect everything to a
100M switch for testing, I'd guess that switch doesn't have Spanning
Tree enabled.
You need to turn on Rapid Spanning Tree, aka portfast, aka several
other things I'd imagine. That way, when the client connects, the
port will go immediately to enabled (so DHCP will work), but if
someone 'accidentally' creates a loop, it will be turned off quickly
enough that it won't kill the network.
