ITL Details
A port in a 2950 will not immediately activate. With the switch lights in the Status mode a connected port will first go orange. Before the device can communicate the port must become green. This is due to spanning tree keeping ports in shutdown when a device is first plugged in. This causes problems with certain devices such as boot time DHCP/BOOTP. You can avoid this by making the switch ports access ports from within the IOS and enable portfast on those ports.
